This paper presents a parameter estimation method for a permanent magnet synchronous machine (PMSM) based on the instantaneous input impedance, which is defined as a function of the instantaneous voltage and current space vectors fixed to the rotor reference frame. The parameters are calculated solving the nonlinear optimization problem to minimize the difference between the estimated and measured input voltages. This problem was solved using Interior-Points, and Genetic Algorithm (GA) to compare the computing time required in each case. The parameter estimation method was evaluated using data obtained from a co-simulation between ANSYS RMxprt-Simplorer® and MATLAB-SIMULINK® in a PMSM drive application using conventional Field Oriented Control (FOC) approach. The results prove the method capability to estimate the direct and quadrature self-inductances, and the magnet flux. Also, the stator a reasonable value of the stator resistance can be estimated. Finally, the paper presents an additional simulation of the PMSM using the estimated parameters, and the outcomes have a good correspondence with those obtained from the co-simulation.
