Toyota's electric power steering motor

[Dxtawise]

Hey everyone. Would need some kind of help here.
I recently replaced the electric DC motor, attached to a Corolla steering column, and instead of throwing it away, I just thought, it would be helpful in my planned electric bicycle conversion.

The electric motor, is rated 25VDC, without any information about it's amperage capacity.
It has three thicker wires ( which I believe, are for the 25V input, colored, red, black, and white; while there are four tiny wires(red, blue, yellow, and black), which goes to the steering ECU.

Can someone pls point me to how I can at least, bench test this motor, without the aid of it's ECU?

Here is what I have done so far:
Jumped the black/white thicker wires of the motor, and applied a 48VDC power supply to it, without making any attempt to run.
Because it didn't ran, I thought, hey, maybe I could jumper the tiny black/blue/yellow wire connectors, to mimic the signal communication between the wires and ECU.

Thanks

I have tried several times, to see if I could run the motor, on a bench, without the steering ECU as was in the car.

Umm, I can't see that it would actually be 25v. I bet it's 12v, and tolerant of up to 25v.

...

And, you replaced the power steering on your Corolla, and this is discarded part? And you want to use a power steering motor to power an e-bike? What a journey.

This almost certainly will not work, and if it does you won't want it to.

But, bad ideas make great stories.

I guess find out if it's an AC or DC motor, or, I dunno, is it a servo?

Would recheck if it's a DC or AC motor then..
Are you saying, in theory, this motor from instance can't be used for such a project?

[MattsAwesomeStuff]

"Can't" is a strong word.

It's a poor choice of motors, especially considering all that would be available, even from free junk.

On a desert island with no other options, and unlimited amount of knowledge, yes, a motor can spin, that's what it does.

Three thick wires, four thin wires? Sounds like a 3 phase motor with a resolver

Thanks for your response. I think I'd let this slide away. I have got other 12-24VDC motors that I could use though. Was just asking if this particular one can be made to spin, without the steering ECU

Given the (likely) low power of the motor, the easiest way of driving it would probably be a largeish RC brushless speed controller. Most of them run sensorless (no need for the resolver) which would probably be fine unless you need precise low speed control. If you want/need to use the resolver, and OpenInverter (plus power electronics) will drive it. But seems rather a lot of work!
