It is how to generate the heat loss in the motor without actual loading that is important in these methods, and the difference between various methods lies here. Our method is easy and simple, and is as follows. The motor is running with no load by the impressed unbalanced three phase voltage, and the input is adjusted so as to be equal to the loss when the motor is running normally with the rated load. The means by which we impress the unbalanced three phase voltage to the three phase induction motor is the single phase running of three phase induction motor with inserted resistance, etc. In our method the current of three phase is not always equal, and therefore we adopt the mean value of temperature rise of three phases in determination of the temperature rise of stator winding., Article, 信州大學紀要 (2): 119-125(1952)}, pages = {119--125}, title = {三相籠形誘導電動機の簡易温度上昇試験法}, volume = {2}, year = {1952} }
