very useful for motor calculation, and easy to understand the section 28.

Why speed decreases the motor torque increases

REFERENCE BOOK TO REFER SIMILAR THINGS.PLEASE !

So good material! Thank you!

Very informative. Thank you

sir, can you also explain what is draft force, I heard this when I study the tractor..I wont ask my lecturer coz he always seems to ignore my questions

sir do you teach online class?

Perfect, short and to the point explanation. Really nice. Thank you..!

❤love all your video tutorial very informative and super easy to understand. Thank you for sharing your knowledge❤🇵🇭🇬🇱

Great lesson in a nutshell. Thank you, Luke! I assume you forgot to refer to T13 at the end of step 9 when you wanted to choose 90A. Right?

Very helpful. Thank you!

Are you using you LEFT hand to write?

what is reduce, voltage or current?

Thank you!! This helped clear things up

Really helpful :) Thank you so much

Great job, it was a very interesting lecture

How does he write backwards like that?!

Nice explanation

Would this work with a 1 phase motor as well? Are you running in Direct on Line (50 or 60 hz) or you have an inverter to lower the frequency?

Thanks for your time and effort ☺️

Thank you for your help Luke.

that was an amazing vidoe, thanks alot Mr Luke

THANKS for sharing your knowledge ❤️ very easy to understand

Thanks for taking the time. Good work.

Good explanation! Appreciate the effort in making this vid

if we are spinning the rotor faster the synchronous speed by means of external internal combustion motor will that motor becomes a generator?

nice explanation

what is the voltage and frequency of the supply ?

studying for my second year code final now! thank you for your service

Yooooo

Nice video. I would like to know how you would know how to connect a 3 phase motor if you don't have a motor plate information on the motor .How can you tell if it should be wired in star or delta if you are working blind.

Are you the same Ron who used to be in a band called Alley Brats?

Waste of time

Lyrics: So you want to know about a 3 phase motor More than just the frame, stator and rotor It uses electricity as its source And changes that into mechanical force Full load speed is part of the nameplate Not torque, it’s measured with a prony brake Torque is the product of radius and force But the output power is usually measured by horse Efficiency is always Pout over Pin Never 100% when you count windage and friction Don’t forget to add the electrical loss Hysteresis and eddy currents are part of the cost So you want to know about a 3 phase motor More than just the frame, stator and rotor A rotor with bars is found in a SCIM Skewed to run smooth and made of aluminum Speed times torque over 9.55 Gives power in watts to the drive Speed times torque over 7121 Is output horsepower at full run Windings in the stator that have the same wrap Around the core slots, these are called lap Windings in the stator that have different lengths Are called concentric to support magnetic field strength But there is another motor with another acronym It’s the wound rotor motor also called a WRIM With external resistors, brushes and slip rings This rotor is wrapped with copper windings So you want to know about a 3 phase motor It may be compared to a simple transformer With a shorted secondary, you’ll learn in school That motor torque is shown with the right hand rule

Lyrics: You finally got a grip on your electrical theory But these rotor parameters are making you weary So let’s make it easy right from the start And approach these concepts with the Ezfix chart Synchronous speed is the speed of the stator 120f divided by poles in your calculator Y’also must know slip speed before you begin Its sync speed minus how much the rotor spins Slip is the ratio of slip speed over sync And E, f and X have a direct link Resistance is constant no matter the time but power factor is opposite to the ezfix line If rotor speed is high then the slip is low Which means rotor current will barely flow Active current follows the torque line Power and slip do the same over the run time When rotor speed is up, what happens to Z? Just like slip speed, it goes down instead How can it be that current does the same? Compared to impedance, voltage has more change Breakdown torque happens at the instant That reactance is equal to the rotor’s resistance Add more load and the motor will stall Too many times and it’ll need an overhaul These are only some of the rotor parameters Because its really hard to rhyme the electrical vernacular Don’t forget about the different rotor designs But we’ll save those for another time.

Haha nice! I feel inspired to learn this now! Would take me about 4 years too

Great video, thanks for sharing :)

Good!

Thank you so much.

thing you. i am from soudi arabian and l benfit 😘

Incredibly pace, material, and skill!

You're pretty good but you're no Jack Semple!!! Remember me?

Very nice played

Q: does the angular speed of e.m.f. that generated in rotor cage is exactly the same for stator rotating e.m.f?

You are the best one illustrates how actually motor works ..iam very very grateful

hope could have more videos for cec. it help us understand the 900 pages code book.lol. thanks for the video.

Not clear on a Step#2 You choose AWG8 Is it a size of single wire? or 50A /3? 17A per phase?(per wire?)

Sir can help me to know, what is the size of Isolation Switch.

Thank you Sir for sharing your knowledge.

Good job.
