Variable reluctance (VR) resolvers have some distinguish features over wounded rotor resolvers that make them suitable for industrial applications. Among different types of VR resolvers, sinusoidal-rotor resolvers are preferred due to simple structure and high performance under eccentricities. However, their accuracy is affected by inevitable run-out error. As they work based on sinusoidal variation of coupling area between stator and rotor and under run-out error the coupling area is impaired. Hence, in this study, a new disk shape configuration is proposed for sinusoidal-rotor resolver that is robust against run-out error. Geometrical dimensions are calculated based on optimisations to achieve more accuracy. Three-dimensional time-stepping finite-element method is used to show the preference of the proposed resolver. Finally, prototypes of both conventional and proposed sensors are built and tested. Experimental results verify the success of the proposed structure.

“…VR resolvers work based on sinusoidal variation of air-gap reluctance. In this regard, two types of VR resolvers emerge: sinusoidal air-gap length (SAGL) resolvers [3] - [9] and sinusoidal area (SA) resolvers [10]- [14]. The commercial VR resolvers are SAGL types.…”

“…To improve the resiliency of the SAGL resolver under eccentricities, disk type resolvers are proposed [3], [9]. Furthermore, SA resolvers are also proposed to overcome the disadvantages of the SAGL resolvers [10]. However, they have their own challenges that are huge dimensions, and inappropriate performance under run-out fault.…”

Wound-rotor (WR) resolvers are the most commercially used resolvers in industrial applications. In this paper, the effect of different winding arrangements on the accuracy of WR resolvers is discussed. Three windings are proposed for the stator of the resolver that are involved on-tooth overlapping winding, distributed lap winding and distributed concentric winding. Those windings are also applied to the rotor. All the rotor windings are assumed to be single phase and two-phase. Therefore, the effect of damper winding is also studied in the paper. The analysis is done using time stepping finite element method and the most accurate resolver is built and tested. Close agreement between the experimental measurements and the finite element results confirms the obtained results.

Most of the resolvers used in high precision servomechanism are two-pole, wound-rotor ones. The configuration of their stator winding is based on variable-turn, on-tooth method. However, there is different opportunity for their rotor: using distributed winding or on-tooth one. Furthermore, based on the operating principle of the resolver its rotor needs a single phase winding. While, in many practical cases a two-phase winding that one of them is short-circuited (damper winding) is employed for rotor. In this study, the effect of different configurations for rotor winding on the resolver performance in terms of the average of absolute position error, maximum position error, and total harmonic distortion of induced voltages envelopes is investigated. Then, the effect of damper winding on the performance of the resolver under static-, dynamic-, and mixed-eccentricities are studied. In this study, all simulations are performed using three-dimensional time stepping finite-element method and finally, the experimental tests on the studied sensor using a precision test setup are employed to approve the simulation results.
