Script to create an hypocyclic helical rotor inside a stator. This configuration is also known as a Moineau pump.

General Usage Instructions

Adjust the entered parameters in the dialog box to customize your own hypocyclic helical rotor and stator. The rotor will typically need a shaft added afterward, consistent with your drive mechanism design.

The stator generated is actually the solid model of the stator cavity. As the stator is frequently molded out of silicone, this allows the user to use the generated model for creating the mold tool. This feature can also be used to create the overall stator geometry by cutting it via Boolean operation from whatever external pump geometry you design.

Pump cavity volume and drive eccentricity decrease with more lobes.
