Next, the O-ring 7 is inserted into the outer peripheral portion of the stator portion, and the circuit board 8 is inserted so as to sandwich the O-ring. In this state, the lead 6-b is fixed to the circuit board by soldering. In addition, the lead wire 6-b is provided with an appropriate flexure, and has a highly reliable structure with no extraordinary flexibility against external vibrations and the like. Finally, the fly cover 10 is inserted into and fixed to the stator and the rotor to complete the assembly. The circuit board 8 receives a force in the direction of the fly cover 10 by the O-ring 7, so that the semiconductor 9 is brought into close contact with the fly cover 10. The fly cover 10 is a die-cast product of Auminium, and has a large heat radiation effect and the semiconductor 9 is sufficiently cooled. In addition, since the terminals of the semiconductor 9 do not use the spring properties of the terminals, the terminals are not stressed and have a highly reliable structure. If the semiconductor 9 is sufficiently cooled, the power supplied to the motor can be increased, and the motor output can be increased in the same shape.
