This leads to a reduction of fuel consumption which has also positive effect on emissions. One possibility how to reach this aim is to replace hydraulic and pneumatic system with an electrical power system. Because many on-board electrical loads are in the form of electrical drives, the special attention is given to electric motors and their electronic speed controllers / power converters. Furthermore, electric motors suitable for traction/propulsion are presented. Moreover, the various types of starter/generators suitable for on-board utilisation are compared in the paper. Keywords: electric machines; starter-generators; more electric aircraft 1. INTRODUCTION There is a strict international requirement for global emission reduction. In aviation sector, the projects like Clean Sky and ICAO Global Coalition for Sustainable Aviation aim to reduce noise and pollution [1].
