Abstract£º the main air extractor is one of the main equipment in sintering production. The change of wind pressure and air volume has a great influence on the sintering machine production. The 4600kW/6KV synchronous motor is used in the sintering main exhaust machine of a certain steel No. 1 and No. 2 sintering machine. By changing the throttle opening to meet the regulation of the sintering process£¬ because the motor speed can not be adjusted£¬ resulting in energy waste£¬ increasing the production cost£¬ the water resistance starting current is too large to start continuously. The new system adopts HARSVERT-A series high voltage frequency conversion to realize the start up and optimal control of synchronous motor.

Key words£º high voltage inverter£» application of synchronous motor 1 ϵͳµÄ×é³ÉºÍ¹¦ÄÜÌصã
