A variator is a mechanical device that can continuously change the gear ratio between the drive and the driven unit, in order to deliver a smooth speed change of the driven shaft. The company offers variators and motorvariators with an aluminum and cast iron housing, manufactured by the Italian company MOTOVARIO.

The variators are characterised by quiet operation, lack of vibration and high efficiency. They can also provide two-way rotation. The maximum deviation from the set speed is 5% with  0.5 turns adjustment sensitivity.
