Cleaner power supply

The vector control of the sine wave PWM converter is conducted to reduce harmonics and achieve a power factor of 1.0.

Common converter

Several inverter converters are made common to reduce converter capacity.

Various control methods

High-precision, high-response types are based on vector control with a speed sensor. The universal types are based on sensor-less vector control.

High-speed response roll speed

High-speed response increases the accuracy of strip thickness and tension control.
