Methods for determining the parameters and characteristics of PMSM

Determination of parameters is required for modeling and performance analysis of electrical machines. As permanent magnet synchronous machines (PMSMs) do not have a plethora of literature, standards and patents for parameter determination, this paper presents a comprehensive study of the available methods in literature for parameter determination along with novel methods of d- and q-axis inductance measurement proposed by the authors. Besides, the presented methods for measurement and calculation of armature resistance, flux linkage constant, leakage inductance, and d- and q-axis inductances are applied to a laboratory PMSM and evaluation of the proposed methods based on their complexity and accuracy is performed according to the experimental results.
