Like all Hense rotary vane motors, rotary vane motors in the HSS series are designed according to the rotary vane principle. The drive shaft has axial and radial plain bearings in coated bushes. The coating used is tribologically optimized and ensures low wear. Sufficient lubrication of the bearing points is ensured by the supplied hydraulic oil. To reduce the internal friction of the motor, the hydraulic separation of the working chambers in this series is partly achieved by means of pressure and viscosity-dependent throttle sections.
HSS motors are ideal for generating oscillating swivel movements in the frequency range with small angular amplitudes in controlled systems. The HSS series is therefore recommended for use whenever semi-dynamic torsion tests need to be carried out reliably and cost-effectively.
Servo-hydraulic hydraulic oscillator
In conjunction with other high-quality components, such as servo valves, pulsation accumulators and high-resolution angle measurement systems, the hydraulic oscillator is designed to generate alternating torsional loads.
We offer customized solutions for a wide range of applications. Our qualified team will be happy to advise you on design and realization.

Product overview
Swivel motors HSS
These drives are preferably used in controlled systems with oscillating swivel movements in the low-frequency range. They close the technological gap between conventional swivel motors for industrial applications and the HSH series.
Swivel motors HSH
HSH motors are preferably used in highly dynamically controlled systems with oscillating swivel movements in which disturbance variables such as natural friction and the stick-slip effect must be reduced to a minimum and the highest number of load cycles must be achieved.
