Control mode of servo motor

Torque control: the torque control mode is to set the external output torque of the motor shaft through the input of external analog quantity or the assignment of direct address. For example, if 10V corresponds to 5nm, when the external analog quantity is set to 5V, the output of the motor shaft is 2.5nm: if the load of the motor shaft is lower than 2.5nm, the motor will rotate forward, and when the external load is equal to 2.5nm

FAQs about refrigeration compressors, do you know these?

Why control the impurity content and moisture content of the compressor and air conditioning system? Impurities entering the friction surface of the moving parts in the compressor pump body will cause abnormal scratches and wear. Impurities entering the solenoid valve, expansion valve, control valve, capillary tube and stop valve in the refrigerator system will block the valve hole or make the valve close tightly. And fail.
