SAI S.p.a products

A series of variable displacement radial piston motors with an integrated electronic control system supplied together with the motor. The variable displacement means that the motor can be used at any level of displacement between the maximum and the minimum, maintaining a high level of efficiency even with very low displacement levels. These motors are therefore ideal for any circuit with a wide range of functions that require very high performance levels.

The sustainable capacity and high pressure make T motors ideal for heavy duty use. The TV-TD motors enable continuous displacement variation. It is possible to reach a minimum displacement of 0cc from any maximum displacement. Maximum efficiency enables excellent performance of the motors, even at 10% of the maximum displacement.

Dual displacement motor coupled with planetary gearbox with 6,231:1 reduction ratio.

7 piston double displacement motor, with integrated planetary gearbox of 6:1 reduction ratio, also avaible with negative brake (TS8DF).

Wheel drive units, with optional integrated static brake. Compact high torque motors that bear radial loads. The efficiency of the SAI motor, combined with a single stage gearbox, offers maximum starting torque and high-precision rotation control. The use of double displacement or continuous variable displacement offers an extension of the range of performance up to very high speeds. The variable displacement, if required, can reach 0 cc/rev.
