It is possible to estimate the starting performance of a squirrel-cage induction motor by the actual loading method, circle diagram method, equivalent circle method, and so on.<br>However, since these methods employ a commercial three-phase power supply, the testing equipment used becomes large-scaled with the increase in capacity of the tested equipment.<br>The set tester used at the testing factory can be sized down if the starting performance can be estimated by standstill tests using small-capacity devices.<br>In this paper we propose a new method which can estimate the starting performance by standstill tests using a small-capacity D. C. power supply. In this method, a D. C. current is first made to flow through the armature winding (two terminals with the third one open) of an induction motor.<br>Then the current decay, caused by short-circuiting between the two phases, is recorded.<br>The operational impedance on the induction motor per phase is determined by Fourier transformation of the current decay.<br>The starting performance is obtained using the two-reaction theory.<br>This paper shows that this method is clearly useful as an estimation method for the startig performance.
