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