Abstract :
The paper presents a two-dimensional saturation model for DC traction motors. Two look-up tables are employed, which are the measured saturation curves for the main poles and interpoles respectively. Besides the saturation caused by field currents, an algorithm is derived to account for the flux weakening caused by armature reaction. The effects of saturation on all inductance parameters are presented, and variations of the armature inductance with both main pole saturation and interpole saturation are modelled. A Simulink motor model is presented to implement the above features in simulation, and is used as a visualisation simulator for DC traction motors. This model has been saved as a Simulink library for further applications in investigating commutation process of DC traction motors
