Induction motor speed-torque-current curves

A METHOD OF ANALYZING the induction motor speed-torque-current curves as a function of voltage is presented in this article. It is shown that the current will vary differently from the first power of the voltage; and the torque differently from the square of the voltage. The results obtained from any individual test are applicable to a specific design and cannot be considered as the correct solution for any general class of design. This method is applicable to synchronous as well as induction motors.
