Brushless DC motor can be divided into ontology, magnetic pole position sensor, and electronic reversing switch circuit (inverter) three parts. The armature winding is in the stator and the rotor was formed by the permanent magnet. Three-phase brushless motor bridge circuit at any moment are only under the bridge arm and each leg of a transistor, so that the two-phase in three-phase windings in series to the power, while the remaining one phase winding is not energized; The magnetic field generated by the stator and rotor permanent magnetic field is interactive, the rotor to produce torque drive turning. According to rotor position the Hall sensor measured, according to the order of 6 beats a pass transistor, resulting in changes in the order of the brushless motor stator rotating magnetic field.
