“…2). This is due to the special stator structure with the magnetic bridge that offers a high flux control capability [15]. The use of permanent magnets in the HEFSM delays the magnetic saturation of the yoke which makes the excitation winding much more efficient and allows higher flux-linkages, while on the other hand, with no permanent magnets used, the yoke would have saturated at I exc = 3 A as shown in Fig.…”

“…To overcome these problems, many types of hybrid excited machines have been developed [9], and the PM-assisted wound field synchronous machine (PMa-WFSM) is one of them. In [10], a WFSM was designed for small electric-vehicle traction by inserting the permanent magnets into a predetermined position.…”

This paper presents the design and optimization of a novel wound field synchronous machine topology, in which permanent magnets (PMs) are introduced into the rotor slot opening with segment configuration for high quality output torque performance. The rotor shape of the proposed PM-assisted wound field synchronous machine with segment configuration is optimized for maximizing the average output torque and decreasing torque ripple under constant PM volume and motor size. The segment configuration can be benefit to improve the reluctance torque. In addition, it is further clarified that the assisted-PM can help to increase the field torque by enlarging the magnetizing synchronous reactance (X f ), as well as increasing airgap flux density. An optimal method combining Kriging method and genetic algorithm is applied for rotor shape optimization of proposed PM-assisted wound field synchronous machine (PMa-WFSM). Then, the 2-D finite-element analysis results, with the aid of JMAG-Designer, are used to confirm the validity. It is determined that the average output torque is improved by 31.66%, and keeps lower torque ripple without decreasing efficiency, increasing PM volume and motor size compared with those of the basic model. Finally, irreversible demagnetization and mises stress analysis verifies the reliability of the novel topology.

“…Hybrid Excitation Machines (HEM) combining PM and wound field machines have the potential to provide a more attractive solution for hybrid-electric marine vessels. Comprehensive reviews of HEM topologies are presented in [11][12][13][14][15]. By definition, a HEM is a type of machine that utilizes at least two excitation sources: the main common flux sources are PMs and excitation coils fed with DC current.…”

This paper evaluates the maximum torque capability of a hybrid excited synchronous machine in comparison with a conventional PM synchronous motor. The main focus of the paper is on the study of the effect of DC excitation magnetic flux on the saturation of the stator teeth, which limits the torque production capability of the hybrid machine. Magnetostatic and transient analyses are carried out for both motors. As expected the hybrid motor air gap flux controllability comes at the expense of reducing its torque density. The torque density reduction penalty is quantified and some hidden limitations and challenges of designing such a hybrid motor are revealed based on an in-depth analysis of the flux distribution within the machine.
