Abstract

Permanent magnet (PM) brushless machines have been increasingly used in aircrafts and automobiles due to their light weight, small size, high efficiency, high reliability, variable speed operation and good dynamic performance. The permanent magnet brushless alternator has a permanent-magnet rotor, and the stator windings are wound such that the induced electromotive force (EMF) is trapezoidal. This paper presents the optimized design of a 3 kVA, 28 V permanent magnet brushless (PMBL) alternator for light combat aircraft application (LCA). The proposed alternator has two poles made of NdFeB and 12 stator slots. An analytical algorithm is developed for the design of PMBL alternator. The finite element analysis is carried in MAGNET 2D FEA-package for refining the design and performance evaluation of a three-phase permanent magnet brushless alternator.
