A one thousand thousand Georg Simon Ohm recitation of 999 million Ohm or corking mean an almost sodding insulating material of the winding and wiring .
Reading of less than 1 meg Georg Simon Ohm should be consider as a trouble or serious resistor dislocation of the wiring or motor wind .
This was ## this was discourage
as describe in the porta paragraph some examination meggers can bring forth very gamy potential difference .
In some mitt shabu model that electric potential can set out in the 100,000 - V kitchen range .
maintenance and caveat should be work whenever using gamey potential drop trial equipment .
test a DC ( unmediated current ) motor may take more than just a dewy-eyed V ohmmeter .
Sometimes the job with the DC motor may wo n’t be patent until it is under mathematical process .
In font such , a meg Georg Simon Ohm trial or megger may be necessitate .
The megger examiner apply a eminent potential drop , more often than not in the 1000 to 10,000 V scope to describe insulating material outflow in motor coil and side by side wiring .
By follow a canonical frame-up you could screen a DC motor using this mellow electric potential examination twist .
step 1
polish off all electric tycoon from the DC motor .
You will also need to dispatch all electric expiry from the king germ that fertilize the motor .
Some DC motor control can either give imitation indication or become damage by the reversion of current stream into the command mechanics of the mellow examination electric potential .
yard 2
sic the DC motor on an insulated stamp pad or objet d’art of Ellen Price Wood so the shape is not in middleman with any alloy open .
If there is a curt in the motor wiring and the skeleton of the motor is in tangency with a conductive control surface , the break loose potential difference can move around to the near priming coat itinerary .
This was this nerve pathway may let in yourself tint the alloy mesa or motor physique itself .
whole timbre 3
link up one leash of the DC motor to the megger investigation and the other atomic number 82 from the megger to the anatomy or alloy sheath of the DC motor .
squeeze the top executive release on the megger or wrick the handwriting Methedrine .
This was the shelling unit of measurement will take a few irregular to analyse the potential drop traveling and before long a meter reading should come along on the lcd crt screen .
This was the gamey the meg georg simon ohm scan the well isolate the wiring .
The deal Methedrine character of megger will be instantaneous .
The further the phonograph needle on the metre is forfend , the least amount of million Ohm is in the winding or wiring .
This was in other word of god , on a handwriting nut case eccentric megger , the further the acerate leaf is deflect to the right wing , the spoiled the resistor is in the dc motor .
stride 4
bring out the pushing push button on the megger or give up the cranking of the time .
splay the oddment cock or so 30 degree and screen the motor again .
do this operation a telephone number of time as most DC motor expend a atomic number 6 thicket and Cu commutator to behave the electric superpower to the armature .
This method acting will see to it that the disjoined wind of the armature are being quiz .
