Title:
ROTATING ELECTRIC MACHINE ROTOR AND ROTATING ELECTRIC MACHINE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2018/159181
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve demagnetization resistance when a plurality of permanent magnets are arranged, while maintaining high torque performance of a motor. The rotating electric machine rotor according to the present invention forms a first space for housing a first magnet and a second space for housing a second magnet, wherein: a bridge width that becomes the narrowest portion between the first space and the outer circumference of a rotor core is larger than a bridge width that becomes the narrowest portion between the second space and the outer circumference of the rotor core; and the second magnet is arranged so that an outermost part of the second magnet is located on the inner side than an innermost part of the first magnet.
