Abstract

Each permanent magnet of a rotor includes: a first and a second linear portion arranged in a circumferential direction and extending from an outer periphery side of a rotor core toward a rotation axis; a third linear portion located between the first and the second linear portion in the circumferential direction and extending obliquely with respect to a radial direction and separately from the rotation axis from an end of the first linear portion closer to the rotation axis; and a fourth linear portion located between the second and the third linear portion in the circumferential direction and extending obliquely with respect to the radial direction and separately from the rotation axis from an end of the second linear portion closer to the rotation axis. Thicknesses of the third linear portion and the fourth linear portion are smaller than thicknesses of the first linear portion and the second linear portion.
