Electronic gear

The electronic gear available through Bonfiglioli's latest VVVF drive in the Active series is a process by which Bonfiglioli uses a simple electrical signal termed a 'repetition frequency' to synchronise a slave drive or drives to a master drive so they run at a common output speed independently of each other.

The drives are electrically interlocked using low voltage control signals, so when the master is sped up or slowed down, the slaves follow with a very high degree of accuracy.

A further benefit is that Bonfiglioli can also program a proportional differential to have the drives running at different speed percentages to the master. They still follow the speed of the master up and down, but with a precise proportional difference matched through the entire speed range.

The electronic gearing solution is simple to set up and adjust, highly accurate, and included standard in all the Active range of inverters.

In applications now going into service the VVVF technology is being coupled with established gearbox and gear motor lines, such as W series worm drives. However, it can also be applied to F and C series helicals, A series helical bevel and Trasmital 300 series planetary reducers to provide an integrated solution to the user's mechanical and electronic requirements.
