Abstract

This paper presents the precise measurement of the stator inductance as well as the stator resistance, using an inverter. Precise measurement results are created, although the actual output voltage of the inverter is not known exactly. This paper analyzes the different effects of an output power stage, and how they degrade the quality of the output voltage. This knowledge is used to cancel out this output voltage error in enabling a precise measurement of the machine parameters. This allows an easy auto commissioning of the current controller and furthermore an auto commissioning of an optimal torque control. The presented methods are verified with extensive measurement results.
