Var-spe Hydraulic Variator – the technology invented and patented by Var-Spe solves the need for varying the speed of an electric motor through an innovative approach that is completely different from that of all other alternative solutions.┬áSpeed is varied physically exploiting the properties of the fluid and without electricity.

The Var-Spe technology is based on the principle of hydrostatic transmission: it consists of two units, i.e., a variable displacement pump and a fixed displacement hydraulic motor, both with radial pistons.The input shaft transmits the constant speed of the upstream motor to a series of pistons that compress and expand the oil inside the cylinders. By varying the oil flow rate and pressure, the speed of rotation transmitted to the output shaft is varied as well.
