Evaluation of whirling speed of an induction motor

Abstract

The whirling speed in rotor dynamics, with reference to solid mechanics, is the velocity that excites the natural frequency of rotating object or assembly. Proper estimation of this whirling speed is one of the key factors that are to be considered at design stage of electrical machines as induction motors. This research paper deals with estimation of whirling speed of an induction motor. The work involves theoretical estimation of whirling speed and its validation using ANSYS.
