One other thing I failed to mention is that I need a variable speed motor so that the rate of turn can vary inversely with the speed of the vehicle. I don’t want it to turn as fast at higher vehicle speeds since that could create a dangerous situation. This is fairly easily done with the motor...
Thanks for the reply Ted but that power unit is basically what I am using right now except that I put the manifold and pump together with a variable speed motor that peaks at 1750 rpm. The motor that comes with that and other power units like it turn constant speed at typically 3000-5000 rpm...
I am currently in development of a specialized off road low speed hunting vehicle that I hope to put in to low volume production.
This is an electric vehicle so there is no typical power steering pump available for the steering. It is also drive by wire with a joystick controlling the traction...
