Abstract
PURPOSE: To make small in size and light in weight with a torque increased as well, by such arrangement that, on around the rotating shaft, with a plurality of rotors and stator cores, numbering the same quantity, correspondingly provided, each located position of the stator core coils be made at a different angle in a direction of rotation of the rotating shaft.
CONSTITUTION: The constitution of a rotor 7 is made by magnetic pole units 20 to 23, where a permanent magnet unit 40 to 43 is put between at least a pair of comb- type magnetic poles 30 to 37. And the pole unit 20 to 23 of the rotor 7 is surrounded by a stator core 1 to 4 with a coil 1c to 4c provided to be wound. And a plurality of the rotors 7 are provided on around a rotating shaft 8, with the same numbered stator cores 1 to 4, correspondingly provided, as that of the rotors 7 on around the rotating shaft 8. The position of locating the coil 1c to 2c, installed to said stator core 1 to 2, is made in an arrangement at a different degree of angle in a direction of rotation of the rotating shaft, with respect to the position of locating the coil 3c to 4c, installed to said the other stator core 3 to 4. In this way, an increase of the torque can be made further with a capability provided for miniaturization, weight lightness and thinned type.
