Brushless DC Motor

Brushless DC motors are realized with semiconductor switching devices electronic commutation, namely electronic switch instead of-contact commutator and brushes. It is characterized by high reliability, commutation spark-free, and low mechanical noise, widely used in high-end audio, video and electronic equipment and office automation equipment.

Brushless permanent magnet rotor stator, multipolar winding, position sensors and other components. Change of position sensor based on rotor position, along a certain order for the stator winding current flow (that is, detection of position of the stator winding of the rotor relative, and in determining the location of the position sensor signal, by the signal conversion circuit to control power switching circuit, according to a certain logic phase current switch). Stator output voltage from the sensor-controlled electronic switching circuit.
