Ironless and leakage free voice-coil motor made of bonded magnets.

Résumé

This paper reminds the drawbacks of classical voice-coil motors and presents a way to improve them. Two ironless and leakage free structures are presented, one using traditional sintered magnets and other one using bonded magnets, giving the pros and cons of each solution. A 2-D analytical model using the Coulombian approach is used to calculate and compare the performances of both structures. Then, in order to evaluate the relevance of the 2-D model for magnet rings, a comparison is doe with a 3-D analytical model for several radii of rings.
