Abstract: A motor includes a plurality of bus wires of a common phase which are put together before being guided in a common passage to minimize the space arranged to guide the bus wires. Also, the bus wires of a common phase are easily insulated from those of different phases, and an axial height of the motor is reduced. Further, a radial width necessary to guide the bus wires is reduced, and an axial height of the motor including a sensor portion which detects a rotary position of the motor is reduced. Also, the bus wires are easily extended from the armature, and an amount of work required to connect the bus wires and the terminals is reduced. Furthermore, the connection terminal portion does not interfere with the bus wires when they are being guided.

Abstract: In a motor, a raised portion arranged to project toward a rotor magnet is provided on an opposed surface of each tooth portion. This raised portion provided on an opposed surface of each tooth portion. This raised portion is provided at a substantial middle of the opposed surface in a circumferential direction. This allows a waveform of a cogging torque generated by the raised portions and a fundamental of a waveform of a cogging torque generated by slot openings to be substantially in opposite phases. Cogging torque generated by the slot openings can be thereby reduced, because of the cogging torque generated by the raised portion.
