    CORRECTIONS: I've trimmed a couple of short sections from the video that were creating confusion. I didn't mean to imply that AC motors use magnets, but the wording during some moments made it sound like I was. Magnetless motors are not a new thing, but optimizing their design for high efficiency, high torque, without rare earths opens the door for more use cases.

      Matt - this is quite a bad video from a technical accuracy perspective. Clearly the subtitles relating to the differences of electrc motors is not within your field of expertise. This really shows as you show one type of motor and refer to it by tge wrong name and attribute the need for permanent magnetics to the wrong types of motors.
      This 17 year old research into different motor designs is impressive considering his age, however not that much different to what hundreds of students 5 years older than him are doing at several universities around the world.
      The claims from the company Turntide are also not worth calling out. Many of the latest air-conditioning systems available are using inverter drives for their inductance motor drives and these inverter drive AC units achieve similar savings compared to conventional systems.

  • @leonardopsantos
    @leonardopsantos Рік тому +65

    A few corrections (electrical engineer here):
    An induction motor does not "switch" the stator polarity. Because it's being fed with AC, it's built so that a rotating magnetic field is generated. The rotor is just a bunch of short-circuited coils. The rotating magnetic field induces a voltage in the rotor, creating another magnetic field that wants to align itself with the stator's rotating field. Suppose the two ever align (in case the rotor is spinning at the same speed as the rotating field). In that case, the rotating field will appear stationary to the rotor (like two cars going down a freeway at the same speed, they're moving in relation to the ground, but not in relation to themselves). The important part is that the stator's field can only spin as fast as the rotor's field. The difference between the speeds is called the slip ratio and is always larger than one for induction motors.
    A synchronous motor works oppositely: the rotor spins as fast as the stator's field. Because they're rotating at the same speed, there's no induced voltage, so the rotor needs either a permanent magnet or an electromagnet to generate its magnetic field. The slip ratio for a synchronous motor is always one.
    A) Induction (asynchronous) motors: no magnets on the rotor.
    B) Synchronous motors: rotor needs magnets.
    In both cases, there's no "switching" like in DC motors.
    The saliency ratio is the ratio between the magnetic reluctances when the rotor poles are aligned with the stator poles and when it's aligned with the gaps. This determines the torque curve.

The challenge today is to refine these well-known and much used principles and designs for high efficiency and suitable power response.

    I'd like to point out two major corrections:
    1 AC induction motors use NO permanent magnets
    The magnetic field is "induced" in the conductive squirrel cage not generated by permanent magnets at all. (FYI it's called a squirrel cage because the rotors typically made of a cylindrical arrangement of copper or aluminum bars similar to a hamster wheel (why it's called a squirrel cage not a hamster wheel I'm not sure))
    2 synchronous reluctance motors are already a excellent alternative to induction motors in fact Tesla already uses a hybrid synchronous reluctance/permanent magnet motor in its cars (specifically because of its high torque high efficiency and reducing the need for expensive magnets)(reluctance motors are only now getting good because of The reduced cost of switching electronics required whereas induction motors require no extra controller to work on AC power, but the premise has been around for a long time and is relatively well developed))
    edit: Thanks for replying and updating accordingly! I completely agree reluctance motors are awesome and should be used more. I just wanted to call attention to the fact that the vast majority of motors (induction motors) have no permanent magnets (and no rare earths)(and efficiencies usually >80%) and that the primary benefit of reluctance motors is (marginally) increased efficiency with little if any torque/performance reduction (rarely is startup torque the primary design factor anyway) but a larger upfront cost (that should trend down as adaption increases)

    Hello, sorry if this is the 200th squirrel cage comment. A large, industrial, three phase motor is named a squirrel cage because of the rotor. It is often high-silicon steel slats filled in with cast aluminum for structure. When you look at the rotor on a workbench, it resembles a hamster wheel or cage fan, ergo squirrel cage. Easy way for us cavemen types to differentiate between motors. Great videos, thank you

  • @rodcarty2
    @rodcarty2 Рік тому +93

    Most industrial AC motors, both single-phase and 3-phase, do not use permanent magnets, they use an induced magnetic field in the rotor (the rotating part) from the stator (non-rotating part) to induce rotation. This principle can also be used in generators, though they typically require at least some residual magnetism to be able to start the magnetic interaction.
    Automotive alternators use no permanent magnets, though they do use a pair of rings (rather than a segmented commutator) with brushes to make contact to the rotor.

    • @brylozketrzyn
      @brylozketrzyn Рік тому +8

      It is used, however in a little different way. For induction motor to work as generator you need to run the rotor faster, than the field in stator is rotating. In the grid you can do it just by connecting the stator to grid and then providing excitation not with DC (like in synchronous generator) but with AC from VFD inverter. If you match angular velocity of field generated by rotor to be around 115% of synchronous field - you have grid-ready generator. Using VFD as excitation is cheaper, than using it to convert all the electricity from large wind turbine to grid frequency (instead of i.e. 15MW converter you need 3MW one). Of course it does not make sense for hydro or thermal power plants, where you can (and have to) adjust mechanical power to keep turbine at speed

No permanent magnets, and no commutator brushes. Dead simple! One version of it emerged as a Black and Decker air compressor. There was also made a low vibration flat twin piston version which was a bit like a free piston engine.

    Matt, when I was taught about induction motors the diagram we were shown for the rotor was two rings at either end axially connected by bars spaced around the rotor. These bars were the current carrying conductors in which the electromotive force would be generated. The rings were what completed the circuit for the necessary current to flow. To me it looks more like an elongated hamster wheel. But I guess squirrel cage sounded better.

    FYI: Tesla uses a hybrid motor type now called a PMSRM (Permanent-Magnet Switched Reluctance Motor). Their goal was efficiency, and they also reduced the use of rare-earth magnets in the process. Using a lot of "secret sauce" software in the drive inverter they were able to take the benefits of each technology and combine them into the most efficient EV motor on the market. In some cars, such as the Model 3 and Y, they still use a cheaper (no rare earths) induction motor in the front for AWD, while the PMSRM is in the rear and is where most of the efficiency gains come from. I also have a UA-cam channel where I explain a lot of Tesla's technology.

    Hi Matt, thanks for another great video. What I‘m missing, though are two things: 1) I think while discussing electric motors needing permanent magnets, it is really important to point out that several brands already use motors without permanent magnets. E.g. Tesla‘s initial drive trains all used asynchronous AC motors without any magnets and asynchronous motors are still widely used in EVs. So just inventing an EV motor without magnets is obviously NOT the real highlight of this young inventor. Which leads me to 2) It would be great to explain the differences and especially the pros and cons of the various electric motors. I think (but don‘t know even after watching your video) that the highlight of the invention is actually that it is a magnet-less synchronous motor. And that we‘d need to point out why you‘d prefer to have that type of motor vs. an asynchronous motor. Also: in an all wheel drive car you normally now have two different motors, one of which regularly is a magnet-less asynchronous motor so that you can simply cut power to the motor if only power is only needed on the other axle.
    Bottom line: a video with an overview of the many synchronous, asynchronous, reluctance, non-reluctance etc. motor-types for an EV and why you‘d want one for a specific purpose in an EV would be great.

I believe is is to do with the problem of low torque in a motor when running slower than it is designed to run. . . . Yes, we are getting up into the high 90% efficiencies with large motors, but presumably that is when running high load and at their designed speed. . . I suspect that Saliency is about improving slow speed performance.. . The mention of heat melting plastic concerns me, because we want motors to run cool for good efficiency.. . Any Heat is lost energy. . . . These days, we use VFD to get good low speed performance out of motors designed for high speed.. . . This is a definition, but actually means nothing : " Saliency is a measure of the reluctance difference between the rotor and the stator around the circumference of the rotor. ". . This means more : " What is the effect of Saliency in synchronous machine?
      Saliency contributes reluctance torque in machines and appears when motor construction causes the stator winding inductance to vary as a function of position. In simpler term, saliency occurs due to non-uniform airgap. "

    Matt - you need to do a video on the Halbach Array for magnets. The Tesla Model 3 motor uses this - and it focuses most of the magnetic field on one side of the array; making it *much* stronger.
    Correction - Nikola Tesla's invention, the induction AC motor does NOT use any permanent magnets. It uses coils of wire on the armature rotor that generate electric current flow from the stator's magnetic fields - which create magnetic fields of their own - which then cause the rotor to spin. It certainly seems like magic, though!

      @@NeilBlanchard In general, it is useful when the torque does not pulsate. And this is mostly achieved by sinusoidal distribution of the magnetic field along the rotation (tangentially). Hallbach can also be designed for sine. But it is unnecessarily expensive, because a lot of the mass of the magnet is consumed along the line of force. In general, with respect to the usual slats, the induction will be in the range of approx. 0.6-1T. And for that, with today's neodymium magnets, a height of approx. 5 mm is sufficient, certainly less than 10 mm in the direction of the line of force. The area perpendicular to the field line must be preserved with respect to the EMF. I designed electric motors for a while.

    The great advantage of using permanent magnet motors in an EV is that they can be switched to become a generator when torque is applied to the motor via the wheels & transmission when the vehicle is slowing down or coasting downhill to partially recharge the battery. Induction motors can't do that. And the idea of using the cloud & remote servers to control your motors is about the most insane thing ever.

    When I went to college in the 1960s, although I was more interested in communications than in motors, I did take a couple of intro classes in motors and generators. There were no rare earth permanent magnets in wide enough use to affect product designs at the time (unless they were classified!), and the most powerful permanent magnets were Alnico, a trademark for an alloy of (obviously) aluminum, nickel, and cobalt. Therefore, permanent magnet motors were only used in toys and miniature electronics, while “business” size motors used the same power supply for the stator field and rotor (at least in DC or universal motors). When used as a generator, the residual magnetic field (hysteresis) in the “soft” iron cores of the stator windings served to generate the current to power the stator when first started (of course, a motor can be a generator when turned by an external force). AC only motors were generally used for clocks and were designed to synchronize their rotation with the power supply frequency. I don’t remember much more about the motor-generator field since I haven’t used that knowledge in the meantime, but it is fascinating that so many advances have been made in the last half century!

    Thank you all, this stuff interests me, but did you know you can pulse electrify a motor, either normal or brush-less. I'm doing simulator experiments, for Electric Air, and Space craft utilizing PEDF's, Pulsed Electric Ducted Fans. As you may know, electrons plus resistance, slow a current but increase temperature, which slows a current even more, causing more heat, a thermal runaway scenario. So for a 4 motor plane, you can pulse the motors at say 5Hz, when a motor is sparked, it will begin to rotate, generating just a little heat, the attached fan will cool the heat, plus it's inertia will make it continue to rotate for a while, cooling or propelling even more, (thrust) exponentially. I only used 5Hz at the beginning, a spark for each motor plus 1 for the accessories, at 50% duty cycle, per second. Multiply by 1000 = 5KHz, there is barely a performance loss but the motors run much cooler, efficient, and with less wear, or breakage, and still leave a little power for accessories. It's an ongoing experiment I'm working on for mostly Cars, SUVs, Airplanes, Spacecraft, Helicopters, but also any computer cooling fan, or system might apply. Air or compressor liquid coolers as well? In my systems, the electric generator runs continuous, charging, but not the load, cycling, or redistributing saving, power, and, you know, cool-ness? Amen?

      It is impressive that the kid developed a motor, but I doubt that is something special, the motors on the market already achieved amazing power density levels while having very good efficiency which is critical for EV industry. There are some other designs that don't require magnets (e.g. AC synchronous with rotating rectifier) but they have lower power density than the current generation of motors. I think that AC induction motor is a good candidate as an alternative for the current generation of motors, helped by a good vector control system (to control it and improve the not so great torque-speed characteristic of induction motor) and a magnetic core molded from a "special" material (similar to ferrite) it can achieve pretty good performances. If they improve the rotor manufacturing process as to use copper bars instead of aluminum and avoid broken bar faults caused by start-stop situations they will have a reliable, efficient and cost effective option.

    Nice video on electric motors. It is good that you highlight new future technologies and possible problems with current tech. However, there are a few problems with the statements within the video. First, a DC motor does not move by aligning magnetic fields but by Lorentz force action (see: en.m.wikipedia.org/wiki/DC_motor).
    Second: An AC motor generates motion by generating a fluctuating magnetic field in the stator, which than affects the rotor . However, there are several AC motor designs. The asynchronous induction motor which uses a squirrel cage (not shown in this video), and several types of synchronous motors i.e. wound-rotor synchronous motor, the synchronous reluctance motor (SyRM), and the permanent magnet synchronous motor. There are others but these are the most important in relation to your video. Only the permanent magnet synchronous motor uses rare earth metals (and only if the magnets are made from these elements), the others use either a ferromagnetic core (reluctance motors), a squirrel cage, or an electro-magnet (coil). The video that you showed was of a wound-rotor synchronous motor with coils on the rotor. These coils require DC current to function as electro-magnets (excitation current) which can be delivered in several ways (i.e. brushed vs brushless en.m.wikipedia.org/wiki/Excitation_(magnetic)) and operate similar to permanent magnet rotors. An induction motor does not operate like this, it moves due to Lorentz force action on the squirrel cage bars after induction by the fluctuating magnetic field in the stator. A good overview of several electric motor designs can be found here en.m.wikipedia.org/wiki/Electric_motor.
    Third: SyRM already exist and are used extensively (e.g. Tesla 3). The switched reluctance motor (SRM) does not work like an induction motor, it works similar to a brushless DC-motor and can be used as a stepper motor (often in conjunction with magnets) (en.m.wikipedia.org/wiki/Reluctance_motor, en.m.wikipedia.org/wiki/Stepper_motor.
    Now I know I'm knit picking a bit here, but your video implies that rare earth metals are in every motor except reluctance motors which isn't the case. Also, reluctance motors are not the answer to every problem. Yes they work well for high speed applications (i.e. SyRM) but have very low torque at low speed. Of course it is great that this kid made a new reluctance motor design with improved performance but it is a little bit weird to show that as if he is solving for a problem that cannot be solved otherwise. The US department of energy is already studying alternatives for rare earth metals in their REACT project .
    (arpa-e.energy.gov/technologies/programs/react#:~:text=The%20projects%20that%20comprise%20ARPA,EV)%20motors%20and%20wind%20generators.).
    It may be a good idea to do a video on electric motors in general and how they work and project some of the problems with their designs, performance, and materials used, and possible future solutions. Again it was a good effort but a bit incorrect, better luck next time.

    Cloud dependent motor sound like a tremendously horrible idea. Imagine the security risk if that cloud server were compromised and the attacker could deactivate all the motors reporting to the cloud or feeding incorrect information to the motors to cause them to severely vibrate out of control. The cloud servers would also require continued maintenance, which I'm sure companies would look to recoup their costs via subscription fee.

    As a note, another way to improve the torque is to use a phase variance between the rotor and the stator. This can be achieved by adjusting the communicator's angle, but it can also be achieved by generating the phases for the rotor and stator by a controller with offsets. These offsets can be adjusted to boost the torque and maximum speed to improve low-end torque without costing maximum speed.

    Smart SRM motors and inverter + induction motors can save 35% or more energy compared to standard line driven induction motors in applications that involve fans and centrifugal pumps which occur often in HVAC applications. That is due to the 'Variable Torque Load' which fans and centrifugal pumps exhibit such that Torque ~ (RPM)^2 and HorsePower ~ (RPM)^3, which means that a 15% reduction in speed can reduce electrical power requirements by 35% to 50%.

I DO love the fact that he has a very practical bent, BUT at some point soon must be introduced to a quality, practical engineering electromagnetics package, perhaps by some generous mentor. It's with some sadness that I would have to say that what he is up to, including the thermal effects, is these days easily simulated. Indeed a modern engineer can sit down at his/her desk and wing off his design ( I know, some is hidden to us right now) in an hour with fully analysis of field and thermal loadings. "Excited field" motors (i.e., "magnetless" design) are in the multitude, and many are already well above the 90% eff level in the high torque regime.

    I believe what you are calling, or whoever, a smart motor is an A/C motor with a VFD (variable frequency drive). A/C motors when started work to immediately to achieve the RPM of the designed stator and rotor. The horse power is relatively low during this cycle. Industry would use clutches or soft starts (torque converter) to allow the electric motor to achieve a higher horse power before engagement. A VFD would allow 100% horse power at a very low RPM by increasing the cycles of the A/C. VFDs were installed on locomotives and mining equipment to improve efficiency and durability. HVAC units began using VFDs to eliminate full power start ups that use as much energy as the electric motor may use with in a half hour or more of use. In Phoenix I upgraded to a variable speed air conditioning unit that dropped my electricity consumption to under 50%. The unit would be running all day long but at much lower speeds for most of the day.

    The original Tesla Model S motors were inductance motors, not permanent magnet based DC motors. Tesla has a bunch of patents on the designs. The permanent magnet motors in the Model 3 were cheaper to manufacture, and lighter, and so that's why they went with that design. Anyway, inductance motors (electric motors that don't use permanent magnets in their design) have already been used to great effect in EVs. Hopefully this new push into optimizing their designs will make them the norm - I never liked the use of rare earth magnets in infrastructural industrial design.

The video mentions Torque, this has been a problem with high speed motors, when starting from stationary.. . These days we use VFD ( Variable Frequency Drives ) to power such motors, so we can now maintain high efficiency and high torque even at low starting speeds, these are also up in the high efficiencies. . So I am not seeing much room for motor improvements, when they are now up in the high 90% efficiencies. . .
