Hello Folks
We let the smoke out of a 230V Drive cooling fan motor, one leg is neutral the other 230VAC for a Heidelberg printing press . Sent it out for rewinding and it came back looking really nice however when I energized it, no joy! It just hummed and I felt resistance while nudging it in...
Our contactor supplies 380V off of two legs of three phase system to the primary of a
high voltage transformer. It is for Ultra violet light system on printing press. Previous
to me getting on seen this thing caught fire destroying several contactors and wiring in
cabinet with two other guys...
Good morning
We are experiencing catastrophic failure of drives and controller and have been unsuccessful locating the Gremlin which necessitated a Data logger, the event shown here took out two capacitors
on one of the DC drives Monday morning.
The logger is connected at machine on 400V...
Our drive system has blown 1 controller unit, 1 drive and several fuses, we think the issue is corrected so I am monitoring behavior to be sure.
I used a Techtronix 10Mv/Amp clamp with Fluke 8845A for these readings and would appreciate your thoughts/interpretation of them. The current and...
Hello Gentleman
Currently servicing an AMK az-40 drive system without current reading display. I would like to get an accurate amp reading to each of the four motors it supplies.
Using a Fluke i1010 current clamp is useless, it's Bandwidth rating is 10 KHz. The readings I'm getting are totaly...
Hi Folks
Any alternatives to this unit, they are obsolete now and very expensive ($4000.00). My armature volts is 240V and 89A. The problem with these I think is the small copper square ring around the laminated plates, this ring cracks or opens and I'm thinking it is the culprit causing the...
Good morning!
I have 220V to a motor wired Delta, it's rated current is 13.2A. The draw is 16A and tripping overload.
Megger readings are good, resistance shows slight difference between windings, however inductance reading
on two windings is 9.3mh the third is 9mh.
Would .3mh indicate a...
