The paper describes the design, analysis, simulation, modeling and control implementation of a high-torque, low-speed, multiphase, permanent magnet, brushless dc machine. The main focus is on issues regarding the high-level modeling, comprised of a transient model, in conjunction with corresponding experimental evaluation. The general assumption of ideal rectangular current waveforms for brushless-dc machines is not encountered in practice; the existing distortions can be modeled by incorporating mutual inductance and armature reaction in order to avoid erroneous control strategy development. Analyses are made to put together modeling efforts with the expected behavior so as to build a model of the expected behavior so realistic simulation results can be verified. Coherent and consistent results were observed by comparing simulation and experimentation. A digital signal processing (DSP) system control was developed to implement the strategies that corroborate the work.
