“…Although the proposed resolver can detect position in rotational, linear and helical motion, high position error and high volume of the proposed resolver make it inappropriate choice for employing in control systems. To increase the accuracy and reduce the volume of the sensor, another configuration has been proposed in [13]. However, its further accuracy improvement needs the iterative optimization process that is not compatible with finite element simulations.…”

“…However, the subject of all the mentioned literature is 1-DOF linear or rotational motion resolvers. The analytical model based on WFM and MEC methods for the 2-DOF resolver of [13] is presented in [24,25], respectively. However, those models ignore the longitudinal end effect while referring to the study of [22]; the performance of tubular resolvers is sharply deteriorated due to end effects.…”

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.

“…In both investigations, the slotted core is considered for a linear resolver, and the subdomain method capability is proved for the modeling purpose. The two Degree of Freedom (2DoF) resolver is another new type of resolver that can measure the rotary and linear position [16], [17], where a MEC and the Finite Element Method (FEM) are used for analysis, respectively. FEM is used many times for this aim, but has two significant drawbacks: long processing simulation time and intensive processing.…”

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.
