ABSTRACT
Due to the great impact of inductance on performance of an electric machine, its values and characteristics were studied in this investigation. Special consideration is made to the machine’s pole number effects. The considered number of poles (Nr) were: 10, 11, 13 and 14. Two-dimensional finite element analysis method was applied in the calculations. The considered inductance parameters were: self, mutual, direct-axis and quadrature-axis inductance. Resulting magnetic flux value of the compared machine types at rated current were 6.19 mWb, 11.23 mWb, 8.98 mWb and 5.20 mWb, respectively. High value of flux linkage would incidentally influence the resulting electromagnetic outputs of the machine, positively. The results revealed that the compared machine types have comparable self-inductance values; although, the 13-pole machine type has marginally higher self-inductance value than its compared equivalents. The 11-pole (Nr=11) and 13-pole (Nr=13) machine types exhibit high fault-tolerance potential owing to its relatively larger inductance ratio. Nevertheless, the Nr=13 machine category has the largest amount of axes inductance and this has high electromagnetic saturation implications. It is also revealed that the resulting magnetic flux magnitudes and its matching inductances of the investigated machine are dependent upon its pole number and on the magnitude of supplied current.
