Abstract: The VR type Resolver is an angle sensor for the motor of electric vehicles and hybrid electric vehicles. The static angle accuracy of the Resolver affects the dynamic error during rotation of the motor. Therefore, for the purpose of reducing the static error of the Resolver, the cause of error was investigated by means of experiment and FEM analysis, especially regarding the effect of leakage flux distribution around the coils. As a result, it became evident that the flux distribution in stator slots is not equal, thus uniform winding and balance between 2-phase output coils are needed.
