The Varibloc® V series variable speed drive can be combined with helical, parallel helical, helical-bevel and helical-worm reduction gear units to offer a maximum power rating of 45kW with a 1:8 maximum setting range. 

These drives can be supplied in U or Z shaped power flow styles and can be supplied in a broad range of designs to suit most machine structures.

Foot or flange mounted versions are also available to power machines without a reduction gear unit.

The speed can be adjusted manually or by remote speed control.
