PURPOSE:To reduce the vibration noise of a commutatorless motor by integrating circuit elements, and integrally forming the housing of the IC and a plate of the essential portion of a stator, thereby reducing the variation in a reluctance torque between a rotor magnet and a yoke. CONSTITUTION:A circuit containing case 7a is integrally mounted on a resin plate 7. A drive circuit components watertightly integrated is contained in the case 7a. A terminal piece 7b for connecting the integrated circuit with external wirings 6 is concentrically projected from the opposite yoke side. Thus, the plate 17 can be laid substantially over the entire surface of the plate 7. |
