Torque motor winding equipment usually demand a fixed tension, fixed speed. But, when coiling, the diameter of the winding side will gradually become larger, affected by the amount of each round winding will also gradually increased, and demand greater torque. Therefore, in order to maintain constant tension and fixed speed, motor is necessary in diameter grows gradually slow down and increase torque (The diagram below)。 Look at the induction motor and the torque of the motor torque characteristic curve. From the chart, we found that the induction motor torque characteristic curve, strayed far, unable to meet the requirements. Torque motor torque characteristic curve, however, is very close to the coiling operation torque characteristics. In addition, the voltage changes, the torque will also change. By changing the voltage, can keep the torque motor droop, and change the torque of the motor (The diagram below)。 In addition, using the torque controller can change the voltage applied, the adjustment is very convenient! To sum up, torque motor mechanism suitable for use in a certain tension, a certain speed. Torque motor has the following characteristics: & bull; With a lot of starting torque and droop, can be in speed & ndash; Using torque characteristics of the velocity field. •Such as changes of motor voltage and torque is also changing. •Unlike induction motor and reversible motor, can get safe when low speed and locked-rotor torque.
