摘要: A brushless DC motor includes opposed pairs of axial magnetic field type permanent-magnets. Two stators are axially arranged at two opposite sides a rotor, each and stator plurality equiangularly spaced electromagnetic zones in least one winding zone. control system is provided to detect phase angle the revolving speed rotor through sensor connection current its direction, enabling windings form with motor. By means detecting change sensor, controls permanent-magnet operate under different operation combinations output torques.
