Model of an Ironless Axial Flux Permanent Magnet Motor Based on the Field Produced by a Single Magnet
Résumé
The Lorentz force law is proposed as an alternative to the Maxwell stress tensor to calculate the torque of an ironless Axial Flux Permanent Magnet motor. This alternative allows calculating only the magnetic field produced by the magnets. A model of this magnetic field based on the field produced by one magnet, the superposition principle and geometric transformations is proposed. A method for calculating the magnetic field of this single magnet, inspired by finite elements, is proposed to reduce the calculation time. The method is validated by 3D Finite Element Analysis simulations and experimental measurements performed on a test bench.
