Summary

This tutorial demonstrated how to calculate a 3D magnetic flux field from magnets in a slotless permanent-magnet brushless motor.

Specifically, this tutorial has presented the following procedures:
  • Using the Finite Element Magnetic Vector Potential and the Permanent Magnet models
  • Defining materials and specifying the magnetic permeability
  • Reducing the number of magnetic poles by using antiperiodic conditions
  • Specifying a remanence magnetic flux to model permanent magnets
  • Visualizing the computed magnetic flux in a scalar scene
  • Visualizing the radial distribution of the magnetic flux using a line probe
