Abstract

A motor includes magnets arranged in a circumferential direction and a rotor core holding the magnets. The magnets include two or more magnet pairs with a pair of long sides and a pair of short sides. The pair of long sides have mutually different polarities. Magnetic poles of the same polarity are positioned circumferentially opposite to each other. A corner lying on a short-side side closer to the central axis and on a side closer to the other magnet of the magnet pair is located in a separate flux barrier in the rotor core. End points of a boundary between each magnet and a corresponding one of the flux barriers lie on one of the pair of long sides which includes the corner and on one of the pair of short sides which includes the corner or another one of the pair of long sides.
