Implementation of a non-metallic barrier in an electric motor

摘要

A motor (100) for use in a volatile environment (105) includes a rotor (170) exposed to the volatile environment, electronics (135) for rotating the rotor, an impervious ceramic barrier (175) separating the electronics and the rotor, and a flexible seal (145) for preventing the volatile environment from contacting the electronics and for minimizing vibratory and twisting loads upon the barrier to minimize damage to the barrier.
