[QUOTE="Terryl, post: 1024637, member: 369937"] I would not do this, a DC motor rated at 36 volts DC has a starting load maximum rating, (starting torque) this is called a locked rotor condition, the motor at a dead stop has a very high torque load on it when starting up, (rotor is not moving, load is at a dead stop) if the DC starting voltage is too low the resulting DC current draw may be too high for the DC supply circuit, this may also cause overheating in the motor. The internal DC resistance of the motor does not change, this is just a big resistor under a locked rotor state, the design of the motor calls for 36 volts DC at X amps to overcome this state, reduce the DC voltage and the current requirement to over come the locked state (starting torque) may do some damage to something.
