45KW 55KW Electric Motor Inverter 3 Phase Variable Speed Drive For Heat Pump Water
Introduction of variable frequency drive
The ST310 series is the latest version of high-function vector inverters. V/F control mode; wave-by-wave current-limiting
control algorithm, which can instantly control the current and voltage; strong low-frequency load capacity; can realize
closed-loop control of asynchronous motors. The function is powerful, and the motion control function is obviously improved.
Inverter applications are very wide
1. Steel: rolling mills, roller tables, fans, pumps, cranes, ladle cars, converter tilting, etc.
2. Rolling steel wire: wire drawing machine, winding machine, blower, pump, hoisting machinery, fixed-length shearing,
automatic feeding.
3. Electricity: blower for boiler drum, feed water pump, centrifugal mixer, conveyor belt, pumping power station, flywheel, etc.
4. Petroleum: oil pumps, electric submersible pumps, water injection pumps, pumping units, etc.
5. Paper industry: paper machines, pumps, shredders, fans, mixers, blowers, etc.
