Abstract
Because of temperature independence, high resolution and noiseless outputs,
brushless resolvers are widely used in high precision control systems. In this paper, at first
dynamic performance characteristics of brushless resolver, considering parameters
identification are presented. Then a mathematical model based on d-q axis theory is given.
This model can be used for studying the dynamic behavior of the resolver and steady state
model is obtained by using dynamic model. The main object of this paper is to present an
approach to identify electrical and mechanical parameters of a brushless resolver based on
DC charge excitation and weight, pulley and belt method, respectively. Finally, the model
of resolver based on the obtained parameters is simulated. Experimental results approve the
validity of proposed method.

Abstract
A mathematical model based on d-q axis theory and dynamic performance
characteristic of brushless resolvers is discussed in this paper. The impact of rotor
eccentricity on the accuracy of position in precise applications is investigated. In particular,
the model takes the stator currents of brushless resolver into account. The proposed model
is used to compute the dynamic and steady state equivalent circuit of resolvers. Finally,
simulation results are presented. The validity and usefulness of the proposed method are
thoroughly verified with experiments.
