An Approach to DC Motor Modeling and Parameter Calculation Using Finite Element Analysis and Tensor Mathematics

This paper presents a general approach to DC motor modeling, using the finite element technique for maggnetic analysis, and tensor manipulation of network parameters to simulate the machine to the desired degree of complexity. Winding types and saturation of magnetic materials are taken into account. By including electrical and mechanical dynamic behaviour in the equations of state, this approach compactly manipulates the generalized machine mathematical modelto calculate transient response.
