Abstract:
PURPOSE:To perform two different functions with a motor assembly by winding two stator coils on one stator of generally Z shape and disposing the two rotors oppositely to each other. CONSTITUTION:A stator 1 forming generally in Z shape is prepared, and separate stator coils 5, 7 are wound at the sides 6, 8 of both sides. Two pairs of poles 2a, 2b and 3a, 3b are formed at the ends of both sides and at the center 4 of the stator, and separate permanent magnets 2, 3 are respectively disposed. In this manner, two drive shafts 2C, 3C are driven with one assembly, thereby reducing the size and weight of the motor.
