Product Description
Product Brief
Adopting DSP as core of control system, with high performance of magnetic flux inverter control.
Compare with V/F control, vecter control has greater supperiority, which inlay and integrate Non-PG Vecter Control(Sensorless Vecter Control) and V/F Control together. Widely applied to high speed control accuracy, rapid torque response and high performance at low frequency and other application sites of high requirement.
