Due to their compact design, modular construction and high efficiency, axial flux motors are considered a promising alternative to classic radial flux machines—especially where installation space is limited or high performance requirements exist. However, there are physical limits at higher corner and maximum rotor speeds: Among other things, efficiency decreases due to pronounced eddy current losses in the stator windings.
