Abstract: A camera module includes a fixed unit having an accommodating space; a moveable unit disposed in the accommodating space; an actuator configured to drive the movable unit in an optical axis direction; a substrate, disposed on a first side surface of the fixed unit, including a coil member of the actuator disposed on a first surface of the substrate; and connection pads, disposed on a second surface of the substrate, electrically connected to the coil member.

Abstract: Embodiments of the invention provide a motor rotor including a shaft, a rotor core having the shaft coupled thereto, and a balancing part formed integrally with the rotor core and the shaft, wherein the balancing part includes a balancing protrusion protruding therefrom.

Abstract: Embodiments of the invention provide a motor assembly including a terminal provided at a stator of a motor and electrically connected to a coil wound around the stator, and a controller formed with a coupling hole to which the terminal is coupled and electrically connected and controlling electric input and output to the terminal.

Abstract: Disclosed herein is a switched reluctance motor assembly, wherein a lower balancing part, which becomes a target to be cut for balancing, includes a lower balancing part body installed on a lower surface of a rotor part and an encoder protruding on a lower surface of the lower balancing part body. In the present invention, the encoder, which is a portion of a balancing part, becomes a target to be cut, thereby making it possible to more effectively perform balancing even with a smaller amount of cutting as compared with the prior art.

Abstract: Disclosed herein are a switched reluctance motor assembly and a method of assembling the same. The switched reluctance motor assembly includes: a shaft forming the center of rotation of a motor; a rotor part rotatably coupled on the shaft; a balancing part installed on upper and lower surfaces of the rotor part; and an impeller part installed on the balancing part, wherein the balancing part and the impeller part are formed integrally with or directly coupled to each other to prevent generation of unbalance at the time of attaching the impeller part, thereby making it possible to promote stable rotation.

Abstract: Disclosed herein is a bearing module for a motor that rotatably supports a rotational shaft and is sintered and molded, including: an upper bearing; and a lower bearing coupled to the upper bearing, wherein an oil receiving portion is formed in at least one of the upper bearing and the lower bearing.
