The present invention pertains to a DC motor driven by a switching-less direct current, and more particularly, to a switching-less DC motor for enhancing the efficiency of the kinetic energy of the motor by combining electrical energy (active energy) of a stator and magnetic energy (passive energy) of a rotor. The stator of the motor is formed by distributed-winding a coil around a non-magnetic disk board to be radial to shaft so that magnetic fields are formed at both sides of the stator and are located at two rotor centers. The rotor of the motor is formed to have two disk board type permanent magnets having a size corresponding to a magnetic field surface of the stator at both sides so that the same polarities of the two magnets face each other towards both magnetic field surfaces of the stator. When a DC current flows through the stator (armature) of the motor, the rotor is activated and rotates according to the "Maxwell dynamic model (magnetic principle)", and in this case, a rotational direction is determined by "Fleming's left-hand rule", and the motor provides high efficiency and constant power. |
