Abstract:
To provide a pump driving motor for a pump device which ensures insulation between a charge part and a non-charge metal part, is inexpensive, improves a temperature rise performance and obtains high reliability.SOLUTION: A pump device comprises: a pump driving motor; a pump part which performs a pump operation by rotating an impeller which is provided within a casing, by means of the pump driving motor; and a control unit for controlling the pump part by shifting a rotation speed of the pump driving motor. In the pump device, insulation between a charge part and a non-charge metal part is ensured by applying a silicone mixture onto a stator coil of the pump driving motor, and the stator coil is pressed to a closed axial side face of a motor housing.SELECTED DRAWING: Figure 6
