AC Variable Frequency Inverter Drives VFD for Screw Feeder 400V

Screw feeders are used in various industries for the metering of material into a production process. Screw feeder design closely resembles that of a screw conveyor, but unlike a screw conveyor, a screw feeder is required to be very precise and accurate. The screw in a screw feeder is completely filled with material, compared to a screw conveyor which is typically 40-50% filled. That is part of the reason the material is accurately discharged when the feeder screw is rotating at a controlled rate.

Application Challenges

· Fast Response
Capable of accurately regulating material feed.

· Load Detection
Capable of detecting an overload or no material in the screw situation.

· Speed Range
Be able to provide the required amount of torque throughout the speed range.

· Trip-less Operation
The product must be capable of continuing to operate after a momentary power loss or a fault.

Features of G7 matching feeder application



Open Loop and Closed Loop Flux Vector Motor Control

Excellent speed stability and low speed torque production is possible due to Flux Vector Control technology.

Overtorque and Undertorque Detection

Both the Overtorque and the Undertorque Detection functions can sense if there is an overloaded feeder or lack of material.


Accurate and quick response control of material into the production process

Auto-Restart after momentary power loss.

Feeders can quickly restart after fault or momentary power loss.

Power loss Ride-Through

The material feed is not interrupted during brief power loss.

Torque Limit

Use of Torque Limit can prevent screw or gear damage due to excessive torque from foreign material in the load.

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
