Abstract

PURPOSE:To reduce the loss of torque for the subject motor by a method wherein the second rotor is rotated by the eddy current generated by the magnetic flux coming from the first rotor. CONSTITUTION:The supporting plate 23, whereon six flat-plate type coils 24 are arranged at equiangular intervals, is installed on a substrate 1 using a fitting 24. The ring-shaped field magnet 29 having an NS pole which is magnetized at an interval of machine angle 45 deg. on the rotor disk 28 constructed in one body with a rotating shaft 27 rotatably supported by the base plate 1, is installed in concentric circle and the first rotor 30 is constituted. On the upper section of a rotating shaft 27, the second rotor 31 which rotates separately from the first rotor 30 is provided. When a current is applied on a coil 21, the first rotor 30 is rotated by the rotating magnetic field generated by the coil 21. By the rotation of the first rotor 30, the eddy current is generated at the second rotor 31 and the second rotor 31 is also rotated by the eddy current.
