  • Abstract
    The majority of all shaft failures are caused by a combination of various stresses which act upon the rotor assembly. As long as they are kept within the intended design and application limits, shaft failures should not occur during the expected life of the motor. This article provides the reader the methodology to conduct an analysis that will properly identify failures and hopefully take the necessary steps to eliminate them
