DYNAMO-ELECTRIC MACHINE COMPRISING FIELD CONTROL COIL

Title:

DYNAMO-ELECTRIC MACHINE COMPRISING FIELD CONTROL COIL

Document Type and Number:

WIPO Patent Application WO/2002/080338

Kind Code:

A1

Abstract:

A dynamo-electric machine is so constituted as to easily change the characteristics of a dynamo-electric machine comprising permanent magnets and comprises a field control coil so as to adopt the dynamo-electric machine comprising common components to various applications. In this dynamo-electric machine, the field control coil is so adopted to a field which a magnetic pole and an iron pole supply to core teeth so as to superpose magnetic fluxes of different strengths. A permanent magnet is disposed in a recess of the inner peripheral face of a yoke to form a magnetic pole by a permanent magnet, and an iron pole by a yoke section between adjacent permanent magnets, and the inner peripheral face of the permanent magnet is located below the yoke section, thereby differentiating the strengths of magnetic fluxes.
