MOTOR

摘要

A rotating section of the motor includes a plurality of magnets which is arranged in a circumferential direction, a rotor core having an outer peripheral surface which comes into contact with the radially inner surfaces of the magnets, and a magnet holder which holds the magnets between the magnet holder and the rotor core. The magnet holder has a columnar portion axially extending between adjacent magnets among the plurality of magnets, and a wall surface spreading in a circumferential direction from the columnar portion. The wall surface is in contact with the surface arranged radially outer than a circumferential end face of the magnet. Further, the circumferential end face on at least one side of the magnet faces the columnar portion with a gap interposed therebetween in the circumferential direction. For this reason, even if some of the magnets are formed larger than a design dimension, deformation of the columnar portion by the magnet does not easily occur. Therefore, an obstacle in disposing of another magnet also does not easily occur.
