It is an object of the present invention to provide an effective technique for easily installing many turns of a coil winding on the stator body. According to the invention, method of manufacturing a motor is provided. The motor may include a stator body (100), field cores (110,120), pole pieces (112,122), coil receiving parts. The method may include the steps of bending the pole pieces (112,122) away from the coil receiving parts, inserting the tied coils (140,150) into the coil receiving parts and bending the pole pieces bent away from the coil receiving parts toward the coil receiving parts, thereby retaining the coils in the coil receiving parts by the pole pieces. Because the pole pieces are once bent away from the coil receiving parts and then, the tied coils are inserted into the coil receiving parts, it is not necessary to retain each turn of the coil winding and therefore, number of turns of the coil winding is not restricted by the length of the pole pieces. As a result, high motor output can be ensured without uselessly upsizing the motor.
