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.

[AC torque motor]YDLJ series torque three-phase asynchronous motor

The YDLJ series torque three-phase asynchronous motor is a special motor with soft mechanical characteristics and a wide range of speed regulation. When the load increases, the speed of the motor can automatically decrease, while the output torque increases to maintain balance with the load. The locked rotor torque of the torque motor is high, the locked rotor current is small, and it can withstand a certain period of locked rotor operation. Due to the high voltage and loss of the rotor, the heat generated is also significant, especially during low-speed operation and locked rotor. Therefore, the motor is equipped with an independent axial or centrifugal fan on the rear cover (except for those with output torque of 100 machine base sizes and below) for forced ventilation cooling. The torque motor is equipped with a thyristor control device, which can adjust voltage and speed, with a speed range of up to 1:4 and a speed change rate of �� 10%. The characteristics of this series of motors make them suitable for winding, unwinding, stalling, speed regulation and other applications, and are widely used in industrial fields such as textiles, wires and cables, metal processing, papermaking, rubber, plastics, and printing machinery.

Application scope:
1�� Winding: Winding is a very important process in the processing of wires and cables, textiles, metal processing, papermaking, and other industries. The diameter of the roll gradually increases during product winding, and it is very important to maintain the tension of the rolled product unchanged throughout the process, because excessive tension can thin or even break the wire diameter, or cause uneven thickness of the product, while insufficient tension can cause loose winding. In order to maintain constant tension during the winding process, it is necessary to increase the output torque of the motor that drives the drum when the diameter of the product wound onto the reel increases. At the same time, to maintain the same linear speed of the wound product, the speed of the reel must be reduced accordingly. The mechanical characteristics of the torque motor can precisely meet this requirement.
Figure 1 shows a schematic diagram of the winding process and the matching curve between the torque speed characteristics of a typical torque motor and the winding tension. In the shaded area where two curves intersect within the speed range of 1/3 to 2/3N0 of the torque motor (roll to diameter ratio 1:2), the winding characteristics are most ideal. At this point, P=F · V=constant, that is, T · n=constant (P: power, F: tension, V linear velocity, T: torque, n: motor speed). For roll to diameter ratios of 1:3, 1:4, or greater, the requirement for controlling tension can be achieved to some extent, but with slightly lower accuracy. For situations where the roll to diameter ratio is large and tension control accuracy is high, dual speed or three speed torque motors can be used to achieve this.
Usually, there are many varieties and specifications produced by each device. When the materials and specifications change, the required tension and speed are also different. In this case, a voltage regulator can be used to adjust the motor terminal voltage, which can achieve the purpose of increasing or decreasing the motor output torque.

Figure 2 shows the characteristic curve family of motors with different voltage torque, where the relationship between output torque and voltage is T �� U2.
The torque motor has advantages when wound:
1. The tension remains stable during the process from an empty disc to a full disc.
2. The tension adjustment is convenient and can be repeated correctly after one adjustment.
3. Reliable structure, easy maintenance, control, easy operation, and low cost.

2�� Open book (braking constant power characteristic)
Uncoiling, also known as unwinding, unwinding, or rewinding, is shown in Figure 3. In industrial production, it is sometimes necessary to transport products wound on a drum to the next process. During the conveying process, it is required to apply a tension opposite to the transmission direction to the product, while maintaining a constant linear velocity and back tension of the product transmission as the cylinder diameter changes. This requires the motor to have a constant braking power characteristic. By utilizing the mechanical characteristics of torque motors during braking,
As shown in Figure 4, loosening the rolled products before processing can prevent the quality of the products from being affected by looseness and tightness during the unwinding process. The principle is analyzed in the same way as during winding.
3�� Stepless speed regulation
The mechanical characteristics of torque motors are very soft. When the load increases, the motor speed decreases and the output torque increases, which is proportional to the square of the voltage. If the load is fixed, the speed of the motor will vary with the voltage, as shown in Figure 5. Therefore, on a device with a constant load, any speed can be obtained by changing the input voltage of the motor through a voltage regulating device. However, when the torque motor operates at low speeds, its efficiency is extremely low, which is not conducive to long-term low-speed operation.

4�� Blocked rotation
In some special occasions, it is sometimes required for the motor to maintain a static torque for a period of time, such as maintaining tension during the initial stage of cable winding; Forging clamping devices for large forging presses, etc. Due to the high impedance of torque motors; Its stalling current is relatively small, and forced ventilation is used, so it can meet the stalling requirements for a certain period of time. The allowable stalling time should be based on the calibration value on the nameplate. If a longer stalling time is required, a larger torque motor can be selected by reducing the terminal voltage of the torque motor.
5�� Other
Torque motors can also be flexibly applied according to their various characteristics, such as having the characteristics of DC series excited motors, which can partially replace DC motors; For example, due to the high resistance characteristics of its rotor and the large starting (stalling) torque, it can be applied in opening and closing gates (valves) and drag systems with high resistance torque; It can also be used in devices with frequent forward and reverse rotation or other similar mechanical actions due to its high starting (stall) torque, low starting (stall) current, and high mechanical strength of solid rotors.
