To change the phenomenon of "Being an armchair strategist" in current research for resolver, a simulation system of virtual resolvers is researched adopting virtualization. The fundamental principle of resolver and the developing strategy of simulation software are expatiated. Some common problems in the system developed are solved, including the way of real-time updating image, the rotor-rotating method, and the approach of adjusting parameters. In addition, examples of phase discrimination resolvers and amplitude discrimination resolvers are provided separately. This paper provides a worthy auxiliary instrument for resolvers to be researched.
