Axial flux electrical motors are a sizzling matter lately. They aren’t new, as our electronics guru Jeffrey Jenkins identified in his deep dive into the axial flux world again in 2021. However modern designs from motor makers together with Flip and Orbis Electrical promise to open up new functions to EVs.
Mercedes-Owned YASA can be getting in on the axial flux motion—Highway & Observe experiences that the corporate not too long ago demonstrated an axial flux motor in its AMG GT XX idea automotive. Now YASA has launched some exceptional specs for its new motor, which it claims delivers “the best energy density ever recorded for an electrical motor in its class (and presumably for any motor).”
Tim Woolmer, CTO on the YASA cyss a brand new prototype motor it developed produces 550 kW (737 hp) and weighs solely 13.1 kg (29 lb). That works out to a really spectacular particular energy of 42 kW/kg. As Highway & Observe notes, “That’s extra energy than a normal Hellcat engine, in a chunk of apparatus you may decide up and maintain in your palms.”
In keeping with Woolmer, the brand new motor makes use of no unique supplies, needs to be mass-producible at 10,000-50,000 models per 12 months, and touts “insane cooling efficiency.” Steady energy output is “shut” to the height output utilizing solely commonplace cooling fluids.
YASA’s axial flux motors are inherently extra power-dense than the radial flux motors utilized in most EVs at present. As we famous in our protection of Orbis’s motor, the power to pack extra energy right into a smaller area might make electrification possible for brand spanking new lessons of automobiles. We have been most likely enthusiastic about cool stuff like tractors and building equipment, however Highway & Observe famous that “a single electrical motor with that a lot energy taking on such little area at a comparatively inconsequential weight can be an enormous assist for packaging, particularly for sports activities vehicles.”
