WHEEL MOTORS
HIGH STARTING TORQUE
The radial piston design ensures very high starting torque efficiencies,
especially at high pressures where they are most required in mobile
applications. Efficiency is typically > 94% at 400 bar.The maximum torque requirement for wheel motor applications generally occurs with the vehicle al standstill or at low speeds, for example, during acceleration from stand-still or when overcoming an obstacle or slope.
High starting torque in the hydraulic motors therefore means better vehicle performance, less energy wastage and heat generation, especially with frequent stop-start work cycles.
High starting torque enables larger obstacles and steeper slopes to be overcome.
WIDE SPEED RANGE
SAI motors have some of the widest specific speed ranges (max speed: min
speed ratio) of any hydraulic motor, due to their very good low speed
characteristics (the motors remain sensitive to flows down 0.5 l/min) and
higher than average max. speeds for motors of similar design.HIGH VOLUMETRIC EFFICIENCY
The motors have very high volumetric efficiencies in all operating conditions
(typically>99%). The seal design used throughout the motors ensures that the
volumetric efficiency is not affected if component become worn with use. The
combination of high volumetric and mechanical efficiencies means that the
motors generate less heat enabling smaller heat exchangers to be installed
or, in certain cases, enabling then to be completely eliminated.
