Abstract

The aim of this work is to present and discuss an original way to analyze a synchronous permanent magnet micro-motor (SPMM) for design purposes. The analysis of the magnetic field distribution in the motor, whose geometry would require a 3D modeling, is instead carried out with the aid of two 2D finite-element (FE) simulations: one axisymmetric and one on the cross-section or transverse plane. To validate the suitability of the proposed method for torque computation, a 3D-field solution is also presented. Computed results of distribution of magnetic induction, as well as the torque developed by the motor in both 2D and 3D simulations, have shown good agreement with measurements in a prototype machine
