Propagation of Inverter Surge and Voltage Distribution in Motor Winding

This paper states an investigated result of motor winding voltages driven by an inverter including propagation characteristic of a cable. We developed a cable surge analysis method that takes into account a frequency dependency of a dielectric characteristic of cable material and mutual induction between cable wires. A motor winding model considering a frequency dependency of a winding impedance and mutual coupling between slots is also proposed.
