Popis: 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.
