Abstract
According to one aspect of the present disclosure, a rotor includes a plurality of permanent magnets and a support supporting the permanent magnet. The support includes at least one of an outside support fixed to a radial outside of the outer cores to circumferentially support an end face of the permanent magnet from both sides and an inside support fixed to a radial inside of the outer cores to circumferentially support the end face of the permanent magnet from both sides. Each of the outer cores includes an opposite face parallelly opposed to the end face of the permanent magnet in the circumferential direction. The outside support and the inside support each includes a support face circumferentially supporting the end face. The support face is disposed on a side closer to a center line of the permanent magnet than the opposite face in the circumferential direction.
