METHOD FOR MANUFACTURING MOTOR AND METHOD FOR JOINING MOTOR
A method is for manufacturing a brushless motor including a magnet surrounding a rotational shaft, a cylindrical coil including wires being wound, and a motor case accommodating the magnet and the coil. The coil has multiple phases. The wires each corresponding to one of the phases are shifted from one another in a rotation direction of the rotational shaft. The wires include a first wire for a first phase and a second wire for a second phase adjacent to the first phase in the rotation direction. The first wire is colored differently from the second wire. The coil has a color boundary between the wires for the first and second phases adjacent to each other in the rotation direction. The color boundary is aligned with a mark in the motor case to fix the coil to the motor case.
