The impact of chopper control on armature current harmonics and core losses of permanent-magnet DC motors is analyzed. A computer-aided two-dimensional finite-element method is used to analyze the ...

This signifies that the reliability of the motor varies if we operate a DC permanent magnet motor at Point 1 Vs at Point 2 Vs at Point 3 as explained above and shown (Figure 1). In order to understand ...
