  • Abstract
    This paper examines the phenomenon of armature reaction and its effect on the torque per ampere characteristic or torque constant-kT-in brushless PM motors. In order to take account of saturation, finite element analysis is used together with the flux-MMF diagram. The technique of the flux-MMF diagram makes accurate prediction of instantaneous as well as average torque in both linear and saturated electric machines. The predicted results are presented along with the experimental data for a squarewave brushless DC and a sinewave brushless AC motor
