A STARTER-GENERATOR FOR HELICOPTERS

Abstract

Comparative electromagnetic calculations of a commercial starter-generator and a nonsalient-pole-stator starter-generator are made. The nonsalient-pole-stator starter-generator magnetic fields are shown in start-up and generator rated conditions. The electromagnetic calculation technique is verified and confirmed with experimentally investigated nonsalient-pole-stator machines of other types.
