Problems solved by technology

[0005] In the structure described in Patent Document 1, after winding the stator core, when the end of the winding is hooked to the terminal, a load due to the tension of the winding is applied to the terminal, and the terminal may be deformed.
In addition, when the winding is hooked to the terminal to reduce the tension of the winding so as not to deform the terminal, the winding at the part wound on the stator core is loosened, and the core and the winding come into contact, and the insulation state of the winding and the core cannot be ensured. Possibility (refer to the part of Fig. 19 #2 of Patent Document 1)

Embodiment approach 1

[0019] figure 1 It is a perspective view showing a structural example of the stator (hereinafter simply referred to as the stator 100 ) of the electric motor according to Embodiment 1 of the present invention. figure 2 It is a perspective view showing the state where the stator 100 is reversely bent and wound. image 3 It is an explanatory diagram for explaining the winding sequence of the stator 100 . Figure 4 is magnified to represent the image 3 A perspective view of the tooth corresponding to the first tooth of the V phase shown. based on Figure 1 to Figure 4 , the structure of the stator 100 will be described. also, image 3 (a) shows the winding sequence of the first phase (U phase), (b) shows the winding sequence of the second phase (V phase), and (c) shows the winding sequence of the third phase (W phase).

[0020] The stator 100 is combined with a rotor using, for example, permanent magnets to constitute a brushless DC motor (synchronous motor). In addition...

Embodiment approach 2

[0040] Figure 5 It is an explanatory drawing for demonstrating the fan motor 300 which concerns on Embodiment 2 of this invention. based on Figure 5 , the fan motor 300 will be described. This blower motor 300 has the stator 100 according to the first embodiment.

[0041] Such as Figure 5 As shown, the blower motor 300 has a molded stator 40 obtained by molding a rotor 38 , a bracket 39 , and a stator 100 , connection parts 41 (substrate), and the like. The fan motor 300 is produced by assembling the external connection parts 41 to the stator 100, mechanically and electrically joining them, molding them, and then assembling components such as the rotor 38 and the bracket 39 . Therefore, the motor 300 for a fan has the stator 100 of Embodiment 1, and becomes a high-quality product.

Embodiment approach 3

[0043] Image 6 It is explanatory drawing for demonstrating the air conditioner 400 which concerns on Embodiment 3 of this invention. based on Image 6 , the air conditioner 400 will be described. This air conditioner 400 mounts the fan motor 300 according to the second embodiment.

[0044] Such as Image 6 As shown, the air conditioner 400 has an indoor unit 42 and an outdoor unit 43 connected to the indoor unit 42 . A fan 44 is mounted on the outdoor unit 43 . A fan (not shown) is also mounted on the indoor unit 42 . Therefore, by mounting the fan motor 300 according to Embodiment 2 on the indoor unit 42 and the outdoor unit 43 , quality can be improved.

Abstract

PROBLEM TO BE SOLVED: To provide a high quality stator of an electric motor capable of securing an insulation state between a winding and an iron core by manufacturing the stator by increasing tension so that a winding at a part wound around a stator icon core is not loosened while reducing the load by the tension applied to a terminal so that the terminal does not deform.SOLUTION: A stator 100 has an end of a winding 2 hooked to a terminal 4 while tension is lowered after the end of the winding 2 is wound around an insulation part 3 such that the end is not loosened.

Description

technical field [0001] The present invention relates to a motor stator having three terminals for supplying power to a three-phase single-phase Y-connected winding, a fan motor using the stator, and an air conditioner equipped with the fan motor. Background technique [0002] Conventionally, there is a stator of a motor having three terminals for supplying power to a three-phase single-phase Y-connected winding. As such a stator, a stator for a motor has been proposed. After winding the wire around the stator core, the terminal of the winding is hooked to a part such as a terminal made by bending a rectangular wire, and then welded by thermal riveting called melting. The power supply terminal and the neutral point terminal are electrically connected by the method (for example, patent document 1).
