Therefore, the motor stator and rotor resistances are R

r
= 24 mΩ according to equa-
tions (9.5) and (9.7) and the leakage inductances according to equation (9.6) are:

It is noted that the synchronous frequency in locked rotor test is different to the synchro-
nous frequency in no-load test. Finally, the L
