Characteristic Test Method of Linear Synchronous Generator Using Single-phase AC-voltage with Various Frequency

摘要

Armature resistance and electromotive force can be identified by conventional DC test and no load test. However, such conventional test method can not be used for measurement of d-axis and q-axis inductances. Authors propose to apply single-phase small AC-voltage as measurement voltage source into three phase winding connected as the proposed circuit to identify the two inductances by fixing mover to certain position. The proposed method is explained in detail and verified by numerical and experimental case studies.
