2016. Optimized electromagnetic and manufacturing design for a BLDC-motor substituting rare earth magnets. 2016 6th International Electric Drives Production Conference (EDPC). :207–210.
Substituting neodymium with ferrite based magnets comes with the penalty of significant reduced magnetic field energy. Several possibilities to compensate for the negative effects of a lower remanence and coercivity provided by ferrite magnets are presented and finally combined into the development of a new kind of BLDC-machine design. The new design is compared to a conventional machine on the application example of an electric 800 W/48 V automotive coolant pump.
