Embodiment approach 1
[0089] [About the structure of the motor]
[0090] Figure 1A It is a plan view showing the motor 1 according to the first embodiment. Figure 1B It is a side view showing the motor 1 of the first embodiment. Figure 1C yes Figure 1B Sectional view of line 1C-1C in. However, in any of the drawings, insulators such as casings and insulators are not shown. The motor 1 has a shaft 2, a rotor 3, a stator 4, an insulator (not shown), stator coils U11, U22, U32, U41, V12, V21, V31, V42, W11, W22, W32, W41 and bus bars 51-54.
[0091] The length direction of axis 2 (relative to Figure 1A The direction perpendicular to the paper surface) is called the Z-axis direction, and the direction perpendicular to the Z-axis direction (relative to Figure 1A The direction parallel to the paper surface) is referred to as the X-axis direction and the Y-axis direction. The X-axis direction and the Y-axis direction are perpendicular to each other.

Embodiment approach 2
[0122] image 3 It is a perspective view showing the stator coil 5 of the second embodiment. In the configuration of the motor according to the second embodiment, descriptions of the same and overlapping contents as those of the first embodiment are omitted.
[0123] Such as image 3 As shown, in this embodiment, in the stator coil 5 which is a helical coil, there are a plurality of recesses 5g and 5h. The virtual envelope surfaces of the outer peripheral portion of the portion 5q and the outer peripheral portion of the coil corner portion 5s are recessed. The position where each of the plurality of recesses is arranged is the long side of the stator coil 5 , that is, the side of the coil line portion 5 q in the stator coil 5 which is a helical coil.
[0124] It includes a form in which the outer peripheral portion of the coil line portion 5q of the one-turn annular body and the outer peripheral portion of the coil corner portion 5s are located at the bottom of the concave ...
Embodiment approach 3
[0138] Figure 4 It is a perspective view showing the stator coil 5 of the third embodiment. In the configuration of the motor according to the third embodiment, descriptions of the same and overlapping contents as those of the first embodiment are omitted.
[0139] Such as Figure 4 As shown, the present embodiment is a form in which the stator coil 5, which is a helical coil, has a plurality of recessed portions corresponding to the outer peripheral portion including the coil end portion 5r, the outer peripheral portion of the coil line portion 5q, and the outer peripheral portion of the coil line portion 5q. The imaginary envelope surface of the outer peripheral portion of the coil corner portion 5s is recessed. That is, the position where each of the plurality of recesses is arranged spans one turn of the outer peripheral surface of the stator coil 5 in the stator coil 5 which is a helical coil.
[0140] The outer circumference of the coil line portion 5q of the one-tur...
