JLJ series torque three-phase asynchronous motor

In industries such as metal processing, textiles, papermaking, rubber, chemical engineering, and wire and cable manufacturing, it is often necessary to wind products onto reels (discs). There is a problem that needs to be solved, which is how to maintain the tension and speed changes within the allowable range during the entire process of gradually increasing the diameter of the reel from the beginning to the end. In order to solve the above problems, various auxiliary equipment is often added to the mechanical structure or other transmission systems are used to achieve them. However, the effect is often not ideal, and there are also problems such as complex equipment, high cost, and difficult maintenance. With the rapid development of industry and agriculture in China, the improvement of high speed, excellent quality, and automation level has made the above problems more prominent.

The YLJ and JLJ series torque motors have their unique electrical characteristics. When the load increases, the output speed of the motor can automatically decrease, keeping the tension during product winding basically unchanged. This advantage is coordinated and matched, so this series of motors can also be called winding characteristic torque motors. Due to the high impedance and smaller stalling current of electric motors compared to general motors, as well as the need for various structural purposes, forced ventilation is adopted. Therefore, it can operate for a long time in the low-speed range or even in a stalling state. Moreover, the structure is simple, without brushes, slip rings, rectifiers, etc., and has the advantage of easy maintenance and use compared to general asynchronous motors.

Control of torque motor
The control of torque motors is to adjust their power supply voltage according to different requirements to meet the needs of different tensions. Generally, for a product of a certain specification, after adjusting the tension, there is no need to adjust it again in the future cycle. The control method is simple, and any voltage regulating device can be applied. Usually, motors with smaller output mostly use three-phase power, and should be selected according to the maximum current of the motor (i.e. the current at rated output and when stuck). The control circuit diagram is shown in the left figure.
