WHYan organization specializing in axial flux electrical motor expertise, has introduced an unofficial world file for electrical motor energy density with its newest prototype. Latest testing of a 12.7 kg axial flux motor prototype yielded a short-term peak output of 750 kW, leading to a recorded energy density of 59 kW/kg.
This breaks YASA’s personal earlier mark of 42 kW/kg, achieved with a 13.1 kg prototype that peaked at 550 kW earlier in the summertime of 2025. The corporate says the continual energy output for the brand new motor is estimated to be between 350 kW and 400 kW.
Extra: A better have a look at axial flux motors
The design makes use of no unique supplies and is engineered for compactness and scalability. YASA says the prototype employs precision engineering, superior thermal administration, and optimized packaging to realize these outcomes.
The motor has been developed and examined at YASA’s Oxford Innovation Centre, with assist from the Superior Propulsion Centre in the UK. YASA experiences that the prototype is just not a simulation or conceptual design, however a completely operational motor presently present process prolonged dynamometer testing.
“The early outcomes are extraordinarily encouraging,” stated Simon Odling, Chief of New Expertise, YASA.”The motor’s efficiency on the dyno has exceeded even our most optimistic simulations. In addition to its unimaginable peak energy and total energy density, we estimate this new motor will be capable to ship all-important steady energy within the area of 350 kW-400 kW. That is actual {hardware}, in actual life, delivering actual information – and it’s performing superbly.”
YASA targets the high-performance automotive sector with this expertise, aiming to supply compact, environment friendly electrical propulsion programs for premium electrical autos.
