“…For aerospace applications, the WRSM is a consolidated and well-proven option for the generator in more electric aircraft [16]. As reported in [15], by using the integrated damper cage, the output voltage total harmonic distortion performance of the WRSM can be improved to 1% level, which shows a high output power quality.…”

“…Due to the flexible flux regulation capability and no rare-earth PM material structure, WRSM have been applied in electrical vehicles (EVs) [5][6][7][8][9][10], power generation [11][12][13][14] and aerospace [15,16]. In order to fully utilize the additional control freedom of the DC winding, deadbeat direct torque and flux control was proposed in [8], which can achieve the unity power factor operation and reduce both copper loss and iron loss.…”

In order to analyze the DC winding induced voltage in the wound-rotor synchronous machine, this paper uses the air-gap field modulation principle to investigate its operation mechanism and harmonic order. By establishing the analytical magneto-motive force (MMF)-permeance model, the DC winding induced voltage per electrical cycle under open-circuit condition, armature reaction condition and on-load condition are deduced. Analytical analysis shows that the MMF function, stator and rotor permeance function are critical factors that influence the harmonic order of the DC winding induced voltage. The analysis results are compared with those predicted by the finite element analysis (FEA). Both non-linear steel and linear steel conditions are accounted in the FEA analysis, and the results show that the analytical deduction result agrees well with the FEA analysis result.
