mide, sure you can invert DC to AC but that is not efficient, maybe 85%, much power loss in the form of heat. DC motors have been around for a long time, fact is, cars have DC motors, no inversion. 12v battery in series with another is 24v, one more in series makes 36v, and so on and so on. dc motors are very efficient, very high torgue dynamo's where you get 100 torque at o rpm. trains and elevators have DC motors in them for years, very powerful at low speed any can have RPMs limited only by inertia breaking the rotor to pieces.
