An embodiment provides a motor comprising: a shaft; a rotor coupled to the shaft; a stator arranged to correspond to the rotor; a housing accommodating the stator; a first bearing supporting the shaft; and a bearing housing supporting the first bearing, wherein the first bearing includes a first inner surface disposed toward the shaft and a first outer surface disposed opposite to the first inner surface, the first inner surface is slidably arranged with respect to the shaft, and the first outer surface is fixed to the bearing housing.

Motor

An embodiment provides a motor comprising: a housing having an opening; a stator disposed inside the housing; a rotor arranged to correspond to the stator; a shaft coupled to the rotor; and a cover arranged to cover the opening, wherein: the cover comprises a plate part, a protruding part formed to protrude from the plate in the axial direction, and a plurality of protrusions formed to protrude from the protruding part in the axial direction; and the thickness (T) of the protrusions in the radial direction is larger than the thickness (T) of the protruding part in the radial direction. Accordingly, through the structural shape of the cover, the motor can minimize foreign matter produced when the cover is press-fitted into the housing.

Cover and motor comprising same

An embodiment relates to a motor including 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. The cover includes 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.

One embodiment relates to a cover assembly and a motor including the same, the cover assembly comprising: a cover body; and a plurality of grooves formed on the upper surface of the cover body so as to guide coils, wherein a hole is formed at one side of the groove so as to penetrate the cover body. Therefore, the motor guides the coils to the outside by using the hole formed in the cover assembly such that assemblability is improved.
