Technology of Asynchronous Motor Soft Starter and Simulation Research for Torque Control Strategy |
|
| Abstract: | Soft starter technology is advantageous to the improvement and the control of the startup proce-dure of asynchronous motor. The features of each kind of soft-start method were analyzed and compared in de-tail. Solid soft starter was realized on the bases of thyristor series technology and the torque control strategy. Through a 3 kW motor's simulation,the soft starter with torque control technology can greatly reduce the dy-namic torque and starting current. The performance is able to good control the startup procedure of asyn-chronous motor. |
| Keywords: | asynchronous motor soft starter torque control simulation |
