Abstract

A stationary portion of a motor includes resin bodies including an inner resin portion and an outer resin portion. The inner resin portion is between a tooth and a coil and between the tooth and an insulator. The outer resin portion covers circumferentially outer sides and axially outer sides of the coil. The inner and outer resin portions are continuous with each other through a connecting resin portion. The insulator includes an opening portion extending along circumferential side surfaces of the tooth. The inner resin portion is in contact with the circumferential side surfaces of the tooth and a conducting wire in the opening portion. Heat generated in the coil is transferred to the tooth through the resin body. A path along which the heat is transferred from the coil to the tooth is secured, and dissipation of heat out of the motor is promoted.
