Study of triangular winding alternators

This study examines a three-dimensional magnetic flux machine as a replacement for the alternator of a car. Such a machine could be placed in the clutch bell housing. The windings have a triangular shape so that the end windings take up less space. This single-phase machine is very thin. Both triangular and rectangular magnet shapes have been studied for the rotor. Here, we present two models for studying the behavior of such machines: an analytical no-leakage model and a more complete finite-element model. We use both models to describe a homopolar machine and a heteropolar machine and compare them to conventional machines with rectangular windings and rectangular magnets
