Even though the subdomain model can accurately predict magnetic flux density in the air gap considering the slotting effect and also longitudinal end effect, the computational time is very long, and the 3D effects cannot be included [16].…”

In this paper, Field-Reconstruction Method (FRM) is proposed for predicting the performance of different types of rotational resolvers, including Wound-Rotor (WR) and Variable Reluctance (VR) ones. The main features of the developed method are comparable accuracy with that of the Finite Element Method (FEM) as well as much less computational burden. The deviation of the developed model in the prediction of position error of WR and VR resolvers is less than 3%. While its simulation time is between 30 and 150 times faster than FEM, depending on the resolver type. Accordingly, the proposed model can be used for the design and optimization of different resolvers. Experimental tests on the prototype WR resolver verify the success of the analysis in the modeling of the resolvers.

“…This effect is considered in [6], [13], where a Magnetic Equivalent Circuit (MEC) is used in [6], and two additional air zones are defined in both the entrance and front parts of the mover. In [13], [15], the subdomain method is used for modeling, which considers the end-effect, but the core nonlinearity effect is omitted. In both investigations, a slotted core linear resolver is employed, and the capabilities of the subdomain method for modeling purposes are proved.…”

“…By noticing the performed researches, there are four conventional methods for the resolvers analysis. Magnetic Equivalent Circuit (MEC) [5], [6], [16], [19], [20], Winding Function Approach (WFA) [21], [22], subdomain method [13], [15], and Finite Element Method (FEM) [18] are used by researchers for designing, optimizing, or analyzing the resolver models. Although FEM is a powerful method, the iterative simulations make the process less suitable compared to a flexible MEC method.…”

A novel linear resolver is proposed in this paper. The excitation and signals windings are placed on the mover, and the stator structure is designed by a certain number of teeth/slots per the mover length. Therefore, the proposed structure is more simple compared to other resolver types and causes a low price structure. A flexible Magnetic Equivalent Circuit (MEC) is used for analysis thanks to its capability, introducing various structures. The resolver performance under healthy and faulty cases is evaluated, where the position error under asymmetry air-gap fault is obtained. Performed analysis shows that the proposed resolver has less than 100 µm position error. Hence it can be a proper alternative as an accurate position sensor. The simple structure and high-accurate position estimation are the advantages of the proposed resolver compared to other types. Finally, the effectiveness of the proposed resolver is validated by experimental results.

“…In addition to rotation resolvers, analytical models are employed to study the performance of linear flat ones. For example, [19] employed the subdomain method to study the performance of WR linear resolver. In [20,21], WFM and MEC models are employed to study the performance of VR and variable air-gap length linear resolvers.…”

Using multiple position sensors in the control system of Two-Degrees of Freedom (2-DOF) motors causes it more complicated than that of conventional 1-DOF ones. However, employing a 2-DOF position sensor in comparison with two independent sensors, reduces the complexity, mass and volume of the system. The common 2-DOF sensors are able to determine the position in linear, rotational, and helical motion. Yet, they suffer from accuracy reduction due to the longitudinal end effect. Therefore, analytical modelling and the relevant compensation methods are discussed. The accuracy of the model is approved by comparing its results with those of 3D time transient finite element method. Afterwards, the model is used for compensating the end effects. Finally, the optimised 2-DOF resolver is prototyped and tested. The result of experimental test shows the proposed resolver's success.
