Fault Analysis and Remedial Strategies on a Fault-Tolerant Motor Drive with Redundancy

Abstract

Fault-tolerant motor drives are required in a range of safety-critical applications. Using a special motor design and an appropriate inverter topology, brushless permanent magnet AC motor drives can have an effective fault-tolerant capability. Although a single motor fault-tolerant drive system may be sufficient in many critical applications, a higher… (More)
