Title:
ROTOR, AND ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/196609
Kind Code:
A1
Abstract:
At least one of a plurality of magnetic poles (36) includes a first magnetic pole (36) configured from a plurality of permanent magnets (34) arranged in a circumferential direction. A straight line parallel to the magnetization direction of each permanent magnet (34) at both ends, in the circumferential direction, of the first magnetic pole (36) is inclined relative to a magnet centerline (35) of said permanent magnet (34), and in comparison with the magnet centerline (35) is inclined in a direction that approaches a magnetic pole centerline (37) of the first magnetic pole (36) with increasing distance from the center of the permanent magnet (34) toward the radially outer side thereof. An angle between the straight line parallel to the magnetization direction of each permanent magnet (34) at both ends, in the circumferential direction, of the first magnetic pole (36) and the magnet centerline (35) of said permanent magnet (34) is greater than 0° and less than 90°.
