Model of an Ironless Axial Flux Permanent Magnet Motor Based on the Field Produced by a Single Magnet

The Lorentz force law is proposed as an alternative to the Maxwell stress tensor calculate torque of ironless axial flux permanent magnet (AFPM) motor. This allows calculating only magnetic field produced by magnets. A model this based on one magnet, superposition principle, and geometric transformations proposed. method for single inspired finite elements, reduce calculation time. validated 3-D element analysis (3-D FEA) simulations experimental measurements performed a test bench.
