The high-voltage four-quadrant (hoist) inverter
The high-voltage four-quadrant (hoist) inverter adopts advanced vector control technology. At the same time, vector control without rotary encoder can be used according to the site conditions. The main difference between vector control and traditional V/F control is that vector control can The reactive current is distinguished from the active current (torque current). During the lifting process, the active current can be automatically adjusted according to the change of the load to make the output torque reach a better working condition, and the output torque can be 2.5 times of the rated torque.
