A rotary electromechanical device and a pulley driving system using the rotary electromechanical device

摘要

A rotary electromechanical device of the invention comprises a motor (A3) including a stator (3b) and a rotor (6a), a motor (B4) including a stator (4b) and a rotor (6b), and variable power supplies (2a, 2b) for driving the respective motors (A3, B4) independently of each other, wherein the motors (A3, B4) are arranged in series along the axial direction of a rotary shaft (5). Magnetic poles of the same polarity of the rotors (6a, 6b) are located at the same angular positions around the rotary shaft (5) while magnetic poles (+U1) of the stator (3b) of the motor (A3) and magnetic poles (+U1) of the stator (4b) of the motor (B4) are displaced from each other in the circumferential direction of the rotary shaft (5).
