Reluctance resolver has the advantages of high reliability,durable and strong anti-interference,which is widely used in the motor control system of electric motorcycle.In this paper,based on the analysis of the structure and working principle of the reluctance resolver,combined with the application requirements of the electric motorcycle,a l4/4 stage structure of the resolver is designed.Firstly,the stator and rotor structure parameters and winding distribution of the reluctance resolver are calculated.Then through the simulate calculation by Ansoft,the effectiveness of the design scheme is preliminarily verified.Finally,the experimental prototype is manufactured and the design scheme is further verified through experiments.The results show that the output sine and cosine waveforms of the newly designed reluctance resolver meet the requirements and can accurately measure the rotor position information.
