Title:
ROTOR OF RELUCTANCE MOTOR
Document Type and Number:
Japanese Patent JP2017063545
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress wind noise when the rotor of a reluctance motor rotates, while suppressing reduction of the output torque and efficiency.SOLUTION: A rotor 4 of a reluctance motor includes a rotor core 42 where a cylindrical inner magnetic part 43 and a protrusion protruding therefrom to the radial outside are molded integrally. The protrusion includes a salient pole 44 of magnetic substance, and a non-magnetic substance part 45 formed between salient poles 44, 44 adjoining in the circumferential direction. In the outer peripheral surface of the rotor core 42, a slit 46 is provided between the salient pole 44 and non-magnetic substance part 45, and the circumferential width d of the slit 46 is narrower than the circumferential width W of the salient pole 44.SELECTED DRAWING: Figure 2
