the advantage of the brushless motor, different from a brushless dc motor, brushless dc motor without the use of mechanical brush device, using square wave self-control type permanent magnet synchronous motor, with hall sensor to replace carbon brush and commutator rotor in ndfeb permanent magnet materials, the performance has great advantages, compared with the general traditional dc motor speed regulating motor is the most ideal. Brushless dc motor stator winding of more balanced three-phase y connection, with three phase asynchronous motor is very similar. On the rotor of the motor with the magnetization of the permanent magnet has, in order to detect the polarity of the motor rotor, inside the motor is equipped with position sensor. Drive consists of power electronic devices and integrated circuit, its function is: accept the motor start, stop, brake signal, to control the motor start, stop, and the brake; Accept the position sensor signals and positive &negative, used to control the inverter bridge on and off of each power tube produce continuous torque; Accept the speed instruction and speed feedback signal, which is used to control and adjust the speed; To provide protection and display, and so on. Brushless dc motor is widely used in household appliances, auto parts, power tools, office automation, industrial equipment, medical equipment, personal care, robots, and many other industries.
