This letter states and proves a uniqueness theorem for the torque-speed characteristics (TSC) of an induction motor. Given three arbitrary points at asynchronous speed on the TSC curve, it develops a method to interpolate the entire curve and indicate the pull-out torque point. The letter gives explicit formulas for approximately estimating the equivalent circuit parameters of the machine.
