In the case of testing for the characteristics of induction motor, there are two methods, namely, Ko and Otsu kind circle diagrams. But, these methods are very difficult to test a special type machine, such as deep slot or double cage rotor. Generally, an induction motor is designed to the maximum power factor of input coincides with the neighbourhood of the rated output of machine, then, we think that if we will use this point to add to no load and locked points in the Ko or Otsu kind circle diagram and draw it, the result of testing is correct and easy. From this point of view, we tested the several types of machine such as single squirrel cage, double cage and deep slot rotor, and compared the characteristics of these machines. A maximum power factor is changed with the supplied voltage, so that, it must be used the value at the rated voltage. By the result of experiments, it is cleared that the percentage error by the three point method is approximately equal to the other methods for the light load, but for above the 75% load, is better than the other two methods.
