A HYBRID TECHNIQUE FOR ELECTROMAGNETIC TORQUE AND FORCE ANALYSIS OF ELECTRIC MACHINES

In electric machines, the electromagnetic torques and forces are devel oped as a result of the interaction of the magnetic fields. These forc es can be computed from the results of field analysis, using numerical or analytical methods. Describes a hybrid technique, which is suitabl e for the calculation and analysis of electromagnetic torques and forc es. This method exploits the advantages of numerical and analytical me thods for field analysis, and thus provides a more efficient and effec tive tool for torque/force computation, in comparison with traditional methods. The computational examples presented show that the method is particularly useful for accurate prediction of the electromagnetic to rque and unbalanced magnetic pull in electric machines.
