Abstract
A motor includes a rotor configured to rotate integrally with a shaft; a stator placed radially outward of the shaft and radially inward of the rotor; and a tubular bushing that is fixed to one end side of the stator and through which the shaft is inserted. The stator includes: a stator core having a tube portion through which the shaft is inserted, and a plurality of tooth portions protruding radially outward from the tube portion; a plurality of coils formed by winding a winding around each of the plurality of tooth portions; and an insulating layer formed by applying an insulating coating to the tooth portions around which the winding is wound. The bushing includes: a fixed portion to be fixed to an inner peripheral surface of the tube portion; and a guide portion that extends axially outward of an end surface of the stator core from the fixed portion and with which a crossover wire (Wc) connecting between the plurality of coils comes into contact.
