We present a new topology of hybrid excitation synchronous machine (HESM) and describe operational principles and features of the new configuration. Using the radial/axial distribution of the magnetic field, we develop an equivalent magnetic circuit model. We obtain magnetic flux, flux density, and induced voltage with various electrical magnetomotive forces by calculating the nonlinear magnetic circuit...
Static excitation system of synchronous motor by using the compounding principle is considered in this work. The magnetic induction distribution of salient pole synchronous machine is nonsinusoidal in air gap and from the higher harmonics of a magnetic field the most expressed is the third harmonic. Therefore the auxiliary winding can be placed in armature of a machine to use the third harmonic energy...
