PURPOSE: A DC motor using solar cell is provided to disperse the initial drive load of the DC motor to utilize of a solar light cell plate of small size and generate power even where commercial power supply is supplied. CONSTITUTION: A DC motor using solar cell comprises a solar light cell plate(2), a PCB(3), a DC motor rotor(4), a magnet rotor(6) and a rotary body(7). The solar light cell plate(2) generates DC electricity using solar light. The PCB(3) drives the DC motor rotor(4) using the DC electricity generated by the plate(2) without using a brush. The rotor(4) is rotated under the control of the PCB. The magnet rotor(6) is coupled to a drive shaft(5) of the rotor(4). The rotary body(7) is inserted within the rotor(6) with a gap. The rotor(6) is a cylindrical permanent magnet.
