Variable pulley systems

Economic speed control has a crucial part to play wherever drive systems are found in machines and installations.
VARMEC variable pulleys - which can be combinated with motor, measuring transducer and computer right up to a complete drive unit - meet the demands of design engineers and users for economical and reliable speed control technology in practically all cases.

Epicycloidal speed variators

The mechanical variator is based on an epicyclic transmission for variable ratios.
The motor rotates the solar rings which rotate the satellites. In turn these are in contact with the fixed outer ring and external mobile ring.
