SIX-PHASE DC SQUARE-WAVE PERMANENT MAGNET BRUSHLESS MOTOR

摘要

A six-phase DC square-wave permanent magnet brushless motor is provided. The motor comprises a controller, a driving circuit of a bootstrap winding, an inductance value detection circuit group of no energized windings under excitation pulses and a brushless motor body. The controller is connected to the brushless motor body through the driving circuit of the bootstrap winding and the inductance value detection circuit group of the no energized windings under the excitation pulses respectively. The motor can achieve commutation effect of a brushless motor with position sensors, and can eliminate the torque ripple, and has advantages of simple structure and processing convenience.
