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.

Formula 1 battery tech and light, ... Axial flux motors aren't exactly new—most optical drives use them, for example, but they're not very common in automotive applications.

Magnax, a company from Belgium, proposes a new yokeless axial flux electric motor that offers high power density, and a high efficiency of 98 percent.
