Design and development of a user-friendly PC-based CAE software for the analysis of torque/speed/position controlled PM brushless DC motor drive system dynamics

A framework is formulated for the design and development of a user friendly CAE (computer aided engineering) package for drive system dynamics. The authors describe the design principles and algorithms of such a modular CAE package and its implementation on a personal computer. An effort has been made to fill the need for an interactive simulation to assess the torque ripple, losses, efficiency, torque and speed responses, and their bandwidth, as well as the suitability of the drive system for a specific application. One such CAE package, PMBD, has been developed, and key results using the package are presented to highlight the implemented features. Various user friendly features and dynamic and steady-state analysis results are described in detail.<
