Abstract:
Electrically Excited Synchronous Machines (EESM) is one of the strong candidates to solve the supply chain risks, costs and sustainability issues due to the Rare-Earth magnets presently used in almost 90% of the Traction Motors. However, for long, EESM presented lower Performances, especially in terms of Torque density: approximately 10 to 20% bigger volume required combined with Lower Efficiency (up to 3%) compare to Radial Flux Interior Permanent Magnets solutions that are considered Benchmark. YEESMA is currently developing its own Proprietary solution consisting on an Axial Flux Electrically Excited Solutions. Such Dual Rotor, Single Stator helps solving the Packaging and Performances challenges: up to 20% Torque volumetric density, with more than 50% Cost reduction AND 60% Higher Sustainability Index.
Novel Manufacturing solutions will also be presented to reduce Axial Flux machines assembly challenges. Inverter Phase current is also significantly reduced thank to a Unity Power Factor and participates to the 50% Cost reduction mentioned above.
In this webinar, an innovative Electric Machine will be presented which well addresses several Applications ranging from ~5kW to 350 kW, such as 2-Wheelers, Marine, Passenger Cars and Commercial Vehicles will be presented the e-Mobility requirements, naming Cost, Performances and Sustainability index.
