Using a planar sensor instead of two linear ones decreases the complexity, and cost of the employed drive. Therefore, in this paper a new slotless configuration is proposed for the planar resolver, that simplifies the manufacturing of the sensor. Then, the optimal combination of the stator/mover number of coils is determined based on the proposed analytical model. Finally, to reduce the number of integrated parts of the proposed resolver, a new configuration with skewed coils is proposed. The success of the developed model and the presented configuration is validated using three-dimensional finite element analysis.</span></span> 2-DOF Resolver, Planar Resolver, Wound Mover Resolver, Winding Function Method, Slotless Resolver. 65 74 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-263-9&slc_lang=en&sid=1 Fateme Zare f.zare.1373@gmail.com 1800319475328460014081 1800319475328460014081 No Department of Electrical and Computer Engineering, Isfahan University of Technology, Isfahan Farid Tootoonchian tootoonchian@iust.ac.ir 1800319475328460014082 1800319475328460014082 Yes Iran University of Science and Technology
