Computer-aided modeling and experimental verification of the performance of power conditioner operated permanent magnet brushless dc motors including rotor damping effects
In this second in a set of three companion papers on the modeling of permanent magnet brushless dc motors, a model is presented here for computer-aided prediction of performance of such motors, including effects of rotor damping due to metallic retainment sleeves. Here, the computer generated parameters given in the first of these companion papers were used in a model formulated entirely in the natural abc frame of reference. Thus, one avoids the complication of transformation from one frame of reference to another, and hence this approach enables one to incorporate all significant harmonic effects due to any saliency and slotting. The development of the model in the natural abc frame of reference also facilitates the integration of the machine and the electronic power conditioner into one all encompassing equivalent network model for the entire brushless dc motor system. The validity of the model was verified by applying it to the prediction of the performance of a 15 hp, 120 V, 6-pole, samarium-cobalt permanent magnet brushless dc motor, and comparing the digital simulation results with the corresponding test data for this motor system. Very good agreements between the simulation and test results were achieved, including predicted power outputs and waveforms of currents and voltages throughout the machine-power conditioner system.
