Introduction to the working principle of torque motor
The torque motor allows long-term low-speed operation, and its heating is very serious, usually using an external blower to force air cooling. When using a torque motor, pay attention to checking whether the blower is in good condition, and there should be a good ventilation environment around it, and no dry and flammable materials are allowed. Flammable dust or volatile combustible oils are near.
Due to different usage conditions, the types and specifications of materials that are wound or transferred by the torque motor driven machinery are different, and the required tension is different. It is required to adjust the torque of the torque motor, or to change the speed within a certain range, usually by adjusting the applied torque The voltage on the motor meets these requirements. A voltage regulator is usually used to change the input voltage of a torque motor. In the occasions where the mechanical characteristic hardness and adjustment accuracy are required to be improved, the SCR speed negative feedback control circuit can also be used for stepless speed regulation, but the system is more complicated.
