DYNAMO-ELECTRIC MACHINE

摘要

A core (12) constituting the stator or rotor of an dynamo-electric machine is formed, at least partially, of an integrated composite material of magnetic powder and an insulating member. Since the composite material of magnetic powder and an insulating member provides a magnetic body also serving as an insulator, a magnetic circuit restricted in eddy current loss can be formed without requiring a laminate structure. In the inventive core (12), reluctance and variation thereof can be reduced as compared with a conventional one. In an dynamo-electric r machine provided with such a core (12), the output can be increased while suppressing cogging torque as compared with an dynamo-electric rotating machine provided with a conventional core.
