At High Speed, Will the Magnets of Axial Flux Motors Be Flung Out by Centrifugal Force?

Aug 30, 2026 500

The effective magnetic force acts at the outer-diameter edge, so at the same speed the magnets endure far higher centrifugal stress than in a slender radial motor. Under high-speed conditions, how the magnets are firmly fixed to the rotor disc is a key point of structural design.
