 Magnax Axial Flux Motors come with peak power densities up to 15 kW/kg (7,5 kW/kg nominal). 


The Magnax Axial Flux concept enables the combined use of the following best-in-class practices into one machine:

→ Dual permanent magnet rotors, for the highest possible torque-to-weight ratio.

  • → Yokeless stator, for the shortest possible flux paths and a lower overall weight.

  • → Rectangular section copper wire, for the highest possible copper fill factor (90%).

  • → Concentrated windings, for the lowest possible copper losses (no coil overhangs).

  • → Grain-oriented electrical steel, lowering the core losses by as much as 85%.

  • → patented system for cooling the windings, for the lowest possible stator temperatures.
