A control system for an electric motor having an integral flywheel rotor. The motor includes a stator mounted co-axially with the engine crankshaft and a rotor surrounding the stator. A sensor is positioned near the rotor for sensing its rotational speed. The sensor is coupled to a controller. The controller is operable to deliver an output signal to the stator to start the internal combustion engine. While the engine is starting, the processor steps the starter motor from a low speed to a high speed. Once the engine has started and is rotating at a speed greater than a trigger speed, the processor delivers another output signal such that the motor is commutated at a speed that is less than the speed of the rotor to generate a speed slip. By commutating the motor in this manner, it acts as a generator. The speed slip is regulated when the motor is generating electric power so that the motor produces a constant output voltage.

1. A control system for an electric motor having a stator and an integral flywheel-rotor with a plurality of position indicators, the system comprising:a sensor that generates a signal based on the movement of the position indicators of the rotor; and a controller coupled to the sensor to receive the signal and operable to deliver an output signal to the stator such that the motor is stepped from a low rotational speed to a high rotational speed in a series of increments, wherein the controller checks the rotational speed of the rotor before stepping the motor to the next increment.
