Failure Mode and Effect Analysis of Active Magnetic Bearings

Abstract

In the present research work Failure Mode and Effect Analysis (FMEA) of an Active Magnetic Bearing (AMB) has been presented. Various possible failures modes of AMBs and the corresponding effects of those failures on performance of AMBs have been identified. The identified failure modes of AMBs will facilitate designer to incorporate necessary design features that would prevent the occurrence of the failure. The severity, occurrence and detection of the failures modes are determined based on a rating scale of 1 to 5 to quantify the Risk Priority Number (RPN) of the failure modes. The methods to eliminate or reduce the high-risk-failure modes are proposed.
