YLJ series three-phase ac torque motors

Specifications

YLJ series torque three-phase induction motors have such special electrical performance as soft mechanical properties, excellent linearity, and wide range of velocity modulation. The velocity decreases and the motor torque grows as the load increases. Small changes in load can well result in correspondent changes in velocity. Tiny changes in the voltage of the power supply can lead to corresponding changes in velocity and motor torque. YLJ series are an ideal stepless voltage variable speed regulating motors.

The motor possesses such advantages as optimal structure, reliable operation, easy installation and maintenance, simple controlling circuit and easy handling. It can be used as the power source of the equipment for reeling in threads, opening rolls, velocity modulation, etc., in paper-making, textile, electric wires and cables, rubber, plastics and the processing of metal wire materials.

Operating conditions:

ambient temperature below 40°C,

altitude lower than 1000 metres above sea level, t

hree-phase AC power supply with voltage 380v(50HZ).

The motor adopts S9 non-cycle duty with continuous speed variation.

The protection class of YLJW is IP44, and that of YLJ is IP21.
