Embodiment approach 1

[0032]

[0033] figure 1 It is a perspective view showing the structure of the stator assembly 110 according to Embodiment 1 of the present invention.

[0034] figure 2 is a plan view showing the structure of the stator assembly 110 . The stator assembly 110 includes a stator 1 , a substrate 5 attached to the stator 1 , and a lead wire group 7 connected to the substrate 5 .

[0035] The stator 1 includes an annular stator core 10 , an insulator (insulation portion) 3 arranged on the stator core 10 , and a coil 2 wound around the stator core 10 . Hereinafter, the direction of the axis C1 forming the center of the ring-shaped stator 1 is simply referred to as "axial direction". In addition, the circumferential direction around the axis C1 is simply referred to as "circumferential direction". The radial direction centered on the axis C1 is simply referred to as "radial direction".

[0036] The base plate 5 is disposed on one axial side of the stator core 10 ( figure 1 In...

Abstract

A motor (100), provided with: a stator (1); and a first substrate (51) and a second substrate (52) fixed to the stator (1). The stator (1) has: an annular stator core (10); and a first coil (2u) having a first phase and a second coil (2w) having a second phase, wound onto the stator core (10). The first substrate (51) has a first power supply wire (6u) for supplying power to the first coil (2u). The second substrate (52) has a second power supply wire (6w) for supplying power to the second coil (2w).

Description

technical field [0001] The present invention relates to an electric motor and an air conditioner using the electric motor. Background technique [0002] Usually, a ring-shaped substrate (wiring substrate) having power supply wiring is attached to the stator of the motor. The substrate is produced by punching out a substrate base material on which wiring and the like are formed. However, since the substrate is ring-shaped, the number of substrates punched out from a substrate base material of a certain area (the number of acquisitions) is limited. [0003] Therefore, Patent Document 1 proposes a structure in which a substrate is divided into two arcuate substrates, namely, a first arcuate substrate and a second arcuate substrate. A common pattern is formed on the first arcuate substrate, and three power line connection patterns respectively connected to the U-phase, V-phase, and W-phase coils are formed on the second arcuate substrate. [0004] prior art literature [000...
