Variable frequency drives (also called "VFDs," "AC vector drives," "inverters" or "variable speed drives") can be thought of as a motor controller that operates the motor by changing the applied voltage and frequency to the motor. A VFD can control the speed of a motor, as well as how it starts and stops. One advantage of using a VFD is it limits the inrush (starting) current, which is easier on the motor.
According to Electrical Construction and Maintenance Magazine, variable frequency drives are "the most effective motor controller in the industry today."
Screw conveyors are designed for moving and distributing bulk material. Some common types of screw conveyors include horizontal/inclined shafted screw conveyors (the most common type of screw conveyor used for bulk material handling), shaftless screw conveyors (typically used with sticky, high moisture and viscous loads), screw feeders and live bottom conveyors (used to move various types of loads at a constant and controlled speed and usually incorporate more than one gearbox) and vertical screw conveyors (used to move dry or semi-fluid loads at very steep inclines).
Frequency inverter reducers are a complete package solution with a gearbox, motor and Variable Frequency Drive (or VFD) that are specifically paired together in order to create the best solution. When the relationship between the motor, gearbox and VFD are all considered upfront, there is an opportunity to create an optimized, cost effective and efficient system.
