Document Type and Number:
Japanese Patent JP2004242378
Kind Code:
A
Abstract:
To provide a high-output motor capable of simultaneously satisfying all of high torque, low electromagnetic noise, low cogging torque, and low eddy current loss.
This motor comprises a cylindrical stator a rotor disposed in the stator, the rotor including a rotor core and a polar anisotropic flux distribution of a plurality of magnetic poles coming into close contact with the outer periphery of the rotor core; and a compound body, constituted of a cylindrical anisotropic rare-earth bonded magnet with recesses on the respective magnetic poles and rare-earth sintered magnets disposed in the recesses.
