“…The stator core is made of a 0.5 mm silicon steel sheet, which can effectively reduce the stator eddy current loss and magnetic flux leakage [30]. In order to match the brushless design of EER, the stator is a combined stator with the same slot moment, tooth width, and yoke length, as shown in Figure 5.…”

Aiming at the problems of large excitation loss and low power generation efficiency of silicon rectifier generators and the unstable output voltage of permanent magnet (PM) generators, a hybrid excitation generator (HEG) with suspended brushless claw pole electrical excitation rotor (EER) and combined magnetic pole PM rotor is proposed in the present work. With only one fractional slot winding stator, the generator adopts PM field as the main magnetic field and electrical excitation field as the auxiliary magnetic field, which not only retains the advantages of high efficiency of PM generators but also effectively reduces excitation consumption. The main structure parameters and the design method were analyzed, and a simulation analysis of no-load magnetic field distribution and flux regulation ability was carried out using finite element software to verify the rationality of the hybrid excitation parallel magnetic circuit design. Moreover, the no-load, load, regulation, and voltage regulation characteristics of the designed generator were tested, and the results show that the designed generator has a wide range of voltage regulation, which can ensure stable output voltage under variable speed and load conditions.

“…In [13], a novel five-phase brushless DESM with symmetrical phase was presented to address the phase asymmetry shortcoming and improve the fault-tolerance capability due to a multiphase armature winding. In [14], a novel WFDSM with split-field winding was investigated to reduce the capacity of the field current regulator. In terms of S/G voltage, copper loss optimization based on a bidirectional converter is proposed to reduce the copper loss and the weight of the inverter/rectifier unit [15].…”

In this article, a four-phase dual armature-winding wound-field doubly salient machine with distributed field magnetomotive forces (DAW-WFDSM-DF) and corresponding double-redundant rectifier circuit are proposed to improve the electromagnetic performance of the traditional WFDSM in terms of the output voltage ripple, fault-tolerant capability and output capability. Firstly, due to the uniformly distributed field magnetomotive forces of the proposed machine, the more feasible stator/rotor pole combinations of the four-phase machine can be obtained and the influence of stator/rotor-pole combination on electromagnetic performance is investigated, especially for the fault-tolerant capability. Based on a multi-objective evaluation function including output capability, fault-tolerant capability and unbalanced magnetic forces, the 4N-stator-pole/3N-rotor-pole (4N /3N) and 4N /5N combinations are recommended. Then, considering that the fault-tolerant capability of 8/6-pole machine is poorer than that of 12/9-pole one, the 12/9-pole and 8/10-pole DAW-WFDSM-DFs are comparatively researched for taking as the representatives of 4N /3N and 4N /5N , including no-load and on-load characteristics and fault-tolerance performance under single winding open-circuit condition. Finally, as the 8/10-pole DAW-WFDSM-DF exhibits remarkably higher efficiency and stronger fault-tolerant capability than the 12/9-pole one, an 8/10-pole prototype is manufactured and tested to verify the analytical results. INDEX TERMS Fault-tolerant capability, stator/rotor pole combination, dual armature-winding, wound field doubly salient generator, distributed field magnetomotive forces, electromagnetic performance.
