Abstract
A motor includes a rotor with a shaft, a stator, first and second bearings supporting the shaft, a bus bar assembly holding the second bearing, a circuit board, a sensor magnet fixed to the shaft, and a rotation sensor which is attached to the circuit board and faces a direction. The bus bar assembly includes a bus bar and a bus bar holder. The bus bar holder includes a cylindrical main body portion including an opening at a second side. The bus bar includes a coil connection portion that protrudes from an inner surface of the main body portion and is electrically connected to a coil of the stator. The end of the second side of the coil connection portion is located at a second side ahead of a surface of a first side of the circuit board.
