The lack of a yoke and locating the magnets away from the central axis result in higher power-to-weight ratios than equivalent radial flux motors. The EVOA E1 and Acel outboards use axial flux motors.

New axial-flux traction motor ditches heavy iron and copper stator ... Chorus Meshcon motor coming soon in WheelTug aircraft nose gear. Lighter stators would seem to make Infinitum motors ...

Axial flux motors also have benefits when it comes to ... you can just use off-the-shelf gear and hack it to make it work. Here, we support both methods.
