Experimental Validation with Field Circuit by Changing Start Voltage of Salient Pole Synchronous Motor

Abstract

This paper reports on the experimental validation characteristics of a salient pole synchronous motor with the starting field circuit in contact. The starting characteristics were experimentally evaluated at voltages of 100%, 75%, and 50% using a 1.5kVA salient pole synchronous motor. The signal for pulling into step was applied to the field circuit by using the control module, for all test conditions. The results confirmed the proper pulling into step at 100% of voltage, and the results of the tests at 50% and 75% of voltage revealed that the pulling into step under these conditions becomes stable at the suitable slip condition.
