Abstract
An embodiment relates to a motor comprising: a shaft; a rotor which is coupled to the shaft; a stator which is disposed outside the rotor; a housing which accommodates the rotor and the stator and has an opening formed at one side thereof; and a cover which covers the opening, wherein the cover comprises a cover plate portion; and a side wall which extends axially from the cover plate portion, and at least three grooves are formed in the side wall. Accordingly, the motor according to the embodiment can guarantee the sealing performance while preventing the bearing from being damaged when the rotor is assembled on the inside of the stator.
Claims12
A motor comprising:
- a shaft;
- a rotor coupled to the shaft;
- a stator disposed outside the rotor;
- a busbar disposed above the stator;
- a housing in which the rotor and the stator are disposed and which comprises an opening;
- and
- a cover coupled to the housing,
- wherein the cover comprises a cover plate portion, in which a hole is formed, and a sidewall extending downward from the cover plate portion,
- wherein the sidewall comprises an outer surface and a plurality of grooves formed in the outer surface, and
- wherein the plurality of grooves of the sidewall are spaced from a top surface of the cover and a bottom surface of the cover and extend only partially along a length of the sidewall in an axial direction.
A motor comprising:
- a shaft;
- a rotor coupled to the shaft;
- a stator disposed outside the rotor;
- a busbar disposed above the stator;
- a housing in which the rotor and the stator are disposed and which comprises an opening;
- and
- a cover coupled to the housing,
- wherein the cover comprises a cover plate portion, in which a hole is formed, and a sidewall extending downward from the cover plate portion,
- wherein the sidewall comprises an outer surface and a plurality of grooves formed in the outer surface,
- wherein the cover plate portion comprises a plurality of grooves, and
