This paper discusses the design of a fault tolerant electric motor for an aircraft main engine fuel pump. The motor in question is a four phase fault tolerant motor with separated windings and a six pole permanent magnet rotor. Methods of reducing machine losses in both the rotor and stator are introduced and discussed. The methods used to calculate rotor eddy current losses are examined. 3D finite element, 2D finite element time-stepping and 2D finite element harmonic methods are discussed and the differences between them and the results they produce investigated. Conclusions are drawn about the accuracy of the results produced and how the methods in question will help the machine designer. © 2005 IEEE.
