Frequency Inverter for Screw Extruding Machines

A Variable Frequency Drive (VFD) is a power control device that utilizes variable frequency and microelectronic technology to control the working power frequency of an AC motor, thus regulating its speed. It consists of various components, such as a rectifier (AC to DC), filter, inverter (DC to AC), braking and driving units, detection unit, and micro processing unit.

The frequency inverter is perfectly suitable for extruding machines, as it can easily achieve precise control and has a "zero servo" function that allows for high torque even when running at 0 Hz. Additionally, the automatic energy-saving function adjusts the output current according to the torque, resulting in energy conservation and enhanced system reliability and stability. This makes it the preferred option for extruding machines.
