Abstract :
Based on the concept of power converter fed machines (CFMs), high power density machines with nonsinusoidal current and back EMF waveforms are attracting more and more research interest. In this paper, a novel type of axial flux circumferential current permanent magnet (AFCC) machine topology is introduced. A sizing equation analysis, finite element analysis, optimization of parameters, performance simulation, details of the prototype and test data are included. In addition, a comparison of the power densities between the AFCC machine and the traditional induction machine based on the sizing and power density equations is also provided. Alternative manufacturing arrangements and the method to reduce torque ripple are discussed.
