SEW Eurodrive VARIGEAR® VU/VZ Series Variable Speed Gear Motor

For simple, variable speed applications up to 45 kW (60 hp)
Combining VARIGEAR® 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. The combination of variable speed drives with helical, parallel shaft helical, helical-bevel and helical-worm gear units has proven effective at low speeds.

Advantages:
Increased starting torque
Large permitted overhung loads of the reduction gear units
Large number of finely spaced gear ratios of the reduction gear unit, depending on size

Choice of manual or remote speed control

Intuitive operation
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 VARIGEAR wide V-belt variable speed gearmotors are used with power ranges of up to 45 kW (60 hp). 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.
