Hi
I've been looking for three phase induction motors to potentially use for an electric conversion in the future. I've found that HPEVS motors are too expensive for my current budget, and I've been looking at the potential of industrial motors. Does anyone know of any 200kw industrial motor that can fit into the bonnet space of a Toyota Supra (4thGen) or a 100kw industrial motor that, if there are two instances of that motor, can fit into the same bonnet space?
Thanks,
Pivotex

Welcome to the forums, Pivotex.
First off, note that you don't need a motor capable of 200 kw continuous, just 200 kW for a minute or less. A good thing too, because a 200 kW industrial motor (which means a comfortable 200 kW 24/7) would weigh as much as the rest of the car. Similarly for the battery; 200 kWh (to supply 200 kW for nearly an hour) would be twice the size of the largest Tesla battery, and would give some 800 km range in city driving.
There is a very long old thread on induction motors; I'll dig it up when I'm at a keyboard.
Edit: I think this is it: Changing an induction motor voltage. At least, you'll get the concept of "overclocking" (really over-voltaging) a motor. That's the other problem with industrial motors: it's hard to find one off the shelf that is wound for low enough voltage. Rewinding or if it's possible rewiring them are ways of changing the voltage.
[ Edit: motor selection -> induction motors ]

I guess 200kw for an electric motor is not the same as 200kw for a petrol engine.
Thanks for the response!

Please scrap the idea of 2 AC motors - that's just crazy talk.
I have no doubt that there is some 11kW industrial motor that could pop out 200kW for short periods.
The problem is NOT the motor but the CONTROLLER.

So the short answer is NO but the long answer is YES.

It'd more likely be 160-frame to handle 200kW.
Ignore the rear shaft.
Usually the limiting dimension is from the bell housing to the opposite side of the engine bay needs to be more than the length of the motor.

You can shorten the motor slightly by removing the rear fan cover and fan.
But you will need to supplement cooling some other way.

kW is kW right
We are force fed advertising hype from the auto makers.
So a cars power is sold to us as PEAK kW - because more is better right!
A mining factory needs an electric motor to move a belt at a given speed all day every day.
So an electric motor is sold as CONTINUOUS kW.
It all comes down to marketing.
As a rough estimate you only need 20kW CONTINUOUS to do 100kph.
The other 180kW only happens when you are under heavy acceleration or excessively speeding.
So would you rather buy a 50kW continuous Supra or a 200kW peak Supra?
Really they are the same Supra.
Depending on industrial AC motor something between 11-22kW should get you to 200kW PEAK.
But as I say you need to find the CONTROLLER and motor as the pair and compare costs and performance.
So the short answer is NO but the long answer is YES.

Anyways, thanks for the input Richo!
If what you say is true, then will a motor like this be capable of peaking at 200kW with the right controller and enough batteries?

And it's a permanent magnet synchronous motor instead of an induction motor, but I would like to get some input on this.
