Could the ”tugging force” from an axial flux motor damage the bearings?

Aug 21, 2026 498

The stator and rotor are separated by a sub-millimeter air gap, and there is an axial attractive force of several metric tons between the magnets on both sides and the iron core. If the force on the air gap becomes uneven, the attractive force on one side increases exponentially, posing a severe challenge to the rigidity of the bearings and the housing.
