Axial-flux PM motor designer app (3.3–50 kW)

Design a YASA, TORUS or single-sided axial-flux motor with multi-slice FEA, and compare it with IPMSM, induction and SRM motors.

YASA axial-flux motor: stator segments with phase coils, rotor disc with 16 magnet poles, gap field over the disc and a finite-element flux plot
15 kW YASA design: stator, rotor disc and multi-slice FEA flux
Bar charts of active mass, torque density and best efficiency for three axial-flux topologies and radial IPMSM, induction and SRM motors
Axial-flux topologies vs radial motors, all auto-sized in the apps for 15 kW

Aim

Size an axial-flux permanent-magnet traction motor from its disc geometry, magnets and winding, check it with quasi-3-D finite-element analysis, and compare the three axial-flux topologies with radial IPMSM, induction and switched reluctance motors at the same rating.

What you’ll learn

  • Axial-flux topologies: YASA, TORUS-NS and single-sided
  • Concentrated and toroidal windings, slot/pole combinations
  • Multi-slice (quasi-3-D) FEA: back-EMF, cogging and axial pull
  • Axial-flux vs IPMSM vs induction vs SRM for EV traction
