PURPOSE: To make it possible to replace parts having the lives thermally and parts having low pressure resistance and low heat resistance and the like without specially adding attaching members. CONSTITUTION: Of parts constituting a control circuit 21, the parts are separated into a replacement circuit substrate part 21A having the parts requiring replacement and an another non-replacement circuit substrate part 21B. A recess part 22A is provided at a part of a substrate holder 22 for holding the non- replacement circuit substrate part 21B. The recess part 22A is made to be a non-injection part of a synthetic resin 4. The replacement circuit substrate part 21A is contained the recess part 22A. Other parts of a stator core 1 and a winding 2 and the non-replacement circuit substrate part 21B as a part of the control circuit 21, the substrate holder 22 and the like are molded as a unitary body with the synthetic resin 4. Thus, the parts having the low pressure resistance and heat resistance can be replaced. Since the substrate holder 22 of the non-replacement circuit substrate 21B is utilized, a new member is not required. |
