Abstract:
A motor includes a stator to which a substrate can be stably secured without increasing the size of the substrate. An air-conditioning apparatus includes the motor. At an end portion of the stator in the axial direction thereof, a substrate on which electronic components are mounted is provided. The stator includes: a stator core formed by stacking electromagnetic steel sheets, and including a plurality of teeth; insulators provided on the stator core; and a wire wound around the teeth, the teeth being coated with the insulators. The insulators have outer walls provided on respective core backs of the stator core. In a linearly developed state of the stator, where of the teeth, an outermost tooth is a first tooth, a tooth adjacent to the first tooth is a second tooth, another tooth adjacent to the second tooth is a third tooth, another tooth adjacent to the third tooth is a fourth tooth, and another tooth adjacent to the fourth tooth is a fifth tooth, the outer walls of the first, third and fifth teeth include respective substrate attachment pins for use in attachment of the substrate, and the outer walls of the first tooth include respective power terminals for use in supplying power to the wire.
