JS-LJ factory price three phase torque motor controller with speed adjustment

Brief Introduction

JS-LJ is a more economical choice with a lower price for limited budgets. The torque motor controller is a new type of electronic voltage regulation (open, closed loop) control device. It basically remains unchanged, and the motor performance and winding performance are coordinated and matched. It is an ideal matching device for mechatronic torque motors. The controller (board) adopts a thyristor to realize a stepless speed regulation of the motor, so that the voltage regulation is stable, the starting performance is good, and it has the advantages of small size, lightweight, high efficiency, convenient installation and use, and long service life.

Applications

Widely used in mechanical and electrical industries such as hardware, machinery, plastics, wires and cables, rope nets, printing and papermaking, textile printing and dyeing, chemical fiber, rubber, film rubber, and so on.

Main Features

• Wide range of use
• Small size and light weight
• Not prone to overheating
• Energy and cost savings
• Endurable with long life
• Has phase failure/break indication
• The three-phase motor regulates equilibrium
