Analysis of Chopper-Fed DC Series Motor

The main problem in the analysis of chopper-fed dc series is due to the interdependence of armature induced voltage and the armature current and the fact that the relation between the two is nonlinear. The different aspects of analysis such as performance equations, methods of their solution, and the representation of nonlinear magnetization characteristics of the dc series motor are described. The calculated performance has been compared with the measured results.
