Abstract :

The effect of design variables on the average torque are investigated in this study. The investigated parameters include the machine’s aspect ratio, permanent magnet thickness, rotor radial thickness, outer-stator tooth width, inner- and outer-rotor iron width / rotor pitch ratio, slot opening / stator pitch ratio, inner-stator back-iron size and outer-stator back-iron size. Finite element analysis (FEA) is used in prediction of the results. The simulation is also conducted under different maximum currents of the supplied alternating current (AC) stator phase excitation. The results reveal that the output torque of the analyzed machine is dependent on the geometry of the analyzed machine model; hence an optimal value of the geometries is indispensable.
