Optimization of power density for axial-flux machine through generalized sizing equations

With the evolution of various high power-density machines, it becomes important to optimize the power potential of machines of vastly different topologies with a variety of waveforms of back emf and current. The approach of this paper is based on the general-purpose sizing equations which permit the optimization method of machine power density to be applied to the axial-flux toroidal permanent-magnet (AFTPM) machine, and, furthermore, the power-production capabilities of the AFTPM machine and the well-known squirrel-cage induction machine are compared.
