    Horizon as a company has been a pleasure to deal with. Bought Axial Jeep JLU in late Nov 2020 and it had a faulty servo on the DIG function. I live in Canada and Horizon warranty the servo on my word telling them. Shipped prepaid and arrived in less than two weeks. This video is very helpful when being bombarded with what's available to buy for aftermarket motors. So Thanks for making these videos.

    I felt the need to put this out there, the reason for 3 wires vs 2 wires on BL vs B is more so due to the commutation. A brushless esc needs to have an electronic commutator inside rather than the physical of the brushed.

    Thank you. I was always wondering why brushless motors needed a special ESC.

  • @horizonhobby
    @horizonhobby  11 років тому +3

    It is specific to each motor honestly. Most high-performance brushed motors aren't being produced any longer as most of these manufacturers have moved to brushless technology.

  • @horizonhobby
    @horizonhobby  12 років тому

    I understand what you are saying. With any "sealed endbell" motor there is the opportunity to "pop" the endbell off by applying enough pressure to the tabs to make them spread. This motor is not designed to have the timing adjusted once it has been assembled.

    Let us make this even more clear:
    A brushed motor runs the current though the armature making it electromagnetic that interacts with the permanent magnets in the shell of the motor.
    A brushless motor has a rotor with permanent magnets and runs the current in the shell making it electromagnetic that interacts with the rotor.

  • @horizonhobby
    @horizonhobby  11 років тому

    All depends on if you want to go brushed or brushless. I've heard very good things about systems from Novak and Tekin in both brushed and brushless. The Timbuk2 from Novak is quite popular for an ESC along with their 21.5T or 18.5T motors.

  • @aperaturesciences5466
    @aperaturesciences5466 9 років тому +3

    Brushless motors do NOT run on AC, they are DC that is pulsed to different sets of coils. They basically replace the commutator. The basics are the same, Electricity runs through the coil's creating a magnetic field and repel or attract to the permanent magnet that is part of the rotor. The coils are labeled A,B,C and the electricity gets flowed from A-B, then B-C, then C-A and repeat in a circle . Sensored brushless motors have Hall Effect sensors (usually 3) that tell the Electronic speed controller (esc) what the orientation of the rotor is currently in so the ESC knows which set of coils to apply current to.

    • @purrup1
      @purrup1 8 років тому +3

      if you listened he said they basically work on AC, which is true. even though it is technically DC, a waveform that is basically a modified sine wave with a bunch of PWM is what an ESC sends a brushless motor.

  • @SenorBolsa
    @SenorBolsa 9 років тому +1

    I think a better way to explain brushless vs brushed is that a brushed motor uses a mechanical switch to change polarity and a brushless motor uses a computer and solid state electronics to do it. It's like mechanical fuel injection vs electronic fuel injection, the real benefit comes from being able to adjust timings without physical changes to the motor and having less resistance from mechanical parts.

    Kv-A rating of performance for brushless motors. While Kv ratings are occasionally applied to sensored motors, sensorless brushless motors are almost always rated by Kv. The higher the Kv rating of a motor the faster it will be. Kv refers to the number of RPM a motor will produce for each volt of power input to it For example a 1,000Kv motor would produce roughly 7,400 RPM at 7.4 volts.

  • @michaelsmitten302
    @michaelsmitten302 9 років тому

    Almost all electric motors are ac (stepper motors excluded) - in other words the current must somehow be switched in direction every half cycle if dc is applied. In the so-called dc motor this is achieved by the commutator, which reverses the current flow. A brushed ac supplied motor uses slip rings to get the current to the armature. Great channel, thanks

    maybe I missed it but I didn't see anything in this video about using brushed motors for RC crawling. Censored brushless motors do have use in crawling but top competitors still use brushed for lower end torque and slow speed control.

  • @horizonhobby
    @horizonhobby  11 років тому

    Anything besides a 27T brushed motor is considered "Modified". It refers to the racing class the motor is legal to race in. A 13-double is going to push the limits on that ESC but you should be ok.

    • @jameslinden6304
      @jameslinden6304 8 років тому

      Its Lucky If it's able to be swapped for BL, you need a 540 sized motor, which is designated "3650", 36mm diameter, 50mm long. Then pick a KV rating of 2500 to 4000, and make sure its rated at least for a 3S LIPO. Get a cheap kit from eBay and give it a try. They start around $40. A LIPO battery with the right connector is needed too. 2200mah 3S with 25C should be a good starter pack. You can always go to your hobby shop if there's one near and ask. The one near me is awesome.

    motors are a fun hobby in themselves. the sealed 540 motors can be safely opened and if you know what you're doing you can easily change the windings with bigger gauge laminated wire without soldering and have some cheap fun. if you can find small bearings with the right I.D/O.D diameters then you fit them on the front and end race. got 15t and 10t motors in sealed cans with a double 10t in the making all running off a tekin G9. mabuchi and johnson motors can easily be found next to nothing for rebuild or spare bushes. have fun :)

    Will a higher turn number work better for larger tires in terms of overheating? I’m still running the original 20t in my ECX Amp MT and stock tires on 2s expecting it to fail, but it seems to not overheat like my 12T Arrma brushed on 2s does.

    Depends on the size of the motor quite honestly. There are brushless motors for 1/5-scale vehicles that will blow away the power of those for 1/10-scales. Generally the fastest I've seen for 1/10-scale are the 2-4T motors. Crazy fast!

    @horizonhobby  12 років тому

    No argument there, however in terms of RC getting a working and reliable brushless system was a pretty big breakthrough and advancement. You can go back to the days after Nikola Tesla and see the groundwork laid there.

  • @horizonhobby
    @horizonhobby  11 років тому

    Yes and no. A 550 Motor is a slightly longer version of the 540 motor, capable of delivering more torque and power without suffering from power loss. 550 motors tend to be less susceptible to damage from heat, overgearing or other similar issues. Now there are 540 motors that can be used in 4WD SCTs that have the best of both worlds, less weight and exceptional torque.

    @kreynolds1123 5 років тому

    I've built my own bldc motor and am trying to figure out what bldc speed controller would be appropriate.
    First thing, the motor is axial flux. The rotor has 12 poles (6 pole pairs). The stator has three coils wound with 16 gauge wire. The winding are a falharbor type winding with 4 turns (roughly 76 inches of wire in total per coil) adapted to an axial flux design. The stator has a slotless iron backing made from coiled steel banding to reduce the magnetic reluctance.
    Most radial flux bldc designs use 3 coils and two poles. I wonder if 12 pole 4 falharbor serpentine like turns would be roughly equlivent to 24 turns or something else on some of the more standard motors.
    I tried to run it on a cheap bldc controller. The bldc controllers lowest setting drew .6 amp from a 13.4v lead acid battery. That's about 8 watts. At that lowest setting the controller supplied 1.49vac, and if we assumed 100% efficent transfer of 8 watts 100% meant the coils were pulling 5.37 amps. When the motor was turned by a by a drill at 211 rpms, it generated 0.126vac. During testing the cheap chinese controller blew a couple mosfets. But ill try to answer any other questions.
    I might redo the stator with 5 turns on each coil. But there is not much hope for more turns..

    I have used a giant brush less motor for giant scale rc planes One of them would cut out at high throttle and let out a terrible squeal when it did But throttle back and it reset and goes again. There was no over draw in amps and was using the correct voltage The lipos can deliver more then twice what the amp meter showed as being used. My question for you is How important is switching frequency and how likely is that to have been the cause of this?

    nice instuctional video". i have one question out of curiosity because i think i mest my motor up yeterday. i was crawling with my 20t motor doing rock climbing and i guess since the coils on this motor are thicker that maybe thats why its over heating?? i got the motor so hot it was smoking from burming the label off of the motor, i than let it cool down and when i tried to play with it it still worked but the power was almost reduced by 3/4, so im guessing is this due to the magents loosing magnetism because the motor got the magents so hot?? cuz ive heated up a magnet when i was a little kid and remember the heat made the magnet weaker so was just wonderin if thats most likely the cause of the motor acting this way, please let me know what you think.

  • @horizonhobby
    @horizonhobby  12 років тому

    Its not better as much as its just different. A smaller pinion will give you less top speed but better acceleration. A bigger pinion will give you more top speed but cost you acceleration. For running on a track going to a smaller pinion could make you "faster" as the motor may not have to work as hard to clear obstacles or to get out of a corner. For just running in a driveway, open lot or parking lot a bigger pinion will yield higher top speeds.
