PURPOSE:To enable to obtain characteristics of different torque properties by providing two types of rotors at both sides of a stator core. CONSTITUTION:A stator core 12 having an axial air gap is provided between a pair of opposed rotors 10 and 11. The first motor has a stator winding 13 and a shaft 14 press-fitted into the rotor 10, and bearings 15, 16. The second motor has a stator winding 17 provided on the core 12, and a stop shaft 18 secured with the rotor 11 to the shaft 14. The rotor 10 has a core squirrel-cage type, and the rotor 11 is of coreless lump. When the stator winding 13 or 17 of the second motor is energized, torque is generated at the corresponding rotor 10 or 11. |
