It consists of foreign imported components such as microprocessor chip (CPU), thyristor, and integrated double-gate thyristor. The core technology is to dynamically track the change of motor load, adjust the voltage and current during motor operation (complete the action within 0.01 seconds), and ensure that the output torque of the motor matches the actual load demand without changing the motor speed. . It not only can ensure the normal operation of the motor, but also can effectively avoid the waste of electric energy caused by the excessive output of the motor, and has a good dynamic power saving effect. It can effectively reduce the power loss of the motor, improve the starting and stopping performance of the motor, and extend the service life of the motor. 10M Measuring Tape,Large Tape Measure,Longest Tape Measure,Black Tape Measure SHANGQIU CHAOYUE MEASURING TOOLS CO., LTD , https://www.chaoyuetools.com
