For simple, variable speed applications up to 45 kW

Combining VARIBLOC®® and VARIMOT®® variable speed gear units with all types of reduction gear units within the SEW‑EURODRIVE modular concept creates variable speed drives with a low output speed and high output torque. Combining variable speed gearmotors with helical, parallel-shaft helical, helical-bevel and helical-worm gear units has proven effective at low speeds.

Variable-speed gear units are available with DRS.. and DRE.. motors. This means they meet the European requirements on efficiency levels and nearly all international efficiency levels.

Your advantages:

The foot- and flange-mounted versions can also be used to power machines without a reduction gear unit.

Speed can be adjusted mechanically, e.g. with a handwheel, or electromechanically using a servomotor.

VARIMOT® Variable Speed Gearmotor
 
VU/VZ series
In the power range up to 45 kW, the VU and VZ designs of the VARIBLOC®® wide V-belt variable speed gearmotors are used. Typical speed setting ranges are 1:4, 1:6 and 1:8. The U- or Z-shaped power flow and numerous combination possibilities with reduction gear units mean that these speed gearmotors can be supplied in a broad range of designs. They can easily be tailored to the most diverse machine structures.

D series
Friction disk variable speed gearmotors VARIMOT®® The D series is suited for power a power range up to 11 kW and speed setting ranges 1:4 or 1:5. The contact pressure between the driving pulley and the friction ring required for torque transmission is set automatically. The speed can even be adjusted when the gearmotor is at standstill.
