Document Type and Number:
Japanese Patent JP2003284273
Kind Code:
A
Abstract:
To provide a surface-bonded permanent magnet synchronous dynamo-electric motor that can utilize reluctance torque.
The surface-bonded permanent magnet synchronous dynamo-electric motor is provided on the surface of the rotor 20 with at least one pair consisting of an N pole and an S pole of a first permanent magnet 21 at angled intervals relative to the center of the rotor. At least one slit 22 is formed between the center of the rotor and each first permanent magnet 21 extending in the direction of the axis and intersecting in the radial direction; a second permanent magnet 23 is inserted in the slit 22.
