Abstract

The present invention is a molded stator including a stator and a substrate. The molded stator includes: a donut-shaped lead-wire wiring component that wires power-supply lead wires to a winding wire of the stator and that wires sensor lead wires to the position detection circuit; a lead-out component that leads out the power-supply lead wires and the sensor lead wires to outside of the molded stator; a power-supply lead-wire holding component that holds the power-supply lead wires; and a sensor-lead-wire holding component that holds the sensor lead wires. The lead-out component is connected to a latching part that latches the sensor-lead-wire holding component and includes projections as plane parts that are substantially perpendicular to a radial direction of the stator on the radially outer side.

First claim

The invention claimed is:

1. A molded stator including a stator and a substrate having a position detection circuit of a rotor mounted thereon and an outer frame thereof being formed from mold resin,
the molded stator comprising:
a donut-shaped lead-wire wiring component that
is attached to an end of the stator in the axial direction,
is configured to wire power-supply lead wires to a winding wire of the stator, and
is configured to wire sensor lead wires to the position detection circuit; and

a lead-out component that
is provided on a radially outer side of the lead-wire wiring component and
leads out the power-supply lead wires and the sensor lead wires to outside of the molded stator, wherein

the lead-out component includes a projection that has plane parts, on the radially outer side, that are substantially perpendicular to a radial direction of the stator, and
the lead-wire wiring component includes a plurality of mounts located on a radially inner end of an annular surface of the lead-wire wiring component on a side of the lead-wire wiring component opposite to the stator, the mounts extending in a trapezoidal shape toward the side opposite to the stator.

2. The molded stator according to claim 1 , wherein
the lead-wire wiring component includes a plurality of attachment legs for attaching the lead-wire wiring component to the stator on an outer circumference thereof,
each of the attachment legs includes a hole through which a fixing pin provided in the stator is inserted, and
among the plurality of attachment legs, two attachment legs provided in the vicinity of both ends of the lead-out component respectively include a wall part.

3. The molded stator according to claim 2 , wherein the plane parts are provided at a position away from the wall part.

4. A molded electric motor that uses the molded stator according to claim 1 .

5. An air conditioner that includes the molded electric motor according to claim 4 incorporated therein as an electric motor for an air blower.

6. The molded stator according to claim 1 , wherein
the lead-wire wiring component includes
at least one substrate holding unit on a radially inner side of the lead-wire wiring component, the at least one substrate holding unit is adapted to attach to the substrate.

7. The molded stator according to claim 2 ,
wherein the wall part is disposed at a radially outer end of the attachment leg, and
wherein the wall part projects in the direction that is substantially perpendicular to the radial direction of the stator.
