Pneumatic motor assembly, flow induction system using this pneumatic motor assembly, and method for operating pneumatic motor assembly

摘要

A pneumatic motor assembly including a pneumatic motor driven by compressed gas. The pneumatic motor assembly includes a magnet assembly that magnetically couples the pneumatic motor assembly to the instrument. After being used to drive a pneumatic motor, the expanded and cooler gas cools the magnet assembly. In this way, the pneumatic motor assembly can allow for use on instruments at temperatures that would otherwise cause the magnet assembly to reach or exceed its maximum operating temperature. A flow induction system including a 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.
