Discussion On The Control Elements Of AC/DC Motor For Circuit Breaker

Speaking of the AC/DC Motor for Circuit Breaker, Xiaobian would have to say that the DC motor control technology, DC motor control technology has been well developed, the main digital control, no position sensor BLDC control, which two They have their own characteristics.

1, digital control

Digital control system is based on the microprocessor as the core, can achieve the previous continuous control can not imagine the high complexity, high precision control. With the development of microelectronics technology, the emergence of microprocessors and the speed of computing and the development of computer software, the automatic control system is over to the digital control system with digital processing and high speed digital processing as the core. As the digital speed control system is small, easy to achieve, etc., not only the general PID control, complex vector control, nonlinear robust control, fuzzy control and other methods can be achieved.

2, no position sensor BLDC control

As the AC/DC Motor for Circuit Breaker body to cancel the location, so that all the hardware are placed inside the electronic switch line, and to reduce the AC/DC Motor for Circuit Breaker size and cost. Since the conduction and commutation time of each phase winding can no longer rely on the position sensor signal, the magnetic pole position detection circuit is added to the control circuit. Since the motor is stopped or the rotational speed is low, the accurate rotor position signal is generally difficult Detection, so, no position sensor BLDC generally also need a special starting circuit, the other links and with the position sensor BLDC the same.
