Tesla motor as a generator

Hello.
Question: would tesla motor can be use to produce electricity?
Or tesla motor is completely different then AC/DC brushes motors?
(I’m talking about motor only,disconnected from invertor,capacitors and CPU)

I have i wind turbine business in EU, and looking for most efficient generators.
Since tesla motor so advanced,I thought maybe it can be used as an generators.

Maybe manufacturers are years behind tesla motors.

Thank you for answer and suggestions.

There is nothing advanced about a Tesla motor other than the level of bullshit its CEO spews.

They even lace the windings with string, like was done in the 1800's.

The motors on most models cannot be extricated from the gearcase.

How much a small motor can produce so much power?(if they are the same as other)
Basic physics. Spin it faster.

The word is that a lot of Tesla drives get replaced under warranty. A few times in some cars.

What you wreckin would spinning tesla motor would be able to produce electricity same level as these days generators???

Or can only be used as a motor?
You would need to find the back-emf constant of the tesla motor to know how much voltage would be produced for rpm. Since it is powered from ~400 VDC then it might generate that much voltage at near the max rpm that it is rated.

A better generator would have stronger magnets closer to the air gap with many poles, e.g. 6,8,10 or more , with a 3-phase winding.

It would be interesting to see the bemf of the Ford motor with the hairpin end turn windings.

You saying Tesla motor to use as a generator would be less efficient than having same KW 3 phase 8 poles generator?

The thing is i can have tesla motors for way lower price then actual same KW generator.
Consider the duty cycle. No one runs an EV motor at 100% of maximum rated power continuously.
You won't push it to beyond 25% "max." Even then, it has to be liquid cooled. Good luck with that up on a tower.

You're paying for the amount of iron and copper to do the job reliably and continuously, which the Tesla does not have. That includes a high pole count to keep RPM DOWN. The Tesla runs at 18,000 RPM. You need to gear that by about 600:1 to match the speed of the fan.

The expensive gearbox you'll need to spin up the Tesla to produce any appreciable power and the resulting cogging torque multiplication (assuming you can even use the PM motor in its gearcase, which I seriously doubt - we had a thread here asking how to get the motor out of the case...you can't - it's pressed in permanently) make it totally worthless for wind.

As I said, you have a lot of reading to do, stop listening to the siren song of your wallet, and you need to learn the fundamental rule:

Tesla has made several motors. When people discuss using Tesla motors, they are still usually referring to the original Model S and Model X motors; these are all induction motors, and none of them are still in production. What motor is being asked about in this case?

Whether the motor is one of the old induction motors, the newer induction motor, or a permanent magnet motor, it won't work as a motor or a generator without a suitable controller... and the stock Tesla controller isn't usable without either modification or the use of a supervisory controller.

There are controllers and inventors from wind turbines,I think would be siutable.
However by reading comments I think is not worth it.
Would be easier to order 60kw low rmp generator designed for wind turbines.

Probably the worst possible combination you could come up with.

You have two competing motivators:

- Using junk you have laying around that could build the project cheaply but making a hackjob of it, and

- Spending a lot more to have something purpose built.

Instead, what you've come up with is spending a lot of money on something expensive that is poorly suited to the task, and then making a hackjob of it.

Either get a cheap motor and make it work, or buy a motor suited to a windmill. Heading in really any direction excepet where you are is going to have you save both money and effort.

I mean, i appreciate comments it helped me to understand that tesla motor wouldn’t be siutable for wind turbines which was the main question

Thanks everyone who helped.
Peace.

If you only knew all the whacky half-brained shit I gleefully endorsed people make a go of in this community, you'd have some context as to just how bad an idea yours is that I talked you down from it.
