“…The primary coil of RT is located on the stator and fed by the excitation voltage and the induced voltage in the secondary coil of the RT that is located on the rotor of the resolver is used for feeding the rotor winding [3]. The difficulties in using RT and the requirements of using lowprice resolvers pushed the researchers into proposing a new generation of resolvers with no-winding on the rotor [4,[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Most of these resolvers work based on sinusoidal variation of airgap permeance that can be attained by sinusoidal variation of airgap length [6][7][8][9][10][11][12][13] or sinusoidal variation of coupling area [18][19][20].…”

Most of the resolvers used in high precision servomechanism are two-pole, wound-rotor ones. The configuration of their stator winding is based on variable-turn, on-tooth method. However, there is different opportunity for their rotor: using distributed winding or on-tooth one. Furthermore, based on the operating principle of the resolver its rotor needs a single phase winding. While, in many practical cases a two-phase winding that one of them is short-circuited (damper winding) is employed for rotor. In this study, the effect of different configurations for rotor winding on the resolver performance in terms of the average of absolute position error, maximum position error, and total harmonic distortion of induced voltages envelopes is investigated. Then, the effect of damper winding on the performance of the resolver under static-, dynamic-, and mixed-eccentricities are studied. In this study, all simulations are performed using three-dimensional time stepping finite-element method and finally, the experimental tests on the studied sensor using a precision test setup are employed to approve the simulation results.
