Title:
SWITCHED RELUCTANCE MOTOR
Document Type and Number:
Japanese Patent JP2016019370
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a switched reluctance motor whose efficiency can be prevented from degrading.SOLUTION: In an SR (Switched Reluctance) motor 1, a rotor 2 is rotated around a rotation axis α. In permanent magnets 331, 332, two poles are arranged in a radial direction of the rotor 2. Stator teeth 32A-32F extend from the outside to the inside in the radial direction. A back yoke 35 is arranged so as to cover the radial outside of a stator core 31. A teeth group A1 is composed of stator teeth 32A-32C continued in a peripheral direction of the rotor 2. A teeth group B1 is composed of stator teeth 32D-32F continued in the peripheral direction of the rotor 2. The permanent magnets 331, 332 are in contact with an outer circumferential surface of the stator core 31 and an inner circumferential surface of the back yoke 35. The permanent magnets 331, 332 are respectively arranged in the radial outside of the teeth group A1 and the radial outside of the teeth group B1. A direction of a pole of the permanent magnet 332 is opposite to a direction of a pole of the permanent magnet 331.SELECTED DRAWING: Figure 1
