Variable Frequency Drives (VFD’s)

•If a VFD is used and speed is reduced too much the starting windings burn out. Constant Torque Loads • Require the same amount of torque at low speeds as high speeds. – For a given weight on the belt, the torque to turn the belt is always the same regardless of speed. • Horsepower increases or decreases as a direct function of speed.

Example: Driving a chain conveyor with a gear motor and VFD

Jun 12, 2012· There is a maximum of four boxes each weighing 500 kg on the conveyor. The chain itself has a weight of 300 kg. The friction factor between chain and base is specified at μ = 0.2. A mechanical stop is mounted at the end of the chain conveyor which aligns the boxes before they are pushed onto a second conveyor belt.

The fundamentals of matrix variable frequency drive technology

Jan 17, 2017· Variable frequency drives (VFDs), also known as variable speed drives (VSDs), and sometimes inverters, have benefited from many advancements since their introduction in the 1970s. During most of that time, however, the basic design of the drive remained the same, with improvements in performance, size, and cost coming mainly from advances in

3 Popular Control Methods for Positioning Conveyors

Jul 03, 2016· Most conveyor applications run at either a constant or variable speed, and therefore require only velocity control from the conveyor’s main drive motor. But positioning conveyors – like edge-belt conveyors for PC board assembly and positioning conveyors used in automated checkweighers – need to do more than just velocity control. The main drive motor needs to start and stop
