Abstract

In this paper, we examine and compare the performance of a generator design optimized using additively manufactured NdFeB - SmFeN in nylon-polymer-bonded permanent magnets (PMs) against a generator design with conventional NdFeB sintered PMs. To realise this, a commercially available 15-kW wind generator's rotor is re-optimized using both addi- tively manufactured and sintered NdFeB magnets using simple geometric parametrization that allowed for two specific magnet shapes, namely arc-shape and crown-shaped designs. Results showed that for a similar generator performance, the designs with additively manufactured bonded PMs are more cost-competitive in terms of the estimated PM material cost and also have negligible eddy current magnet losses.
