ESV motoinverters


STM SpA, one of the leading power transmission manufacturers, has worldwide introduced its newly born ESV ( electronic speed variator ) during the Hannover Exhibition. Through an easy-to-use potentiometer it is possible to modify the output speed within the range of rpm 150 and 1500 but still keeping the same constant output torque.
Just plug the ESV in and, without any need to set up programmes, we will benefit of a speed variator without risk of oil leaking !
