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?
