TASK 5: Test for short circuit in stator
1 Check the insulation of the stator windings by connecting a 220 V AC mains with a 220 Volt. 15 W test lamp in
series between the stator laminators and each one of the three stator lead one by one. The lamp should not
glow. It the test lamp glows then the stator winding is defective, renew the same (Fig.1).

TASK 6: Test for short circuit in rotor
1 Check the rotor winding insulation by connecting to a220 V AC mains with a 220 V 15 watt test lamp in circuit
between either of the slip-rings and the rotor body. The lamp should not glow. If the lamp glows then the rotor
winding is defective; rotor assembly need renewal (Fig 1).
