“…where the area can be designed to establish a saturation flux (φ s ) for a desired field current (assumed to be at max φ FW (I FW )). [36], and Pang et al [92]. A common solution is to place the PM beside the air gap similar to a PM bridge between the surfaces of two classical FW poles.…”

“…(a) At high fields, the iron is saturated and all PM fluxes go to the stator. (b) At low field currents, there is a leakage flux from the PM through the iron of the electromagnets.Designs using parallel flux paths have been studied by Yamazaki et al[26,89,90], Hosoi et al[91], Ployard et al[35], Hwang et al[28], Wardach et al[36], and Pang et al[92]. A common solution is to place the PM beside the air gap similar to a PM bridge between the surfaces of two classical FW poles.…”

Hybrid excitation is a technology that combines the advantages of field windings and permanent magnets for inducing magnetic flux. This article studies the benefits of hybrid excitation and provides an outlook on their possible applications, such as wind power generators and electric vehicle motors. Compared to permanent magnet-based machines, hybrid excitation gives a variable flux while still using the advantage of the permanent magnets for a portion of the flux. This article also looks into some different categories of machines developed for hybrid excitation. The categories are based on the reluctance circuit, the relative geometrical location of the field windings relative to the permanent magnets, or the placement of the excitation system.
