Embodiment approach

[0037] First, use Figure 1 ~ Figure 3 , the schematic configuration of the motor 1 according to the embodiment will be described. figure 1 It is a cross-sectional view of the motor 1 of the embodiment. figure 2 is the motor 1 along the figure 1 Sectional view of line II-II. image 3 is the motor 1 along the figure 1 Sectional view of line III-III. In addition, in figure 1 and figure 2 In , regions where the resin 130 exists are indicated by scatter-like hatching. In addition, in image 3 In , the structure inside the cover 160 such as the electric wire 170 is omitted.

[0038] Such as Figure 1 ~ Figure 3 As shown, the motor 1 includes a stator unit 100 , a rotor 200 disposed on the stator unit 100 , a shaft 300 provided on the rotor 200 , and a first bearing 410 and a second bearing 420 for rotatably holding the shaft 300 .

[0039] The stator unit 100 is a stator assembly in which the stator 120 is housed in the housing 110 . The stator unit 100 generates m...

Abstract

A motor comprising a housing (110) in which at least one penetrating female screw (111) is formed, a stator core (121) disposed within the housing (110), a resin (130) filled between at least the stator core (121) and the housing (110), and a sealing member (140) which seals the female screw (111) from the inside of the housing (110).

Description

technical field [0001] The present disclosure relates to an electric motor. Background technique [0002] Conventionally, in a motor in which a stator core is arranged in a case, a structure is known in which a liquid resin is poured into the inner space of the case and solidified to cover the stator core with resin. In such a motor, since resin is embedded between the stator core and the case, heat generated in the motor can be efficiently dissipated. Accordingly, it is possible to reduce the size of the motor. [0003] In the case of a motor with a stator core disposed in the case, in order to conduct electricity to the winding coil wound around the stator core, an opening for power supply is formed in the case, and an electrical connection such as a lead wire or a connector is provided in the opening. The structure of the component. Accordingly, electric power can be supplied to the electric motor via the electrical connection member to conduct current flow to the wind...
