hub motor  controller electronic reversing device, instead of the traditional mechanical commutation device (commutator and brush), not only retained the DC motor speed control with good starting characteristics, and AC motor with simple structure and easy maintenance This motor in good, reliable, therefore, the rapid development in recent years. Traditional DC motor armature is rotated, the pole is stationary, but bldc motor driver in this contrast, the magnetic pole is rotated, the armature is stationary, the armature winding current commutation can make use of position sensors and electronic switching circuit to complete. Brushless motor. hub motor driver generally motors, position sensors, and electronic switch consists of three parts. Motor itself consists of multi-phase (three phase, four-phase, five-phase range) armature windings on the stator pole and a certain number of permanent magnet rotor component. AA, BB, CC, said three-phase motor stator windings, NS is a permanent magnet, the motor rotor, PS is the rotor position sensor, and its coaxial rotor and motor rotor is connected, BG1, BG2, BG3 electronic switching circuits power switch, three-phase windings A, B, C respectively, BG1, BG2, BG3 in series to the power supply after. Its operation principle is that a signal controlled by the PS BG1, BG2, BG3 and other switch on on and off, when the switch turns on, the corresponding stator windings, there is current and magnetic field through the magnetic field and permanent magnetic interaction between the rotor pole will generate torque, the motor rotor, the motor coaxial with the rotor position sensor is connected, it also followed the rotation of the rotor and in turn to BG1, BG2, BG3 signal to control the turn on and off, to the armature winding current with the rotor position changes according to the order of commutation, the magnetic armature rotary stepper motor’s rotor to rotate continuously go on.
