Abstract

Disclosed herein is a system including a motor comprising a rotor, a stator and a sealing assembly having at least one joint and a monolithic ceramic separator. Each joint of the sealing assembly is a chemical bond joint, and the monolithic ceramic separator is disposed in a gap between the rotor and the stator of the motor such that the sealing assembly hermetically isolates the rotor and the stator.
