Abstract

PURPOSE:To improve the assembling property of a brushless motor by mounting fixedly a circuit board on which a motor driving electronic circuit and a rotary position detecting field detecting element are integrally mounted to the back surface of a stator yoke of a motor body, thereby reducing the number of the ends of wires. CONSTITUTION:Small holes are opened at the prescribed position in the surface of a stator yoke 3, magnetic field detecting elements 4, 4', 4'' are respectively inserted into the holes, the elements 4, 4' 4'' are arranged at the positions confronting the pole surfaces of a rotor magnet 1, and a circuit board 55 is exposed fixedly to the back surface side of a stator yoke 3. The elements 4, 4', 4'' are integrated fixedly to the back surface of the board 55, a circuit pattern conductor is formed on the front surface of the board 55, and integrated circuits 70, 71 of a motor driving electronic circuit are placed fixedly on the prescribed position of the front surface of the board. The ends of a stator coil 2, an FG coil 35' and the elements 4, 4', 4'' are connected to the integrated circuits 70, 71 with wiring pattern conductors on the board 55.
