A Frequency Response Method for Determining the Parameters of High-Performance DC Motors

This paper introduces a technique for measuring the parameters of high-performance dc motors. A second-order motor model, under certain conditions, is shown to be equivalent to a series resonant electrical circuit. Frequency response measurements of the motor, when treated as an electrical impedance, form the basis of a measurement technique which has certain practical advantages. Results are compared to measurements made using conventional methods.
