As a leading manufacturer of drive technology, we also supply mechanical variable-speed gearmotors. For both series, VARIBLOC® and VARIMOT®, you can easily infinitely adjust the speed mechanically using a handwheel or remote control.
Speeds of up to 45 kW can be easily adjusted mechanically

Mechanical variable-speed gearmotors are simple yet robust drive components that represent an inexpensive alternative in many materials handling and process engineering applications. This is because you control the speed infinitely variably yourself: mechanically using a handwheel or via remote control. The process does not involve any costly control cabinets or frequency inverters at all.
There are two series to choose from: VARIBLOC®, the wide V-belt series, provides power ratings up to 45 kW and the speed setting ranges 1:4, 1:6 and 1:8. The VARIMOT® friction disk variant is suitable for power ratings of up to 2.2 kW and for the speed setting range 1:5.
