Stator med

urpressningsverktyg

If using a 500 V megger the insulation resistance shall exceed
0.5 megaohm. This applies to phase-to-phase readings as well
as between each phase to ground. If the insulation resistance is
less than 0.5 megaohm, the stator should be dried in an oven.
Also check the resistance in the stator. Disconnect the stator
cables from the terminal block and measure directly at the stator
cables.

Note! Notice How the Cables are Connected on the
Terminal Block.

Also check the circuit with the three built-in thermal overload
switches using a buzzer or a bell. If the circuit is open, probably
one of the overload switches is defective.

If the stator still cannot be used, it has to be replaced. Disconnect
the stator from the outgoing cables and disassemble it. Order an
exchange stator unit from the nearest Pumpex Service Center.

Disassembling the Stator

Disassemble the terminal housing as instructed above.

Remove the six screws that hold the stator casing. Use three
M16 screws and thread them into the three threaded holes at the
lower flange so that the stator unit is lifted up from the oil housing.

Gently, with a hoist (recommend Eyebolt M16),lift the stator
casing from the rotor/shaft. Note! Disconnect the cable from the
moisture sensor in the oil housing before the stator is totally lifted
up. Put the stator unit on a distance tube.

Place the pressure tool on the stator and pull the stator out of the
casing (Fig. 6).

Note! Record the Distance from the lower edge of the
Stator Housing to the Edge of the Stator Before the
Stator is Pressed Out.
