In the metal processing, textile, paper, rubber, chemical and electric wire and cable industry products, often needs to be wound on the reel ( disc ) on, there is a need to address the problem, how the diameter of drum from the beginning to the final stage of gradually increased throughout the process, Zhang Li and speed changes to keep the allowable range, in order to solve the above problems, mostly in the mechanical structure to add all sorts of auxiliary equipment or by other transmission system in order to achieve, but its effect is often not very ideal, there is also a complicated equipment, high cost, the use of maintenance problems and other issues, along with the our country industry and agriculture development, high speed, excellent quality and improve the degree of automation, the issue is more outstanding.

YLJ, JLJ series torque motor has its unique electrical properties, when the load increases, the motor shaft speed can be automatically decreases, so that product winding Zhang Li remained basically unchanged, the superior is the match, so this series motors can also be called winding characteristic of torque motor. Because the motor has larger impedance, locked-rotor current also more general motor is small, and the structure uses a variety of needs, using the forced ventilation form, it can run in low speed range even in the locked state, and has the advantages of simple structure, no brush, slip ring, commutator and, with the same general asynchronous motor maintenance the advantage of easy.

Torque motor control

Torque motor is controlled according to different requirements, adjust the supply voltage, suitable for different needs of general Zhang Li, to a specification of the products, adjust good after Zhang Li, in later period does not need to be adjusted, the control method is very simple, any kind of pressure regulating device can be applied. Usually smaller motor output mostly adopts three-phase power, should be the maximum motor current ( can be rated output and a locked-rotor current when selecting the control schematic ), shown to the left.
