Title:
AC INDUCTION MOTOR STRUCTURE
Document Type and Number:
Japanese Patent JPH01190242
Kind Code:
A
Abstract:
PURPOSE: To reduce the hysteresis loss by forming inner and outer synchronous rotor poles and a synchronous rotor pole connector, so as to surround an inner cylindrical surface of a hollow cylindrical inductor and an outer cylindrical surface of a hollow cylindrical stator core. CONSTITUTION: A synchronous rotor means 1 includes a cylindrical inner polar member 2 and a cylindrical outer polar member 3, and the members are concentrically mounted on an annular pole connecting means 4. An induction rotor means 8 includes a hollow cylindrical inducting means 9. A stator means 15 includes a hollow cylindrical stator core 16 and a stator positioning means 17. Arbitrary excitation of the magnetic field is obtained by a stationary magnetic field winding 21 including a mounting means 23 to be mounted on a conductor 22 and the stator means 15. The synchronous rotor means 1 is rotated at the synchronous velocity determined by the frequency of an AC energy source and the number of magnetic field focusing members 7.
