The Summary of Induction Motor Torque Ripple Theories for Motor Torque Analysis

This paper is focused on the summary of induction motor torque ripple theories which is braked by dynamometer. The main aim of this paper explains the causes of the creations of harmonics components contained in the torque of the induction motor during steady state or dynamic motor operation. Furter point of this paper is separation of torque components between measured motor and dynamometer because the torque is measured by one sensor situated on the same coupled shaft common for both machines. Practical, it is the torque analysis with respect of motor and dynamometer topology and both machines are supplied by sinusoidal source only.
