Abstract
A motor includes a rotor having a shaft, a stator provided so as to surround the rotor, a first bearing and a second bearing rotatably supporting the shaft and disposed at a distance from each other in an axial direction of the shaft, a molded resin part covering the stator and having a bearing support part supporting the first bearing, a bracket attached to the molded resin part, supporting the second bearing, and having conductivity, and a conductive member provided in contact with both of the bearing support and the bracket.
Claims14
A motor comprising:
- a rotor having a shaft;
- a stator provided so as to surround the rotor;
- a first bearing and a second bearing rotatably supporting the shaft and disposed at a distance from each other in an axial direction of the shaft;
- a molded resin part covering the stator and having a bearing support part supporting the first bearing;
- a bracket attached to the molded resin part, supporting the second bearing, and having conductivity;
- and
- a conductive member provided in contact with both of the bearing support part and the bracket,
- wherein the bearing support part of the molded resin part has an outer circumferential surface having an annular shape about a central axis line of the shaft;
- and
- wherein the conductive member has:
- a first annular part contacting the outer circumferential surface of the bearing support part;
- and
- a strip-shaped connecting part extending from the first annular part to the bracket and contacting the bracket.
An air conditioning apparatus comprising:
- an outdoor unit having a first fan, and a first motor to drive the first fan;
- an indoor unit having a second fan, and a second motor to drive the second fan;
- and
- a refrigerant pipe connecting the outdoor unit and the indoor unit,
- wherein at least one of the first motor and the second motor comprises:
- a rotor having a shaft;
- a stator provided so as to surround the rotor;
- a first bearing and a second bearing rotatably supporting the shaft and disposed at a distance from each other in an axial direction of the shaft;
- a molded resin part covering the stator and having a bearing support part supporting the first bearing;
- a bracket attached to the molded resin part, supporting the second bearing, and having conductivity;
- and
- a conductive member provided in contact with both of the bearing support part and the bracket,
- wherein the bearing support part of the molded resin part has an outer circumferential surface having an annular shape about a central axis line of the shaft;
- and
- wherein the conductive member has:
- a first annular part contacting the outer circumferential surface of the bearing support part;
- and
- a strip-shaped connecting part extending from the first annular part to the bracket and contacting the bracket.
