Abstract
A motor may include a rotor; a stator disposed on an outer peripheral side of the rotor; and a resin sealing member covering the stator. The stator may include a stator core; a coil wound around the stator core; and a connector disposed on an outer peripheral side of the stator core. The resin sealing member may include a connector sealing part protruding to the outer peripheral side of the stator core and covering the connector. The connector may include a connection opening through which an external connector is attached and detached, and the connection opening protrudes in an axial direction of the rotor from the connector sealing part and is opened in the direction of the axis.
Claims9
A motor comprising:
- a rotor;
- a stator disposed on an outer peripheral side of the rotor;
- and
- a resin sealing member covering the stator, wherein
- the stator comprises:
- a stator core;
- a coil wound around the stator core;
- and
- a connector disposed on an outer peripheral side of the stator core;
- the resin sealing member comprises a connector sealing part protruding to the outer peripheral side of the stator core and covering the connector;
- and
- the connector comprises a connection opening through which an external connector is attached and detached, and the connection opening protrudes in an axial direction of the rotor from the connector sealing part and is opened in the direction of the axis.
A pump apparatus comprising:
- a motor comprising:
- a rotor;
- a stator disposed on an outer peripheral side of the rotor;
- a resin sealing member covering the stator;
- and
- a cover member disposed on one side of the resin sealing member in the direction of the axis;
- wherein the stator comprises:
- a stator core;
- a coil wound around the stator core;
- and
- a connector disposed on an outer peripheral side of the stator core;
- the resin sealing member comprises a connector sealing part protruding to the outer peripheral side of the stator core and covering the connector;
- and
- the connector comprises a connection opening through which an external connector is attached and detached, and the connection opening protrudes in an axial direction of the rotor from the connector sealing part and is opened in the direction of the axis;
- an impeller attached to a rotary shaft of the rotor penetrating the cover member and protruding to the first side of the cover member in the axial direction;
- the connector includes a connector housing protruding from the connector sealing part to other side in the direction of the axis, the connection opening being provided in the connector housing;
- and
- one of the resin sealing member and the cover member is provided with an engagement projection that protrudes toward the other one thereof, and the other one is provided with a rotational engagement part that is engaged with the engagement projection when the cover member is rotated relative to the resin sealing member around the axis.
