Working Principle:
The inverter uses vector control to decompose motor current into flux-producing and torque-producing components through coordinate transformation. This enables independent regulation of magnetic flux and electromagnetic torque, optimizing motor efficiency across the entire operating range. The energy feedback function captures braking energy and returns it to the DC bus or grid, minimizing energy waste. The V/F adaptive function monitors load conditions and automatically adjusts the voltage-to-frequency ratio to reduce
