Abstract
This paper describes design modifications and optimization of a brush permanent magnet DC motor. The test
model was optimized using the analytical method via an equivalent circuit, and the final model simulation was
performed using the finite element method (FEM). For the optimization method, a central composite design of
the response surface analysis was used, and torque and current ripples were analyzed using 2-D FEM. The
back-to-back test method was used to evaluate the developed model to minimize the burden on the construction
of the test equipment. The test results were validated through a comparison of the analysis results.
