This series motors are characterized by high efficiency, energy saving, low noise, small vibration, light weight, reliable performance, easy installation and maintenance, etc., and have good insulation performance and moisture proof ability. It can be directly used in 6kV, 10kV power grid without intermediate transformer equipment.
This series of motors can provide a large starting torque at a small starting current, and can adjust the speed within a certain range. They are widely used in :
(1) requiring a larger starting torque than the starting squirrel-cage rotor motor;
(2) The capacity of the feed line is insufficient to start the squirrel-cage rotor motor;
(3) Relatively long starting time and frequent starting;
(4) A small range of speed regulation is required;
(5) Connect "electric shaft" for synchronous transmission and other occasions.
