Abstract

A molded stator of the present invention includes a stator and a substrate on which a rotor position detection circuit is mounted and has an outer casing formed of a molded resin. The molded stator comprises: a doughnut-shaped lead-wire wiring component (1) that is attached to one axial-direction end of the stator and wires a power supply lead-wire up to a stator winding and a sensor lead-wire up to the position detection circuit; a bush component (6) that is provided on the radial outside of the lead-wire wiring component (1) and leads the power supply lead-wire and the sensor lead-wire to the outside of the molded stator; a power supply lead-wire holding component that is mounted on the bush component (6) and holds the power supply lead-wire; and a sensor lead-wire holding component that is mounted on the bush component (6) and holds the sensor lead-wire. The bush component (6) is connected to a locking portion (26b) for locking the sensor lead-wire holding component and equipped with a projection (17) on the radial outside, said projection (17) being a planar portion that is substantially vertical to the radial direction of the stator.

Description

technical field [0001] The present invention relates to a molded stator, a molded motor and an air conditioner. Background technique [0002] Conventionally, molded motors have been used as fan motors for indoor units and fan motors for outdoor units of air conditioners. In this molded motor, the stator is molded from a molding resin to form an outer shell, and the rotor is freely arranged on the inner peripheral side of the outer shell. A wire lead-out part is attached to the molded motor to lead out the lead wires from the stator or the wiring board to the outside. Furthermore, the wiring lead-out member is integrally molded with a molded resin together with the stator and the wiring member. [0003] However, with such a structure, water tends to infiltrate from the gap or interface between the outer shell of the molded motor and the wire lead-out member or from the gap or interface between the wire lead-out member and the lead wire. Therefore, there has been a problem ...
