Abstract
The paper presents a technique for determining the influence of the finite axial length of the permanent magnets on the rotor loss of modular brushless AC machines. The technique is employed to quantify the effectiveness of axially segmenting the permanent magnets of 4-phase, 8-slot, 10-pole and 5-phase, 10-slot, 12-pole brushless machines, which have been designed to meet the performance requirements of an electromechanical actuator for a ´more-electric´ aircraft.
