Abstract
An AC motor-generator includes a rotor made up of a first inductor core and a second inductor core arrayed in an axial direction of a rotary shaft. A plurality of permanent magnets are arrayed at an interval of 2π in electrical angle of an armature away from each other in the periphery of each of the first and second inductor cores. Each permanent magnet is magnetized in a radius direction of the first and second inductor cores so as to be opposed to a magnetomotive force produced by a field winding, thereby resulting in quick disappearance of the magnetic flux of the field upon disappearance of the magnetomotive force from the field winding.
Claims9
A motor generator comprising:
- an armature including polyphase windings;
- a field core;
- a field winding wound around said field core;
- a pole rotor disposed between said armature and said field core to be rotatable together with a rotary shaft, said pole rotor being made up of a first inductor core and a second inductor core arrayed adjacent each other in an axial direction of the rotary shaft;
- and
- a plurality of permanent magnets arrayed at an interval of 2π in electrical angle of said armature away from each other in each of the first and second inductor cores of said pole rotor in a circumferential direction of the first and second inductor cores, each of the permanent magnets being magnetized in a radius direction of the first and second inductor cores so as to be opposed to a magnetomotive force produced by said field winding.
