Abstract

PURPOSE:To smoothly rotate a motor by imparting a delaying property to the magnetic attraction force of a rotor magnetic material. CONSTITUTION:A mixture 6 of magnetized powder magnetic material and viscous fluid is filled in the annular groove 3 of a rotor body 2 of nonmagnetic material, a hermetical seal is maintained with sealing rings 7, 8, which are associated and clamped with screws 9, 9'. A plurality of stationary cores 10 and stationary coils 11 are radially arranged at an adequate interval from a rotor body 2 at the position faced with the annular groove 3 at the side of nonhysteresis material 5, and are secured to a motor body 12. When a revolving magnetic field is produced with the current of the coil 11, the mixture 6 and hysteresis material 5 are attracted by the magnetic field, and the rotor body 2 is rotated in the same direction.
