5. Checking of motor/failure analysis

As the reliability of submersible motors is very important, used motors must be checked and then dismantled. By doing this the cause of the fault can be identified, in case the motor has been damaged. Always take care to thoroughly inspect, analyse and document each individual components, both before and during dismantling. Check the following points before dismantling :

• Check the motor for damage, fractures or the like.

• Check that the motor is filled with liquid and has no leaks at the diaphragm or shaft seal.

• Check that the height from the shaft end to the contact face of thread holes is 72.8 ± 0.2mm.

• Check that axial clearance is minimum 1 mm.

• Check that the motor shaft spins freely.

• Check that the plug pins for the cable connection are not defective or burnt.

• Check that the winding resistance is as stated in electrical data.

• Check that the motor insulation resistance complies with local regulations. In case of motor repair, however, the resistance must be at least 1 MΩ.

• Submerge the motor cable and the submersible drop cable in water and check that there is no leakage in the cables.

• If the motor is connected to a control unit, type MP204, check the signal from the temperature transmitter of the motor.

• Ohm the motor with the cable mounted on.

• Meg the motor with the cable mounted on.

• Ohm the motor with no cable, directly on the terminals.

• Meg the motor with no cable, directly on the terminals.

1. Checking the motor and cable

1. Supply voltage

2. Current consumption

Items 3 and 4: Measurement is not necessary when the supply voltage and current consumption are normal.

3. Winding resistance

4. Insulation resistance

Measure the voltage between the phases by means of a voltmeter. Measure on the terminals where the submersible drop cable is connected.

TM00 1371 5092

Measure the current of each phase while the pump is operating at a constant discharge pressure (if possible, at the capacity where the motor is most heavily loaded). For maximum operating current, see nameplate.

TM00 1372 5092

Disconnect the submersible drop cable at the motor-protective circuit breaker. Measure the winding resistance between the conductors of the submersible drop cable. See section

2. Winding resistances. Note: Include the resistance of the submersible drop cable. See section 2.3 Resistance values for cables.

TM00 1373 5092

Disconnect the submersible drop cable at the motor-protective circuit breaker. Measure the insulation resistance from each phase to earth (frame). Make sure that the earth connection is made carefully.

When the motor is loaded, the voltage should be within the required voltage quality for Grundfos MS submersible motors which,measured at the motor terminals,is - 10 %/+ 6 % of the rated voltage for continuous operation (including variation in the supply voltage and losses in cables). Check also that there is voltage symmetry in the power supply lines, i.e. the same difference of voltage between the individual phases. Large variations in voltage may cause the motor to burn. Large variations in voltage indicate poor power supply, and the motor must be stopped until the defect has been remedied.

On three-phase motors, the difference between the current in the phase with the highest current consumption and the current in the phase with the lowest current consumption must not exceed 5 %. If so, or if the current exceeds the maximum operating current, there are the following possible faults:

• The contacts of the motor-protective circuit breaker are burnt. – Replace the contacts or the control box for

single-phase operation.

• Poor connection of conductors, possibly in the cable joint. – See item 3.

• Too high or too low supply voltage. – See item 1.

• The motor windings are short-circuited or partly disjointed. – See item 3.

• Damaged pump is causing the motor to be overloaded. – Pull out the pump for overhaul.

• The resistance value of the motor windings deviates too much (three-phase). – Move the phases in phase order to a more uniform

load. If this does not help, see item 3.

For three-phase motors, the difference between the highest and lowest winding resistance must not exceed 10 %. If the deviation is higher, pull out the motor. Measure motor, motor cable and submersible drop cable separately, and repair/replace defective parts.

If the insulation resistance deviates from the values in section 1.1 Insulation resistance, the motor should be pulled out for motor or cable repair. Local regulations may stipulate other values of insulation resistance.

TM00 1374 5092

Page 17

1.1 Insulation resistance

Note

The insulation resistance must be measured in accordance with local regulations.

The table shows suggested values of insulation resistance and the test voltage in relation to the rated voltage of the motor.

Rated voltage: ≤ 500 [V] > 500 [V]

Condition of motor and cable [MΩ][MΩ]

New motor (without submersible drop cable)  200  200 Used motor which can be reinstalled in well  10  10 New motor in well  20  20 Motor in good condition in well  0.5  1 Damaged insulation < 0.5 < 1

If the rated motor voltage is ≤ 500 V, the insulation resistance must be measured at a test voltage of 500 VDC.

If the rated motor voltage is > 500 V, the insulation resistance must be measured at a test voltage of 1000 VDC.
