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.
- 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.
