PURPOSE: A motor is provided to reduce the damage and the driving badness by constructing a housing of the motor with a transparent material. CONSTITUTION: Both ends of a cylindrical housing(110b) are tightly closed. A permanent magnet(108) is adhered within the housing(110b) and forms a magnetic field. A rotational shaft passes through one side of the housing(110b), is connected to the other side and installed on a coaxial place with the housing(110b). A rotor(106) is installed on the rotational shaft, opposite to the permanent magnet(108) and generates a rotational force by a supplied current and the magnetic field. A commutator(104) is installed on the rotational shaft in a predetermined direction and connected to the rotor(106). A brush(112) is installed within the housing(110b) so as to come in touch with the commutator(104) to supply power thereto.
