description: Implementing a universal high frequency induction machine model for arbitrary stator winding connections is crucial to determine and investigate the electromagnetic interference (EMI) issues concerning stator winding reflected wave overvoltage and bearing discharge current. It is also fundamental in determining proper motor dielectric insulation and optimal design of dv/dt filters. To design and characterize high frequency induction machine model accurately, the machine’s Differential Mode (DM) and Common Mode (CM) impedance characteristics should be analysed within the interested frequency range. The high frequency machine model should be able to represent all the possible stator winding connections (e.g., Y or Delta connections) to create a comprehensive universal high frequency machine model. In this thesis, a 7.5 HP dual-voltage 9-terminal/lead Baldor induction machine is selected for the high frequency machine modeling study due to its availability of different stator winding configurations. There are four possible types of stator winding connections of the Baldor induction machine as Single Y, Single Delta, Series Y, and Parallel Y winding configurations. Considering the machine high frequency phenomena under study and the limitation of the measurement equipment (impedance analyzer or frequency response analyzer), this thesis is focused on high frequency machine model with frequencies up to 10 MHz. The frequency ranges are subdivided into three sections: low frequencies (100 Hz – 10 kHz), mid frequencies (10 kHz – 500 kHz), and high frequencies (500 kHz – 10 MHz). The considered high frequency range is limited up to 10 MHz due to the complicated harmonics present above that limit generated by the output-controlled AC (Alternative Current) step voltages of the motor drive. There are also modeling complications with the capacitive and inductive couplings, extracted from 2D finite element simulations, as well as analytically estimated resistive winding losses in …
