“…(2) Limitations to the coordination of poles and slots: The pole pairs of the resolver and the tested motor need to be designed in conjunction, which cannot fully follow the design concept of the resolver. Moreover, the given space size further limits the stator design and distribution of the winding turns [23][24][25].…”

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.

Wound-Rotor resolvers are the oldest and the most widely used resolvers. They are twophase synchronous generators with high frequency AC excitation. Rotary Transformers (RTs) are used to supply the rotating excitation winding of the resolver. Although RTs offer the benefits of contactless power transmission, harmonic contents of the secondary voltage, phase shift error between the primary and the secondary voltages, and high leakage flux are the main challenges in their usage along with resolvers. Therefore, in this paper, different configurations are examined for RT's ferromagnetic core to overcome the mentioned problems. All the simulations are done using 3-D time variant finite element method (TVFEM) and the best configuration is chosen for experimental prototyping and measurements. Close agreement between the simulation and the experimental test results approves the performed analysis.

“…Various structures are presented for the WR and VR resolvers [4], [5], [8], [9], and also it is investigated that WR resolvers have higher accuracies compared to the VR type. Although accuracy issues can make the WR resolvers superior to VRs, difficulties in the winding process and higher price structures are the main drawbacks of these resolvers in long-distance applications [10].…”

A Novel Method for Accuracy Improvement of Variable Reluctance Linear Resolvers

1Abstract-A novel technique for accuracy improvement of the Variable Reluctance Linear resolvers (VR-L resolvers) is investigated in this paper. A well-known structure and calculation correcting factor are applied to propose a VR-L resolvers model with higher accuracy. A periodic Finite Element Analysis (FEA) is employed with a shorter processing time. The modeling is also performed for conventional and proposed improved structures by the mentioned FEA, where the extra teeth suppress the end effect in the model. The main reasons for the position error in linear actuators/sensors are the windings' end effect and nonequal magnetic circuit. Two additional compensator teeth/slots with different heights are considered at both entrance and front parts of the mover, which introduces an improved structure. Furthermore, a new correction factor is employed to amend the demodulation process resulting in better performance. Compared to the conventional type, the proposed resolver is evaluated in healthy and faulty cases with asymmetric air-gap conditions. It is shown that the position error is significantly reduced in the improved structure. Finally, the effectiveness of the proposed design is proved by experimental results.
