Induction, reluctance and series/parallel/external excitation electric motors have been around for decades. You likely have a dozen of those in your home in your HVAC system, kitchen appliances, washer, drier, etc. The only thing sort-of-new here is using induction to feed the rotor winding instead of slip rings. Generators at power stations have used small inside-out alternators to feed the rotor winding for decades too, which is fundamentally the same thing albeit with a bit more drag.

That's true but removing the slip rings is mostly what this innovations is all about.

Do they work as well(efficiently) when configured as Axial Flux type?

Yes, you can also makes an axial induction motor if you want to or a wound rotor synchronous motors, uses steel and carbon fiber windings.

Inductive motors are NOT more efficient than permanent magnet motors. They require power to sxcite the field windings. Tesla switched from inductive to PM motors to gain 3-5% efficiency.

Tesla used a classical asynchronous induction motor. This is something different.

so with this technology and Toyota new battery technology, in the future, will the ev cars price tag drop ?

What are the cons on this motor?

To me it looks like the biggest con is that you have additional electronics inside of the motor. So when there is a defect in this electronics, the whole motor needs to be removed and disassembled to repair it.

Probably the absence of the regenerative function of a "normal" electric motor

LUNATIC 2 comments below mine would beg to differ. If he is correct in reporting tesla's supposed action, which I don't doubt! Then efficient, weight, size & longevity are Trumps!

Nothing New in this video about motors ???
