Comparison of Hybrid Excitation Synchronous Motor with Sinusoidal and Non-Sinusoidal Back-EMF

Hybrid excited synchronous machines are getting used wider and have perspectives for being used in many spheres where there is a need in efficient machine with magnetic flux control ability, especially, while prices on permanent magnets are getting higher. Models of synchronous machines with hybrid excitation allows to simulate different operation modes itself and create more complex models including this type of machine. For accurate analysis of hybrid excitation synchronous motor and it`s drive control it is significant to have an accurate model. This paper deals with comparison of synchronous machine with hybrid excitation with non-sinusoidal and sinusoidal back-emf.
