This paper presents a dynamic model for mechanical
\r\nloads of an electric drive, including angular misalignment and
\r\nincluding load unbalance. The misalignment model represents the
\r\neffects of the universal joint between the motor and the mechanical
\r\nload. Simulation results are presented for an induction motor driving
\r\na mechanical load with angular misalignment for both flexible and
\r\nrigid coupling. The models presented are very useful in the study of
\r\nmechanical fault detection in induction motors, using mechanical and
\r\nelectrical signals already available in a drive system, such as speed,
\r\ntorque and stator currents.<\/p>\r\n","references":"
