Pneumatic motors are safe and robust drive systems, that are used when a powerful and overload-safe drive is required.
The characteristics of airmotors are shown in Waste Water Drain Renovation.
An indestructible airmotor drives the milling head of a renovation robot. This robust and small pneumatic motor performs under extreme conditions (dirt, water, etc.) while achieving high power density and reliability. If overloaded the pneumatic motor will stop and will not be damaged. When the load is removed it can run immediately again. This can occur repeatedly even in high duty cycles. The speed can be easliy changed by the air pressure and volume. The pneumatic motor operates within an extreme torque range.
