Magnet Materials – Technical Resources
- Predict the surface flux density of a Permanent Magnet Rotor or Flywheel - with acknowledgements to Dr. Stefano Tizianel, Technical Director at Laboratorio Elettrofisico Eng in Italy, and inventor of the sinewave magnetization fixture, and SAT transverse flux magnetization coil. (Note: In the formula, Distribution is H for Halbach (sine wave) and R for Radial. In "R" condition you can consider the magnet covering the entire pole (Angle=1) or a partial pole (for example, Angle 0.5 if the magnets cover only half a pole, when, in other words, there is a large distance between magnets). The Position is the radius at which the flux density is calculated and plotted. The Position radius should be inside the air gap. (The Stator and Rotor are considered to have infinite permeability, and therefore not saturated.) The Stator and Rotor can be inverted by making Rs smaller than Rr; the value of Rm, must be between Rs and Rr.)
