Embodiment Construction

[0043] Embodiments are described below with reference to the drawings.

[0044] In the embodiments, descriptions of configurations or elements other than the main part of the present invention are simplified or omitted for easy understanding of the descriptions. In addition, in the drawings, the size, shape, number, etc. of each element are just examples, and are not intended to be limited thereto.

[0045] In addition, in the following description, an axial direction is defined as the direction in which the rotor (axis) of the motor extends, that is, the direction in which the central axis of the rotor extends. In addition, the radial direction is defined as a direction perpendicular to the central axis of the rotor, and the circumferential direction is defined as a direction surrounding the central axis of the rotor. The circumferential direction is centered on the rotor, and one revolution is 360°.

[0046] In addition, the axial front side is defined as the side where th...

Abstract

The present invention provides a motor and a stator. The motor includes: a rotor capable of rotating around a central axis; an annular iron core disposed along a circumferential direction surrounding the central axis; a wire wound on the annular iron core; an insulator, It insulates between the ring iron core and the wire; and the first casing surrounds the rotor, the ring iron core, the wire and the insulation. At least one end of the rotor protrudes from the housing in an axial direction in which the central axis extends. The toroidal core has a plurality of core segments. Each of the plurality of core segments includes: a core back; and a tooth portion protruding from the core back in a radial direction perpendicular to the central axis, and a lead wire is wound around the tooth portion. The insulator includes: an insulating part arranged between the ring core and the lead wire; a terminal part connected to the insulating part; and a movable part capable of changing the terminal part from the first orientation to the second orientation. The terminal portion holds a terminal. The wire is wound around the terminal.

Description

technical field [0001] The invention relates to motors and stators. Background technique [0002] Motors such as a brushless DC (BLDC) motor can be reduced in size and cost by, for example, narrowing the spaces between the plurality of slots, that is, the slots. Here, the tooth space refers to the space between the two tooth portions around which the lead wire is wound. [0003] However, when the slots become narrower, it becomes a problem to increase the speed and improve the quality of the winding process of winding the lead wire around the teeth. This is because, in such a case, as the speed of the operation of the winding nozzle of the winding machine is increased, the vibration of the operation of the winding nozzle increases, and the winding nozzle may come into contact with the stator core. [0004] A straight iron core is effective for solving this problem. The straight core has a core back and a tooth portion extending in a vertical direction relative to the line...
