Abstract: An embodiment relates to a rotor comprising: a main body; an upper terminal disposed on an upper surface of the main body; and a lower terminal disposed on a lower surface of the main body, wherein the upper terminal comprises a first upper terminal and a second upper terminal; the lower terminal comprises a first lower terminal; the main body comprises a first hole and a second hole that penetrate the main body, wherein one end of the first lower terminal is connected to the first upper terminal through the first hole and the other end is connected to the second upper terminal through the second hole by means of a bus bar, and to a motor comprising the same. As such, it is possible to enhance space utilization inside the motor.

Abstract: 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.

Abstract: One embodiment relates to a gearbox and an actuator comprising same, the gearbox comprising: a housing having an opening; a cover arranged at the opening; a first gear part arranged so that one side thereof is supported by the housing, and the other side thereof is supported by the cover; and a second gear part and a third gear part arranged so that the first gear part is interposed therebetween. The first gear part comprises: a first shaft arranged so that one side thereof is supported by the housing, and the other side thereof is supported by the cover; a bearing arranged on the outer side of the first shaft; and a first gear arranged on the outer side of the bearing.
