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.
DRS.. and DRE.. motors. This means they meet the European requirements
on efficiency levels and nearly all international efficiency levels.
Your advantages:
- Increased starting torque
- Large permitted overhung loads of the reduction gear units
- Large number of finely stepped gear ratios of the reduction
gear unit, depending on size - Choice of manual or remote speed control
- Easy 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 servomotor.

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. |

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. |
