Abstract
For inverter driven motors, it is important to investigate the coil voltage distribution for interturn insulation design. In this paper we researched form-wound coil voltages against steep-fronted surge. We present the results of investigations of the equivalent circuit of the windings, measurement of coil voltages and voltages-to-ground, simulation of them by EMTP (Electromagnetic Transients Program) and formulation of a numerical expression for the circuit constants
