AC and induction motors explained

In this video I discuss AC motors, in particular, synchronous motors. I then lead on to the physics behind induction motors

Everything was simple, straight forward without fancy words until the last minute when you threw in the word Eddy current and no explanation leaving everyone empty handed. You probably have your reason.

Now that you know, no need to redo the video that wouldn't be fair but now you have to floor to explain it in the description. It is up to you.
Thank you.

Thanks for the video. It really cleared up some things for me.

This is great. Maybe this strays a bit more into engineering or applied physics, but can you do a video on how an induction motor and transformer is used in an electric vehicle like a Tesla to provide propulsion? Is the DC from batteries turned into AC fed to the external stator which powers the squirrel cage rotor? And how is this modulated to control speed? There are a lot of misconceptions out there and very few clear explanations.

Heyo. With the whole AC synchronous motor, are the magnetic poles also alternating in time with the alternating current in order to produce magnetic forces that continue rotation (as opposed to causing the loop to vibrate)? Also, is it the curved radial nature of the magnetic field that prevents the loop from stopping when its plane is vertical (as we see with flattened poles and a horizontal magnetic field) or is there some other mechanism preventing that?

What is needed to cotrol the induction motor? What kind of motor is used in EVs?

[turbocarr]

Are ALL 3 phase motors created equal? Can I use the same controller for any AC motor provided the controller can handle it? How are they different of so?

I was looking at Baldor 6" Bench Grinders. They have approx. 14 different models!
One of the descriptions says: Built for heavy duty grinding, powered by 1/3 hp Baldor PSC type motor (except 612E & 662E which are split phase)
What would be better for that type of bench grinder, a (PSC) Permanent Split Capacitor or a Split Phase motor?
Is one harder or take longer to start? Do you have to spin the wheels to get it going?

hi, would you mind doing one on magnetic flux and magnetic flux density. the physics HSC exam is on the 31st, I'm not sure if I'm excited or petrified!!!

Spicy engineering stuff ...this is not at all high school

¿How does quantity of poles effect rotation speed¿

I have never ever seen a squirrel in a cage. That's just plane silly. Please change your terminology to a hamster or gerbil cage.

What piece of equipment commonly contains a split ring commutator motor? I want to take one apart. Your graphics are supremely awesome but I'm a kinesthetic learner and have to touch & measure with a DMM and Oscope to comprehend as part of my plan to take over the world.

Please post a video on the difference between the Flux Capacitor used in the Back to the Future Delorean and Elon Musk's Tesla S.
