Proterial prototypes 100 kW motor using ferrite magnets

Proterial (previously Hitachi Metals, earlier post) announced that by optimizing the design of a motor that makes use of proprietary high-performance ferrite magnet NMF-15 (ferrite magnet motor), it’s potential to acquire the identical degree of output as an xEV drive motor that makes use of neodymium magnets.

Because of prototyping and evaluating an precise ferrite magnet motor primarily based on the simulation outcomes, Proterial has confirmed an output exceeding 100 kW—which will be utilized to his BEV and PHEV.

Simulation outcomes of drive motor for xEV and measured values of precise machine

	Neodymium magnet (baseline comparability)	Ferrite magnet (simulation consequence)	Use of ferrite magnet
– Neodymium magnet – Excessive efficiency ferrite magnet NMF-15G
Most rotation pace	10,000 rpm	15,000 rpm	15,000 rpm
Most output	110 kW	105 kW	102 kW

The ratio of xEVs within the world car parc will improve additional sooner or later. Together with this, the manufacturing quantity of neodymium magnets utilized in xEV drive motors and turbines is predicted to extend. However, neodymium magnets use neodymium, which is classed as a light-weight uncommon earth amongst uncommon earths, in addition to dysprosium and terbium, that are heavy uncommon earths whose assets are notably restricted.
