Two AC motors on one VFD

You can connect two AC motors to the same VFD - at least in the industrial world. I can think of applications where we use up to 4 motors driven by one VFD. If you want the motors to share a load, it helps that they are matched as closely as possible.

Two motors run from one VFD would give you about the same torque if they are well matched. You'd have to do some testing to check if using one motor for each of the rear wheels, driven by the same VFD, would give you acceptable results.
