Insulation considerations and qualifications for form-wound air-core armature windings in high-frequency electrical machines
… will first be summarized. The machine and drive system will then be examined in a system context to determine the possibility of voltage overshoot at the motor terminals caused by a variable frequency drive along a transmission line. Based on simulation results, recommendations for future work in …
