  7. Abstract:
  8. One of the main challenges of resolver as a position sensor is using at high speeds. Because in a situation where the speed of moving part is close to the frequency of the resolver excitation voltage, the speed-dependent part in the resolver output signals will be significant and cannot be ignored. In this project, the aim is to provide a method to solve the problem of using a variable reluctance linear resolver with a sinusoidal cross section in a wide speed range. This method is based on the hybrid use of AC and DC excitation in such a way that AC excitation is used at low speeds and DC excitation at high speeds. Considering that determining the threshold speed requires a large number of simulations in a wide speed range for AC and DC excitation. The use of the finite element method is not appropriate in this stage, despite the high accuracy, and the use of analytical methods is needed. Therefore, in this research, an analytical model based on the field reconstruction method is presented to predict the performance of this resolver, which has acceptable accuracy and solution time. Then, by using the proposed model, the resolver performance is predicted in a wide speed range and the threshold speed is selected. Finally, a prototype of the presented structure is built and tested. The measured experimental results confirm the accuracy and effectiveness of the proposed hybrid resolver
