Thought I'd add to this thread as its a question I have too for my driving cab.
Picked up a Cruisin World which uses a Happ steering wheel and inside it there's a Rae 3120301 motor. Specs on the body show 90 Volts DC, 1.51 amps.
Has anyone hacked one of these using an AMC 30A8T and 24V power supply? I was going to use something like this: http://www.ebay.com.au/itm/110920245043 , but this is probably going to be overkill, considering the motor is only rated to 1.51A? Is the FF going to be strong using this motor?

Yes it'll all be good.

Thanks for that.
Given that the motor is rated to 90V, should I go for a higher voltage power supply?
Am I right in saying I could cheap out and buy a 2A power supply too, since it won't draw more than 1.5A?

No 24V power supply is lots.

I wouldn't. You have the same motor I'm using and I've measured mine up to 4A depending on which effect is being sent to the wheel. You can measure this on a couple of the pins of the servo amp. I'm not sure how a 2A power supply would work out to be honest but because you haven't got one yet I'd just buy one that I know will work rather then buy twice.
lordsnipe:
No probs .. 6A it is then!
24V 6A power supplies aren't expensive .. just thought given the choice of a higher voltage, less current power supply, would it be more suitable? Seems like 24V and some decent current is plenty.
Cheers.

I've never run into a situation where I have found the ffb to be underpowered. In quite a few cases I turn it down on the software side either through the emulator I'm using or through logitech profiler.
If you've got some cash to burn though pick up one of each and then let me know which one is better :cheers:
