A 24 kW, 415 V, 50 Hz star-connected 6-pole, squirrel cage induction motor is subjected to the standard no-load test and the locked rotor test. A 24 kW, 415 V, 50 Hz star-connected 6-pole squirrel-cage asynchronous motor was tested with standard no-load and lock rotor tests. The stator resistance and the 'stator-referred to 'rotorl resistance are known to be R1 = 0.7, R = 0.5, respectively. The stator resistance and the 'stator-referred' rotorl resistance are known to be. The known stator resistance and "stator reference" rotor resistance are R1 = 0.7 and R = 0.5, respectively. The standard no-load test is carried out at 415 V. Standard no-load tests are performed at 415v. The (total three phase) real powerinput is measured as 860 W and the current is measured as 1.2A. The actual input (total three-phase) power is 860 W and the current is 1.2 A. Rotational losses at synchronous speed are known to be 490 W. The known rotational loss at synchronous speed is 490 watts. The standard locked rotor test is performed by increasing the motor voltage to 115 V (line-to-line) at which the line current reaches 33 A. The standard locking rotor test is performed by increasing
