PURPOSE:To generate rotary torque and control speed by controlling the voltage of controlling winding by a mechanism wherein the controlling winding is wound at the stator side, a commutator and a brush are removed and a rotor is formed in a twisting raising-shaped salient-pole rotor. CONSTITUTION:A stator 1 consists of a cylindrical core 3 which laminating plates are laminated in the axial direction and eight laminated secondary yokes 5 penetrating a through hole 4 at the outside of the core, primary winding 7 generating a revolving magnetic field is wound in a slit 6 at the inside, and annular secondary winding 8 generating a shifting magnetic field in the axial direction is wound at the outside of the primary winding, being distributed in the axial direction among the laminating plates of the cylindrical core 3. A rotor 2 is a single-pole type rotor on which laminating plates are laminated, formed in such a manner that laminating cores 10 are inserted into upper and lower through holes 9, are twisted at 90 deg. and are a twisting raising shape, and fixed to a shaft 11. Thus, structure is simplified, and speed can be controlled in high reliability. |
