“…In addition, the eccentricity issue during installation and processing is also one of the factors affecting the measurement accuracy of resolvers [17]. In [18], the measurement error is reduced and the error caused by the rotor eccentricity is suppressed by building an analytical current model. In [19], the Siamese network was used to detect the static eccentricity voltage of each tooth of the resolver, and the eccentricity position was extracted by converting it into a rotor angle.…”

In this paper, a type of co-excitation axial reluctance resolver (CARR) in different winding modes is taken as the simulation model. Detailed explanations have been provided on its stator, rotor, and windings. Simultaneously, an introduction was made to the distribution of two types of signal winding modes. The influence of three kinds of eccentricity on the output characteristics of this CARR during installation and fabrication is also studied. According to two kinds of signal winding modes, the variation law of waveform and amplitude of output potential is analyzed under the conditions of stator radial eccentric distance in different eccentric directions, rotor radial eccentric distance in different eccentric directions and rotor axial offset, and the influence of three factors on total harmonic distortion (THD) is analyzed further. Under the conditions of different eccentricities and offset, a prototype of 15 pair pole CARRs in the mode of sinusoidal windings is tested. The function errors of the signal windings under conditions of radial eccentricity of the stator, radial eccentricity of the rotor and axial offset of the rotor were measured separately. The variation rule of error was compared between measurement and simulation. The correctness of the finite element simulation results under three different eccentricity conditions was verified. The verification results provide theoretical support for further optimization of structural parameters and the installation of the stator and rotor, which can improve measurement accuracy.
