Permanent magnet price volatility is an ongoing issue that
affects many industrial sectors worldwide, dictating the costs of
the final product by a substantial degree. This fluctuation can
be attributed to a large concentration of NdFeB magnet production
and material sourcing occurring in concentrated geopolitical
areas, thus motivating institutions and governments to look elsewhere
for magnet material for various applications. The work
presented in this paper aims to determine the viability of recycled
permanent magnets in electric machines used within the automotive
industry. Magnet recycling incentives are presented, along
with the two main routes for magnet reprocessing. They are
briefly compared to present the route selected within this study.
The recycled magnets used in this study are characterised such
that relevant parameters are extracted for further analyses. A P2
hybrid electric vehicle is modelled and its energy management
system presented, being an Equivalent Consumption Minimisation
Strategy. The performance evaluation of a baseline machine
at component level is performed, with its affect on vehicle performance
quantified, followed by the recycled magnet machine’s
characterisation and subsequent performance evaluation at vehicle
level. The recycled magnets inhibit a minor efficiency degradation
at component level, leading to a performance degradation
of about 0.11% at vehicle level. [-]
