A step voltage method for determination of an induction motor rotor time constant in a cold state

The method for determination of an initial rotor time constant of a cage induction motor is presented. It consists of applying the step form voltage and measuring the responding current. After some simplifications the current response term becomes easy to analyze. At least two measuring points are n...

Description
Summary:The method for determination of an initial rotor time constant of a cage induction motor is presented. It consists of applying the step form voltage and measuring the responding current. After some simplifications the current response term becomes easy to analyze. At least two measuring points are necessary for determination of both stator and rotor time constants.< >
