Torque motorIncluding: DC torque motor, AC torque motor, and brushless DC torque motor. It is widely used in machinery manufacturing, textile, paper making, rubber, plastics, metal wire and wire and cable industries. Here, on the use principle and market application of torque motor, Senli Motor Xiaobian shares as follows:

Torque motor is a special motor with a large number of poles, which can be used at low speed or even blocked rotation(That is, the rotor cannot turn)It can still run continuously and will not cause damage to the motor. In this mode, the motor can provide a stable torque to the load(Hence the name torque motor). Torque motors can also provide torque in the opposite direction of operation(Braking torque). The shaft of the torque motor does not output power with constant power but with constant torque.

Constant torque characteristics Torque motor, in the general wide speed range, so that the torque is basically constant, suitable for two speed changes, require constant torque transmission occasions. For example, in printing and dyeing machinery, when the fabric is transmitted with a number of rollers, because the fabric is not wound on the roller, but is only attached to the surface of the roller to drive it, the diameter of the roller is not changed, and the constant torque characteristics of the motor should be used on this occasion to ensure that the torque is constant and the tension of the fabric is constant at different speeds.

Torque motors allow long-term low speed operation(It won't even stop)Its heat is very serious, and an external blower is usually used to force air cooling. When using the torque motor, we should pay attention to check whether the operation of the blower is good, and there should be a good ventilation environment around it, and dry flammable materials, flammable dust or volatile combustible oils are not allowed to be near.

Due to the different use conditions, the types and specifications of materials wound or transmitted by the machinery driven by the torque motor are different, the tension required is different, and the torque of the torque motor is required to be adjusted, or the speed change is required within a certain range, and the voltage applied to the torque motor is usually adjusted to achieve these requirements. To change the input voltage of the torque motor, a voltage regulator is usually used. When the mechanical hardness and adjustment accuracy are required to be improved, the thyristor speed negative feedback control circuit can also be used for stepless speed regulation, but the system is complex.

YLJ,YDLJSeries torque three-phase asynchronous motor is a kind of special motor with soft mechanical characteristics and wide speed range. When the load increases, the speed of the motor can automatically decrease, and the output torque increases to maintain the balance with the load. Torque motor has high locked-rotor moment and small locked-rotor current, and can withstand a certain period of locked-rotor operation. Because the rotor resistance is high, the high loss is large, and the heat generated is also large, especially when running at low speed and blocking, so the motor is equipped with an independent axial flow or centrifugal fan on the rear end cover (the output torque is small)100Except for the frame number and below), for forced ventilation cooling, torque motor equipped with thyristor control device, can be adjustable voltage speed, speed range up to1:4, speed change rate≤10%. The characteristics of this series of motors make it suitable for other applications such as winding, unwinding, blocking and speed regulation, and are widely used in textile, wire and cable, metal processing, red making, rubber, plastics and printing machinery and other industrial fields.
