Two dimensional model of a permanent magnet spur gear

This paper extends an analysis method developed for a radial magnetized spur gear. The extension describes how a parallel magnetized spur gear can be modeled analytically. The analytical method for a parallel magnetized gear is verified with the finite element method, which showed good agreements. The results with the parallel magnetized are also compared with results from the previous developed analytical method for radial magnetized gear, and the parallel magnetized version turned out to give a better performance. A test model was also built to verify the theoretical calculations.
