力矩电机 / 变频电机SUMMARY
Electric torque motor is a kind of special motor with soft mechanical properties and wide speed range. It has the advantages of low speed, high torque, strong overload capacity, fast response, good linearity characteristics, small torque fluctuation and so on. The output of the torque motor axle is not constant power, but constant torque. This kind of motor is suitable for winding, unwinding, stall, and speed regulating, are widely used in textiles, electric wire, metal-processing, paper, rubber, plastics and printing machine and industrial.
PRINCIPLE
When the load increases, the motor speed can be automatically decreased and the output torque increases to maintain the load balancing. The locked-rotor torque of this kind of motor is high and the locked-rotor current is small, so it can bear stalling. Due to the high rotor resistance, the heat generated is large, especially more serious when runs at low speed or even stall, so that the motor end cap fitted with a separate axial fan or centrifugal fan for forced air cooling (expect the one output torque is small). Torque motor with SCR control device, can be voltage and speed control, speed regulating range up to 1: 4, the rate of the speed change ≤10%.ELECTRIC MOTOR DATA
