Abstract
A motor having an improved assembly structure of a rotor core and a magnet is provided. The motor comprising a stator and a rotor that rotates with respect to the stator. The rotor comprises a rotor core that is disposed rotatably with respect to a rotary shaft and has a plurality of magnet coupling apertures disposed apart from each other at a particular interval in a circumferential direction of the rotary shaft. Additionally, a magnet is inserted into the magnet coupling aperture and a plate is coupled to opposite end portions of the rotor core. The plate includes a magnet support portion that is configured to support the magnet.
