1. A motor comprising:
- a stator having a stator core and a stator winding wound on the stator core along a wound surface of the stator core and integrally molded with insulation resin, the integrally molded insulation resin defining a channel;
a rotor provided with a shaft;
a first bearing and a second bearing for supporting the shaft;
a bracket connected to the stator and retaining at least one of the first bearing or the second bearing; and
a solid conductive pin configured to be disposed in the channel of the molded insulation resin for providing a short-circuit between the stator core and the bracket such that a first end of the solid conductive pin bites into the wound surface of the stator core and a second end of the solid conductive pin bites into the bracket,wherein the insulation resin extends from an edge of the wound surface of the stator core such that the solid conductive pin projects toward the bracket from a portion of the edge of the wound surface and a portion of the extended insulation resin.
