Abstract
A rotary electromechanical device includes a first motor including a first stator and a first rotor, a second motor including a second stator and a second rotor, and variable power supplies for driving the respective motors independently of each other, The motors are arranged in series along the axial direction of a rotary shaft. Magnetic poles of the same polarity of the rotors are located at uniform angular positions around the rotary shaft while magnetic poles of the stator of the motor and magnetic poles of the stator of the second motor are displaced from each other in the circumferential direction of the rotary shaft.
