MEASUREMENT OF ROTOR LEAKAGE REACTANCE OF INDUCTION MOTOR

Induction motor is the most common drive. The performance of the motor can be predicated by use of equivalent circuit. All the parameters in the equivalent circuit can be determined and measured. The leakage reactance of stator and rotor are measured as sum of stator reactance X1 and the referred reactance of rotor as X2′. The separation is done by thumb rule. This paper attempts to separate these two parameters experimentally
