Motor

Disclosed is a motor, the motor according to an exemplary embodiment of the present disclosure including a stator arranged at an inner surface of a housing and including a magnet, a rotor core centrally arranged at the stator to pass through a rotation shaft, a rotor including an insulator covering the rotor core and a coil wound on the insulator, a commutator coupled to the rotation shaft to be electrically connected to the coil, and a brush coupled to the housing to be closely contacted to the commutator, wherein the insulator is formed with a short-circuit prevention unit formed on a drop path of conductive particles in order to prevent the short-circuit between the rotor core and the commutator from being generated by the conductive particles generated by the commutator and the brush.
