Abstract
An innovative numerical technique for the FEM calculation of the
electromagnetic torque in a rotating electric machine is presented, consisting in
an extension of the well-known Maxwell stress tensor method, applied to
circular paths that lie entirely in air. The mathematical model is introduced, and a
new element scheme is shown.
1 Introduction
There is a number of algorithms that allow numerical evaluation of mechanical
forces due to electromagnetic interaction. They are commonly used in FEM
analysis of power devices [l, 2, 31:
1, virtual works;
2. Maxwell stress tensor method (MST).
These methods are completely general: in other words, they are not specialized
for the evaluation of forces andlor of torques due to electromagnetic interaction
in particular devices, such as electric machines.
