For simple, variable speed applications up to 45 kW (60 hp)

Combining VARIBLOC® and VARIMOT® variable speed gear units with reduction gear units of all designs in 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.

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 servo motor. Multi-speed motors can be applied for further enlargement of the setting range of variable speed gear units.

VU/VZ series
The VU and VZ designs of the VARIBLOC® wide V-belt variable speed gearmotors are used with power ranges of up to 45 kW. 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
Series D VARIMOT® friction disk variable speed gearmotors are intended for power ranges 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 control can be adjusted even when the gearmotor is at a standstill.
