Axial flux motors use the flux in axial direction to create a magnetic circuit linkage with the other components in the magnets. The main benefit of this machine being that it is thinner than the radial motors and can have a high torque to magnet densities if designed correctly. They are used in various automotive to other applications. Design of an axial flux motor is quite complicated. Conceptually the axial flux machine has a 3D magnetic circuit. A specific 3D analysis is necessary to analyze the design.

Axial flux permanent magnet machines are significantly more compact; the axial  length of the machine is much shorter compared to radial machines, which is often crucial for  built-in applications. The slim and lightweight structure results in a machine with a higher  power and torque density. But also, Axial Flux Permanent Magnet (AFPM) machines can  attain the highest energy efficiency of all electrical machines – refer White paper by Daan Moreels and Peter Leijnen.

Magnax www.magnax.com, machines have ben developed with following advantages:

  1. Increased efficiency (+96% efficiency vs. typical industry values of 84 to 92%).
  2. Reduced length (5 to 8 times shorter than traditional motors/generators).
  3. Reduced mass (2 to 5 times lighter than traditional motors / generators).
  4. ½ to ⅓ of materials required vs. other machines, which also results in lower costs).
