Title:
EMBEDDED MAGNET-TYPE ROTOR AND ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/029449
Kind Code:
A1
Abstract:
In the present invention, each of the magnetic poles of an embedded magnet-type rotor comprises an iron core on which magnets are arranged, and has a first flux barrier and a second flux barrier respectively provided to the end parts of the magnets with the magnetic pole center therebetween. The first flux barrier includes a first elongated portion that is contiguous with a first base portion and that extends in the circumferential direction from the first base portion toward the magnetic pole center. The second flux barrier includes a second elongated portion that is positioned so as to be spaced from a second base portion with the iron core therebetween and extends in the circumferential direction from the second base portion side toward the magnetic pole center. A magnetic flux bypass portion that connects the outer periphery and the inner periphery of the rotor in the radial direction by means of the iron core is formed between the second base portion and the second elongated portion.
