The present invention relates to a high-efficiency permanent magnet motor driven by a direct current (DC) without alternation, with the motor generating a high-efficiency kinetic energy synthesized from active energy of a stator and passive energy of a rotator, comprising: a stator comprising a coil distributively wound radially around a circular planar PCB, creating a magnetic field on both sides of the stator located at the center of two rotators; and a rotor comprising two circular planar permanent magnets with a corresponding size to the magnetic field of the stator, with the magnet having both faces magnetized arranged such that the magnetized faces of the magnets and the magnetic fields on both sides of the stator facing each other have the same polarity. Constant power is provided when DC power is applied to the coil of the stator, the rotor rotates, in the absence of an AC.
