The TD motor from SAI, is offered in sizes of 1.5, 2.5, 3.5. It can be distinguished with seven radial pistons. This piston attains continuous torque resulting to a better transmission.
To ensure better modularity and lightness, the motor has three parts. This motor can obtain higher density rates. It is also able to work even at constant pressure rates up to a maximum of 400 bar.
The TD motor also has a bigger capacity, making it capable of work with a wide range of heavy-duty machines, even with radial load on the shaft. Changing the eccentricity of the crankshaft allows changing of motor displacement. If the hydraulic circuit can avoid cavitation and back pressure, there will be a dynamic changing of motor displacement to avoid cavitation and back pressure.
