PURPOSE:To readily and inexpensively seal the outer periphery of a connector by impregnated varnish between the outer periphery of the connector and a collar at the step time of impregnating a stator with the varnish. CONSTITUTION:A stator 2 sealed with a can 3, a frame 1 and a collar 4 is impregnated with varnish. The varnish is impregnated from a gap A between the frame 1 and the outer periphery of the stator 2 to a connector 8 side. Here, the varnish is impregnated from the coil 9 to improve the heat dissipating effect, adhered also to the surface of the stator 2 and the coil 9, but this impregnating amount is selected in an adequate amount, the varnish is impregnated to the stator 2, and simultaneously impregnated to the engaging portion 4a of the collar 4 with the connector 8. |
