PURPOSE: An energy-saving type high power DC motor is provided to increase an output by flowing current in an electromagnet when the magnetic force of a thick permanent magnet is maximum. CONSTITUTION: A central shaft(4) is installed in a case(2). A commutator(6) is installed in the central shaft to ground with a brush(12). An electromagnet(7) is installed in a rotary plate(5) which is combined with the central shaft. A permanent magnet(8) is firmly fixed by a permanent magnet support stand(9). The permanent magnets are located on the upper side and the lower side of the electromagnet.
