Abstract
An electric-motor-powered drive for providing increased output torque within a predetermined space envelope. A pair of electric motors are disposed in end-to-end relationship with their respective output drive shafts in opposed, coaxial relationship. A coupling member extends between the respective motor output shafts to mechanically couple them together for joint rotation in the same direction of rotation and at the same rotational speed. The control circuit for one of the motors includes an inverter to cause the output shaft of the one motor to rotate in the opposite direction from that of the other motor so that torque at the output of the combined motors at the coupling member is the sum of the torques of each of the individual motors
