Abstract
The stator includes a stator core having a first tooth and a second tooth adjacent to each other, a coil having a first winding portion wound around the first tooth and a second winding portion wound around the second tooth, a resin chip disposed in in a gap between the first winding portion and the second winding portion, and a molding resin covering the stator core, the coil, and the resin chip.
Claims16
A stator comprising:
- a stator core having a first tooth and a second tooth adjacent to each other;
- a coil having a first winding portion wound around the first tooth and a second winding portion wound around the second tooth;
- a resin chip disposed in in a gap between the first winding portion and the second winding portion;
- a molding resin covering the stator core, the coil and the resin chip, and
- a wiring component on which a lead wire is wired, the wiring component being attached to the stator core,
- wherein the wiring component has an opening having a size allowing the resin chip to pass therethrough.
A motor comprising a stator and a rotor disposed in inside the stator, the stator comprising:
- a stator core having a first tooth and a second tooth adjacent to each other;
- a coil having a first winding portion wound around the first tooth and a second winding portion wound around the second tooth;
- a resin chip disposed in in a gap between the first winding portion and the second winding portion;
- a molding resin covering the stator core, the coil and the resin chip, and
- a wiring component on which a lead wire is wired, the wiring component being attached to the stator core,
- wherein the wiring component has an opening having a size allowing the resin chip to pass therethrough.
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 stator and a rotor disposed in inside the stator,
- wherein the stator comprises:
- a stator core having a first tooth and a second tooth adjacent to each other;
- a coil having a first winding portion wound around the first tooth and a second winding portion wound around the second tooth;
- a resin chip disposed in in a gap between the first winding portion and the second winding portion;
- and
- a molding resin covering the stator core, the coil and the resin chip, and
- a wiring component on which a lead wire is wired, the wiring component being attached to the stator core,
- wherein the wiring component has an opening having a size allowing the resin chip to pass therethrough.
A method of manufacturing a stator, the method comprising the steps of:
- preparing a stator core having a first tooth and a second tooth adjacent to each other;
- winding a first winding portion of a coil around the first tooth and winding a second winding portion of the coil around the second tooth;
- attaching a wiring component on which a lead wire is wired to the stator core;
- supplying a resin chip into a gap between the first winding portion and the second winding portion, and
- integrally molding the stator core, the coil and the resin chip using a molding resin,
- wherein the wiring component has an opening having a size allowing the resin chip to pass therethrough.
