It doesn't make that a good idea. Armature losses are proportional to torque squared - doesn't matter if it is radial or axial design. That's why all the EVs today have gear boxes with ratios like 13:1. Get rid of that gearbox and the steady-state losses go up with the square of that ratio. Then there are the issues of sprung mass, and where to put the mechanical brakes. | ||

YASA claims their integrated brake/wheel motor is lighter than comparable (supercar) disc brake systems. | ||

>gear boxes with ratios like 13:1. you add planetary gears >sprung mass you can integrate all into one hub (breaks, bearings, gears etc) and it weights pretty much the same. what you gain is more space for a bigger battery, torque vectoring, no loss on diff and CVs | ||
