VARIBLOC® / VARIMOT® variable speed gearmotors
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
- 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.

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.

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.
