Power through Efficiency

Variable Displacement

Variable Displacement motors are the most efficient method of transmission of hydraulic to mechanical power. They are available in five cylinder BV format and seven cylinder TV format covering a wide range of displacements, all with electronic control.

The motors are able to vary displacement from any displacement from minimum to maximum. Due to the variation of displacement being by altering the crankshaft stroke the motor retains it’s high efficiency even in very low displacements, unlike some other variable motor designs.

BV1

Variable up to 250 cc/rev

Variable up to 3.9 Nm/bar

Variable up to 55 kW

SAI BV Motors have five cylinders where the displacements can be varied between a minimum and maximum displacement giving very high levels of performance.

The displacement is changed electronically by altering the stroke of the crankshaft which enables high efficiency to be maintained in all displacements.

BV2

Variable up to 500 cc/rev

Variable up to 7.8 Nm/bar

Variable up to 75 kW

TV1.5

Variable up to 400 cc/rev

Variable up to 6.5 Nm/bar

Variable up to 110 kW

SAI TV Motors have seven cylinders where the displacements can be varied between a minimum (can be down to zero) and maximum displacement giving optimum levels of performance.

The displacement is changed electronically by altering the stroke of the crankshaft which enables high efficiency to be maintained in all displacements.
