Described is a three-part electric vehicle drivetrain architecture incorporating (1) a hybrid motor assembly incorporating both AC and DC motor architectures to combine high power of the DC motor with the efficiency of the AC motor, (2) a power stage that delivers the precise amount of the electrical energy to the motors, and (3) a microprocessor-based control system that performs all the control functions of the drivetrain. In the hybrid AC/DC motor assembly, the DC motor and one AC motor are arranged back to back with their driveshafts mechanically coupled. In this arrangement, the motors are integrated into one unit by removing back/front plates and replacing individual shafts with a single shaft. Mechanical connection of such a motor assembly to the wheels is performed via the conventional transmission/driveshaft. |
