Permanent magnet BLDC (Brushless Direct Current Motor) of ring winding

The invention relates to the technical field of a motor, and provides a permanent magnet BLDC (Brushless Direct Current Motor) of a ring winding. The BLDC comprises a DC power, a switching circuit, a rotor and a stator, wherein the stator is uniformly provided with a plurality of stator slots in which the stator windings are placed, a closed loop circuit is serially formed by the ends and tails of the stator windings according to the sequence of the stator slots, and the DC is used for powering a stator winding through the switching winding; the rotor is uniformly provided with permanents used for providing an excitation field. According to the BLDC provided by the invention, the torque ripple can be effectively reduced, and the BLDC is applicable to power drive with high performance.
