PURPOSE:To improve the workability and the reliability in the termination of a coil by constituting a brushless motor of a wiring board in which terminal parts for connecting the other end of a coil through a bracket and a part for coupling the terminal parts are integrated, and a bracket body made of an insulating material for securing the wiring board. CONSTITUTION:A bracket 7 is composed of a bracketed plate 8, a wiring board 9, and a bracket body 10, and in the wiring board 9, a connection 9g being a ring-shaped conductive path is made inside, and further three pieces of terminal parts 9be, 9de, and 9fe, which project outward from the connection 9g at intervals of about 120 deg., are formed integrally. These terminal parts 9be, 9de, and 9fe are the ones for connecting the other ends 5be, 5de, and 5fe of coils corresponding to each phase, and the central part or its vicinity is made into U-shaped groove where the outside in radial direction is cut off. By this connection and three pieces of terminal parts 9be, 9de, and 9fe, the other ends 5be, 5de, and 5fe of the coils corresponding to each phase are connected in common. |
