What is Blocked Rotor Test of Induction Motor?
Blocked Rotor Test Definition
The blocked rotor test of an induction motor is defined as a test to find the leakage impedance and other performance parameters.
Purpose of Blocked Rotor Test
It determines torque, motor characteristics, and short-circuit current at normal voltage.
Testing Procedure
During the test, the rotor is blocked, and low voltage is applied to the stator to measure voltage, power, and current.
Effect on Impedance
Rotor position, frequency, and magnetic dispersion can impact the measured leakage impedance.
Short Circuit Current Calculation
The test helps calculate short circuit current for the normal supply voltage by measuring specific parameters.
