Double Displacement

Image Series/Description Pdf
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.
