Hydraulic rotary piston motors - Powerful drive technology in a compact form

Hydraulic rotary piston motors, such as the Wankel motor, offer a number of technical advantages that make them particularly suitable for use in mobile machines and industrial applications. Thanks to their compact design and low weight, they can be easily integrated into confined installation spaces. The design with only a few moving parts and the absence of a valve control unit not only reduces the installation space, but also minimizes maintenance requirements.

An outstanding feature is the smooth running of the motors. The continuously rotating movement enables complete balancing, which significantly reduces vibrations even at high speeds. This leads to an improved service life of the components and increased operating comfort.

Rotary piston motors deliver a constantly uniform torque, as no oscillating masses need to be moved. In conjunction with the hydraulic power transmission, precise and infinitely variable control of speed and force is possible. The efficiency remains high, as hydraulic media enable efficient power transmission.
Another advantage is the high level of flexibility during installation. Hydraulic lines can be routed freely, allowing the motors to be positioned anywhere in the system - a significant advantage when designing complex systems.

These motors also impress with their high power density. Despite their compact dimensions, large forces and outputs can be achieved, which makes them particularly attractive for applications with limited installation space.

In the field of hydraulics, rotary piston motors offer a technically convincing solution: powerful, compact, low-vibration and precisely controllable - ideal for demanding applications with high power requirements and limited space.
