Brushless direct current motor with magnet magnetic force utilized

The invention relates to the application of magnets in power equipment, in particular to a brushless direct current motor with magnet magnetic force utilized. The brushless direct current motor aims to solve the technical problem of how to replace force-electromagnetic force for cutting a magnetic line of force in a motor with the magnet magnetic force. The magnet magnetic force, attractive force and repulsive force are applied between a stator and a rotor of the motor. The rotor is provided with two circular-arc-shaped magnets in one plane, the two magnets are uniformly distributed, space angles between the two magnets are also uniformly distributed, and the two magnets provide N poles or S poles for the stator. The stator is provided with four electromagnetic coils in one plane, and the four electromagnetic coils are uniformly distributed and located in a rotor magnet magnetic field. If providing a magnetic pole axis N-S pole and located at the N pole of the rotor magnet magnetic field, the electromagnetic coils generate the magnet magnetic force to enable the rotor to rotate; if providing a magnetic pole axis S-N pole and located between the two magnets, the electromagnetic coils generate the attractive force and the repulsive force with the same direction as the magnet magnetic force to enable the rotor to rotate. The brushless direct current motor is higher in efficiency and smaller in size compared with a permanent magnet brushless direct current motor.
