Title:
RELUCTANCE MOTOR
Document Type and Number:
Japanese Patent JP3705450
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a rigid reluctance motor having high salient pole ratio, high motor efficiency and simple structure which can withstand against high speed rotation by laminating sintered planar members composed of same metal powder composite material where ferromagnetic part and nonmagnetic part coexist thereby constituting a rotor core.
SOLUTION: A rotor core is formed by laminating thin plates 17 composed of a sintered composite material of pure iron powder and SUS 304 powder, for example, where a sintered part of ferromagnetic metal powder composing a ferromagnetic part 11 is jointed integrally with a sintered part of nonmagnetic metal powder composing a nonmagnetic part 18. The rotor core 15 is secured to a shaft 14 thus forming a rotor 1. This structure realizes a rigid reluctance motor having high salient pole ratio, high motor efficiency and simple structure which can withstand against high speed rotation.
