SEW VARIMOT® Friction Disc Variable Speed Geared Motors


SEW VARIMOT® Friction Disc Variable Speed Geared Motors


VARIMOT® type-series D variable-speed geared motors are suitable for mechanical engineering applications in the output range up to 11 kW when a simple but sturdy variable-speed drive is required.

VARIMOT® D variable-speed geared motors based on SEW AC motors are sturdy and easy to operate.

They provide mechanical, infinitely variable speed adjustment in the ratio range up to 5:1.
The motors are combined with reduction gear units to produce variable-speed drives with a high output torque and low output speed.

They can also be used without reduction gear units in either a foot or a flange-mounted version to drive a machine directly.

As with all SEW drives, VARIMOT® D variable-speed geared motors are available in a wide range of additional versions which guarantee perfect adaptation to every application.

As low-cost drives with individual combinations of torque and speed resulting from mounting of helical-, parallel shaft-, helical-bevel- or helical-worm gear units these motors mainly used in technically simple materials-handling and process applications such as those in the chemical industry, food and beverage, building materials industries in environmental technology.


• Sturdy with increased start-up torque
• High approved overhung loads on the reduction gear units
• Large number of finely tuned gear ratios in the reduction gear units, depending on size
• Choice of manual or remote speed adjustment
• Speed selection is possible even in standstill
