Brushless dc motor controller manufacturers about working principle and the maintenance of the controller

brushless dc motor controller manufacturers about working principle and maintenance of the controller, when the turn to turn the speed signal by wire to the controller to the main processing chip. Controller in the main processing chip respond according to the received signal, and the control signal and driving signal to the logic circuit and the power transistor, the output motor control and drive signal, the brushless motor running. The rotation motor, its internal position sensor ( The hall element) To detect the rotor magnetic pole position signal, feedback to the controller, the main processing chip control power transistor conduction and closed accordingly. When the press brake, the brake of the brake signal by the splice pieces to the controller, controller of brushless dc motor controller after the main processing chip to deal with the signal, the output of braking signal makes the power transistor in the closed state, make the brushless motor power, achieve the goal of the brake. In the process of electric bicycle to control, the main processing chip both the current control signal through the splice pieces, displayed in the indicating instrument. In order to know the working principle of the brushless motor controller circuit can be divided into several major function, such as power supply circuit, starting circuit, the brake circuit, control circuit, under-voltage protection circuit, over-current protection circuit. Between controller and brushless motor controller usually consists of three relatively coarse wire and no thread to link, brushless dc motor controller with coarser lead as controller connected to the motor of the three phase line, a fine of five lead for the controller and motor controller hall original connection wire, the multimeter test voltage of the wire. http://www。 tcmotor。 Com/foshan electrical and mechanical equipment co. , LTD. , brushless motor controller, brushless dc motor controller, dc servo motor controller, planetary reducer, brushless drive, electrical and mechanical, foshan electrical and mechanical equipment co. , LTD
