A brushless direct current (BLDC) motor that generates electrical energy (AC voltage) while operating as a motor. The motor is configured with a dual purpose stator assembly wherein one segment of the stator assembly includes coil windings to produce the rotary force (torque) in the rotor and the other segment of the stator assembly includes coil windings to generate electrical energy. The stator windings for producing torque are electrically connected through commutation control circuitry to a DC supply source, and the stator windings for generating electrical energy are connected to a load or to an energy storage system. Thus, the embodiment offers a novel means for generating electrical energy in the conventional BLDC motors. Because the motor can generate electrical energy while operating as a motor, it can effectively serve as a powertrain in electric vehicles, whereby the electrical energy it generates can be used to extend the vehicles' drive range.
