Working Principle:
The inverter employs a rectifier-DC bus-inverter topology with IGBT switching. The FOC algorithm decomposes stator current into flux-producing (d-axis) and torque-producing (q-axis) components through coordinate transformation, enabling independent control of magnetic flux and electromagnetic torque. The PID controller processes feedback signals from process sensors and adjusts the motor speed setpoint to maintain the desired process variable. The modular control architecture separates the power stage from the control logic, allowing independent maintenance and upgrades.
Installation Requirements:
- Install in a dry, ventilated environment free of corrosive gases
