Permanent Magnet Synchronous Machine Rotor Vibration Measurement System

Abstract

Minimization of torque pulsation in Permanent Magnet Synchronous Machines has been the focus of significant research efforts during the last decades. However, accurate measurement systems able to monitor torque pulsation at the rotor shaft have not been developed so far.In this master thesis, a rotor vibration measurement system with an innovative on-line monitoring method has been developed. The measurements obtained from the designed prototype have been validated through Finite Element Analysis of the real machine. Finally, in order to produce a smoother output torque, a harmonic compensation strategy has been also developed and implemented in Simulink.
