Abstract

A pneumatic motor assembly that includes a pneumatic motor, which is driven by a compressed gas. The pneumatic motor assembly has a magnet assembly that magnetically couples the pneumatic motor assembly to an implement. After having being used to drive a pneumatic motor, the gas, which has expanded and become colder, cools the magnet assembly The pneumatic motor assembly can thus enable the use to the implement at temperatures at which the magnet assembly would otherwise reach or exceed the maximum operating temperature of the magnet assembly. A flow induction system that includes the pneumatic motor assembly. A method of operating a pneumatic motor assembly that also cools a magnet assembly that is part of the pneumatic motor assembly.
