VARIMOT® Variable Speed Gearmotor

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:

  • 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.
