Abstract :
The aim of this study is to analyze both stator current and output torque spectra of a three-phase squirrel-cage induction machine in a hoisting winch system. These experiments are performed to show the influence of the shaft misalignment at different load and speed levels in motoring and braking modes. In this paper, it is observed that the influence of the shaft misalignment in the stator current and torque harmonics can be damped by increasing the load level for both motoring and braking modes.
