- the lead wire lead-out component 2 is pushed radially outward from the center of the stator 10 by the molding pressure. Therefore, the lead wire lead-out component 2 is maintained in its position without contacting the stator core 82, and each lead wire is not fixed in contact with the lead wire lead-out component 2 at the portion where each lead wire comes into contact. There are no voids. Therefore, water that has entered from the gap or interface between the lead wire lead-out component 2 and the mold resin does not travel through the gap between the lead wires and reach the substrate 11. As a result, the quality of the stator 10 can be improved.
- This installation part is, for example, a stepped part having an outer diameter larger than the inner diameter dimension of the stator core 82, a plurality of claws extending in a projecting manner from the opening installation surface of the mold core part to the stator 10 side, A plurality of protrusions that extend from the bracket installation surface near the die core part and are not connected to the inner diameter of the stator core 82.
- stator 10 is supported by the mold installation portion, there is no need to support the outer peripheral portion of the stator 10 with a mold as a regulating member during molding. Therefore, no boundary surface between the stator core 82 and the mold resin is formed on the outer periphery of the mold stator 60.
- the protrusions formed on the side of the insulating inner wall 83b opposite to the connection side are the stator cores 82. It is no longer exposed to the inner diameter side, and the effect of suppressing water ingress can be further enhanced.
- a rotor shaft 72, a waterproof cap 71, and an E ring 73 are assembled to the mold stator 60 using a bracket 74.
- the waterproof cap 71 is for preventing water from entering between the shaft 72 and the bracket 74.
- Step 1 The stator 10 is manufactured.
- the lead wire wiring assembly 40 and the lead wire wiring component 1 are manufactured.
- Step 2 Winding 84 is applied to the stator 10.
- the power supply lead wire 8 is wired to the lead wire wiring component 1.
- the core wire 8a of the power supply lead wire 8 is routed to the core wire holding portion 1m.
- the power supply lead wire holding component 4 is manufactured.
- Step 3 Assemble the power supply lead wire holding component 4 to the lead wire wiring component 1.
- the substrate 11 is manufactured.
- Step 4 The substrate 11 is assembled to the lead wire wiring component 1.
- Step 5 Assemble the sensor lead wire holding component 5 and the lead wire holding component 3 to the lead wire wiring component 1.
- Step 6 The lead wire wiring component 1 is assembled to the stator 10, the pin 81 coming out from the mounting leg 1b of the lead wire wiring component 1 is heat-welded, and the terminal 12 of the stator 10 and the core wire 8a are spot welded. .
- Step 7 The stator assembly 30 is molded to manufacture the mold stator 60. In addition, the rotor and the bracket 74 are manufactured.
- Step 8 A mold motor 70 is manufactured by assembling a rotor or the like to the mold stator 60.
- FIG. 22 shows an air conditioner 100 incorporating a molded electric motor 70 according to an embodiment of the present invention.
- the air conditioner 100 includes an indoor unit 200 and an outdoor unit 300 connected to the indoor unit 200.
- the indoor unit 200 and the outdoor unit 300 are provided with a molded electric motor 70 as a drive source for the blower.
- a plurality of mounting legs 61 (see FIG. 19) extending from the outer peripheral side of the mold stator 60 to the radially outer side are used.
- the mold motor 70 as a motor for a blower that is a main part of the air conditioner 100, the ingress of water into the stator of the motor for the blower is suppressed, and the air conditioner 100 with good quality at low cost. Can be obtained.
- the shape of the lead wire holding portion 9 is not limited to the illustrated example, and is formed integrally with the lead wire wiring portion 1a, and the sensor lead wire 7 and the power supply lead wire 8 are fixed to the lead wire wiring portion 1a. Any shape can be used as long as it can be used. Further, in the present embodiment, the lead wire holding component 3 is fixed to the lead wire wiring component 1 by inserting two claws into the two insertion openings 9f and locking them, but the lead wire holding component 3 As long as the structure is assembled to the lead wire wiring component 1 with a single touch, it may have any shape.
- one end surface of the lead wire holding component 3 is fixed to the lead wire wiring portion 1a, and a nail formed on the other end surface of the lead wire holding component 3 is inserted into the insertion hole of the lead wire wiring portion 1a to be locked. It may be a structure.
- the substrate 11 is held only by the lead wire wiring component 1, and the sensor lead wire 7 and the power supply lead wire 8 that are lead wires. Is held by the lead wire wiring component 1.
- the lead wire lead-out component when the lead wire lead-out component is separated from the lead wire lead-out component, the lead wire is held only by the lead wire lead-out component. Therefore, when the lead wire is subjected to a load in the manufacturing process, there is a problem in that stress is applied to the board solder portion connected to the end of the lead wire, and the electric motor may become inoperable.
- the lead wire is held by the lead wire wiring component 1. Therefore, even when the lead wire connected to the stator assembly 30 is pulled, it is possible to suppress a load from being applied to the solder portion of the substrate 11. As a result, the quality can be further improved as compared with the prior art. In addition, since the generation of stress on the solder portion of the substrate 11 can be suppressed, there is no need to hold the lead wire lead-out component 2 that collects the lead wires, the manufacturing process is simplified, and the component shape of the lead wire wiring component 1 is reduced. Simplification and material cost reduction can be achieved. In addition, the sensor lead wire 7 which is a part of the lead wire is held by the lead wire holding portion 9 to prevent movement of the sensor lead wire 7 due to resin pressure during molding, particularly movement in the rotation direction. Can be improved.
- the stator of the electric motor includes a lead wire holding component 3 that is assembled to the lead wire wiring component 1 and holds the lead wire.
- a lead wire holding component 3 that is assembled to the lead wire wiring component 1 and holds the lead wire.
- stator of the electric motor includes a lead wire lead-out component 2 that leads out the lead wire held by the lead wire wiring component 1. Thereby, the position shift of the power supply lead wire 8 resulting from the pressure of the mold resin at the time of molding can be suppressed.
- the lead wire lead-out component 2 is arranged at a certain distance from the lead wire holding component 3. As a result, the intrusion path between the lead wire lead-out component 2 and the lead wire holding component 3 is blocked, and the water penetration resistance can be improved.
- the mold motor 70 which is the electric motor according to the present embodiment uses the mold stator 60, the quality can be improved. Moreover, since the air conditioner 100 which concerns on this Embodiment has mounted the mold motor 70 in the air blower, improvement in quality can be aimed at.
- the present invention is useful for a stator of an electric motor that drives a load, an electric motor, and an air conditioner.
