Weber and Coulomb's MX-5

And with the auxiliary battery fixed, it became worthwhile to fix the power steering, again with help from Bladecar.

For some reason I found myself looking at radio controlled hobby motors and found some in-runner motors that spin up to 5000 rpm and are good for about 2 kW. I thought to myself maybe these could be good for driving power steering pumps in conversions where replacing the power steering system with a complete electric system would be too difficult.

Do you think it's possible to use one of these motors:

And one of these speed controllers:

And control the speed of the motor (and therefore power consumption) by making it inversely proportional to the speed of the vehicle?

I have no idea how much power a power steering unit needs, but surely a 1 kW brushless motor is up to the task?

Not really sure Chris. I suspect it might be a bit too high speed and low torque. But mine is current limited to 30 A at 12 V (360 W) so maybe.
