Abstract

Studying a new ferrite magnet machine using electronic commutation, the authors have sought a method to determine the variation of the inductances and torque with the relative rotor/stator position. The method adopted uses the direct resolution of the finite difference equation of the potential vector. Subsequently it is shown how the properties and characteristic variables of the machine can be deduced from the numerical solution of the equation. Finally the results obtained are compared with those obtained experimentally.
