YASA axial flux electric motor becomes the world's most power dense

Amazing stuff! Looks like electric motors are becoming more powerful almost by the month.

"Since 2021, YASA has been a wholly owned subsidiary of Mercedes-Benz Group"

"... YASA announced its latest prototype motor breakthrough this week, and this time around, it's managed to shave off close to half an ounce of weight while boosting power by over 33%.

More precisely, YASA's latest prototype axial flux motor weighs in at 12.7 kg (28 lb) while firing out a peak power of 750 kW (1,006 hp), pinning down a new unofficial world record power density of 59 kW/kg, a full 40% more than the already massive figure it achieved just a few calendar flips ago. ...

As for what the YASA prototype motor can achieve in continuous operation, YASA's team estimates that figure between 350 and 400 kW (469 and 536 hp), which gives it a 27.6 kW/kg continuous power density that lands greater than most motors' peak power densities. In fact, it's double a couple of those aforementioned figures above. ..."

Conifer Motors builds motors by replacing rare earth magnets with iron magnets

Good news!

"... California-based Conifer Motors is trying to break that stranglehold by simply cutting rare earth materials out of the equation and making EV motors from one of the most abundant materials on Earth: iron. ...

Most electric motors are radial-flux. That is, they are cylindrical with magnets spinning around a central shaft, which makes them simple, reliable and scalable. Axial flux, on the other hand, is more like a flat disk. Like a tuna can (axial) instead of a soda can (radial). These motors generally run lower RPMs and produce more torque due to their wider radius and shorter magnetic path. ...

Conifer isn't trying to break into the electric car market with these new iron-based axial-flux motors. Instead, the company is focusing on smaller 1 to 25-hp (0.75-18.65-kW) electric motor applications for stuff like HVAC fans and pumps, tools and equipment, and even fun stuff like in-wheel motor designs for small electric vehicles and off-road toys – think scooters, ATVs, and urban delivery vehicles.  ...

Conifer's in-wheel design simplifies everything: no axles, no differentials, and no other powertrain bits, making the entire vehicle project less complex and less expensive with less energy loss in transmissions, CV joints and the like. It also has the potential for better traction control systems, as each drive wheel would have its own motor. ..."
