Control principle of brushless DC motor

To let motor turned up, first control Department on must according to Hall-sensor induction to of motor rotor currently where location, then in accordance with stator winding decided opened (or close) for flow device (inverter) in the power transistor of order, makes current order flows through motor coil produced forward (or reverse) rotating magnetic field, and and rotor of magnet mutual role, so on can makes motor Shun Shi/inverse Shi turned. When the rotor rotates to Hall-sensor when sensing the location of another set of signals, control and then open the next set of power transistor, and so the motor can continue to turn in the same direction until the control unit has decided to stop of the rotor power transistor is closed (or under the arm of power transistor); reverse motor rotor power transistor to open opposite order.
