2.2 TESTING OF STATOR.

Using Multimeter, check the resistance between

the phases of the stator winding. The resistance

should be 0.040 ± 10% ohms per phase.

2.3 TESTING OF ROTOR:

Measure the resistance of the rotor winding at the

slip ring with multimeter. Resistance should be 2.1

± 10% Ohms at 20 deg c or 3 ± 10% ohms at

room temperature.

3.0 ASSEMBLY

3.1 Bearing Pressing in DEF:

If the bearing in the drive end shield (

DEF

) has

been discarded. Press in a new bearing using an

Arbor press. Assemble the bearing holding cover

late on the drive end flange using four counter

sunk screws such that the projection of the cover

plate is towards the rotor.

3.2 Rotor assembly in to the DEF:

Place the rotor as shown; put the drive end shield

on the rotor shaft as shown, press in the drive end

flange by a Spacer ring using an Arbor.

3.3 Slip ring assembly:

Press the fitting ring into the slip ring end shield,

ensuring the opening of the fitting ring towards the

mounting position of the voltage regulator.
