Problems solved by technology

[0004] In the method described in Patent Document 1, when manufacturing a motor in which two Y wires are connected in parallel, when winding the stator core, when the end side of the winding is hung on the power supply terminal, the winding may be damaged. slack, and causes the winding to unwind
As a result, the stator core comes into contact with the winding, making it impossible to ensure the insulation state of the winding and the stator core

Embodiment approach 1

[0017] figure 1 It is a perspective view showing a configuration example of a stator (hereinafter, simply referred to as stator 100 ) of the electric motor according to Embodiment 1 of the present invention. figure 2 It is a plan view showing a state in which the stator 100 is reversely bent. image 3 It is an explanatory diagram for explaining the winding order of the stator 100 . Figure 4 is will be with image 3 The perspective view of the tooth corresponding to the first tooth of the indicated V phase is enlarged. based on Figure 1 ~ Figure 4 , the structure of the stator 100 will be described. in addition, image 3 The upper layer shows the winding sequence of the first phase (U phase), the middle layer shows the winding sequence of the second phase (V phase), and the lower layer shows the winding sequence of the third phase (W phase).

[0018] For example, the stator 100 is combined with a rotor using permanent magnets to form a brushless DC motor (synchronous m...

Embodiment approach 2

[0044] Figure 5 It is an explanatory drawing for demonstrating the motor 300 for blowers concerning Embodiment 2 of this invention. based on Figure 5 , the blower motor 300 will be described. This blower motor 300 includes the stator 100 according to the first embodiment.

[0045] Such as Figure 5 As shown, the blower motor 300 includes a rotor 38 , a bracket 39 , a molded stator 40 molded from the stator 100 , a connection member 41 (substrate), and the like. The blower motor 300 is manufactured by assembling the wiring member 41 connected to the outside to the stator 100 , performing molding after mechanical and electrical bonding, and then assembling parts such as the rotor 38 and the bracket 39 . Therefore, since the motor 300 for a blower is equipped with the stator 100 of Embodiment 1, it becomes a high-quality product.

Embodiment approach 3

[0047] Figure 6 It is explanatory drawing for demonstrating the air conditioner 400 which concerns on Embodiment 3 of this invention. based on Figure 6 The air conditioner 400 will be described. This air conditioner 400 is equipped with the blower motor 300 according to the second embodiment.

[0048] Such as Figure 6 As shown, the air conditioner 400 includes an indoor unit 42 and an outdoor unit 43 connected to the indoor unit 42 . A blower 44 is mounted on the outdoor unit 43 . A blower (not shown) is also mounted on the indoor unit 42 . Therefore, by mounting the blower motor 300 according to Embodiment 2 on the indoor unit 42 and the outdoor unit 43 , quality can be improved.

Abstract

The utility model provides a stator of a motor, a motor for an air blower, and an air conditioner. The stator of the motor, through maintaining tension, enables a winding hung on a terminal not to be loosened so as to ensure an insulation state between the winding and a stator iron core. A magnetic lead (2a), which becomes the end-portion side of the winding (2), of the stator (100) is further wound at a state when the magnetic lead is hung on the terminal (4).

Description

technical field [0001] The present invention relates to a stator of a motor having three terminals for supplying power to a three-phase winding, a motor for a blower using the stator, and an air conditioner equipped with the motor for a blower. Background technique [0002] Conventionally, there is a motor stator provided with three terminals for supplying power to three-phase single-phase Y-connected windings. As such a stator, a stator for a motor is proposed in which after winding a wire on the stator core, the terminal of the winding is hung on a part such as a terminal made of a punched copper plate, and heat caulking called fusion is used. The method is to electrically connect the power supply terminal and the neutral point terminal (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-96838 (Embodiment 1 etc.) [0004] In the method described in Patent Document 1, when manufacturing a motor in which two Y wires are...
