Power steering pump run using Electric Motor

I am planning to install a second power steering pump for a Ford Econoline Superduty truck. This pump would run on an electric motor. I was thinking of using valves to bypass the original power steering and use this new pump to pressurize the Power steering fluid.

I wanted to know if anyone had done this earlier or if anyone has any suggestions on how to do it.

The reason for this change is that we are now using a electric motor to drive the truck and do not want the engine to on to just run the power steering pump.

Any suggestion would be helpful. Thanks in advance,

Chet

That could be a "deal killer" unless your truck is plugged in whenever you use it, depending on what you are trying to accomplish. Figure 5-6 horsepower mean, up to 15 hp peak, to run the pump with effectiveness.

Are you trying to be able to switch back & forth from gas to electric?

How in the world did you put an electric motor into a SD ? Pictures ?

Subaru has an electric power steering pump you might be able to get from a junkyard:

Some new GM's like the G6 and Malibu have electric power steering as options.

What about using an additional electric motor to drive the power steering pump as if it was still being driven off a gas engine? Use a sensor to detect wheel movement and speed and only spin the pump if needed.

80 A * 12 V = 960 W. 960 W ~= 1.3 HP (1 HP ~= 750 W).

So an electric power steering pump uses about 1.3 HP + maybe 20% for inefficiency in the alternator. Of course, this is assuming that the power steering pump use 80 A all the time, which I doubt.
