“…In [3], DC offset error, scale error, and phase error are classified and a compensation method is proposed for accuracy improvement. In most resolvers, the winding arrangement is an important factor for the resolver performance and its influence on accuracies are analyzed in [5], [6]. Moreover, the rotor shape is another important property that is studied in [7], [8].…”

“…These factors have the same influences on both rotary and linear resolvers. However, the end-effect and the windings' nonequal magnetic circuit cause some differences between the linear resolver's performance and rotary types [6]. Although there are some presented researches in the resolvers analysis, few works are presented for the linear resolvers compared to the rotary type.…”

“…The linear resolvers are categorized into two types. The first type has a Variable Reluctance (VR) structure [6], [9], where the windings are located on the mover, and the stator is designed based on the sinusoidal air-gap permeances. The second type is designed based on the slots/teeth stator structure, where the windings are placed on both mover and stator [10]- [13].…”

“…Since the end-effect has considerable influence on the linear resolvers, its modeling is an important issue that should be considered. 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.…”

“…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.

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.

A novel DC-Excited Flux-Switching Linear Motor (DC-FSLM) is investigated in this paper, where a simple secondary is used as the machine stator. The phases and excitation windings are placed on the primary, which contributes to a low-cost and simple structure linear motor with acceptable dynamic performance. The motor operation under dynamic load is analysed by a parametric Magnetic Equivalent Circuit (MEC), and the core saturation is modelled by the non-linear reluctance of the flux tubes. Moreover, the endeffect is considered by virtual zones at both entrance and exit ends of the primary. In the considered MEC, the model accuracy can be selected as desired as well as different DC-FSLMs with various properties can be modelled. Finally, the machine capabilities and performance characteristics are discussed by simulation results, and validation is performed by the Finite Element Method (FEM).This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
