Abstract: In order to diminish the frictional force between the vane tips and the stators and achieve the clearance compensation, a novel double-stator multi-speed motor with roller vane tips was proposed, in which the vane tips roll instead of sliding on the stators. The vane tip rollers are forced on the inner and outer stators under centrifugal force and the hydraulic pressure, thus forming oil tight working chambers. To demonstrate the mechanism of its sealing, force analysis was carried out on the rollers, and the experimental platform was set up. It turned out that the roller-vane structure could acquire rolling while maintain the volumetric efficiency, which transfer the contradictions between the vane tips and the stator curves and provides a new idea for designing the double-stator multi-speed motor.

Key words: turn and control of fluid, roller tip-vane structure, double-stator multi-motor, clearance compensation, volumetric efficiency
