Abstract
Two methods of calculating the steady-state performance of small commutator permanent magnet DC motors are presented. The finite-element and classical methods have been used and compared with experimental data for an 8W DC motor with segmental permanent magnets. The results have revealed the accuracy and shortcomings of the two methods. The cogging torque calculated using the finite-element technique has been analyzed
