KV-series hyraulic motors have, over the KF series, the additional advantage of variable displacement, while offering the same features of reliability and performance.
This makes KV motors suitable for applications where the speed of rotation is to be varied in a proportion inverse to the torque requirements.
KV motor rated displacement can be reduced to one third.
This will result in increased speed while power will remain unaffected, which will sizeably reduce power pack costs, as the power can be made to suit the recuced capacity.
The high volumetric and mechanical efficiency will also bring about considerable saving in terms of costs of energy.
Displacement can be reduced by one of five different controls: manual direct, manual through a reduction gear, servo manual, hydraulic or automatic. KV motors are a must in those applications where steady power is required with variable torque and speed values.
