Result description
New synchronous reluctance motor for traction applications in EVs without any use of rare-earth metals. The design ensures the industrial feasibility for mass production, while focusing on the low cost of the manufacturing technologies employed. The motor will use low cost ferrite magnets instead of Neodymium-based permanent magnets for high power applications. Two power range motors are prototyped (200 kW and 75 kW). The powertrain and the power electronics will also be integrated, allowing its operation at different power levels.
Performance: The 200 kW permanent magnet synchronous reluctance machine will have 10 poles. Demagnetization of ferrite magnets has been limited to 1% through a complete design and optimization of both rotor (flux barriers) and stator to improve performance and high efficiency over a large region of the torque/speed map. Average operational efficiency is around 92%, while peak is about 95.5%. This concept will be scaled to 75 kW by modifying motor active length.
Scope: compared to existing solutions in the market, the solution developed aims to achieve the following figures: +30% specific torque; -50% direct motor losses; +50% power density in power electronics; and -15% production costs in mass production.
