Hey guys
I'm haven problems with a faulty motor that I have received after a sparkly have been playing around with.
Motor runs but is not right and drawing 40 amps should be 12.5
And looks like the centrifugal switchover is not connected.

Here is a very messy diagram how motor is connected hopefully someone can help me with this headache

 

That's not necessarily a "Faulty-Motor",
that's a Motor that's been "fixed" by someone who had no clue what they were doing.

You'll have to get in touch with the manufacturer, or take it to a Motor-Re-Winding-Shop,
unless You can come up with a PDF Spec-Sheet for it that has complete Wiring-Diagrams.

That's a very expensive Motor, are You sure that it's what You need ?
What will it be powering ?

Do you have the motor plate Info? Make? model? etc Pole count?.

It's drawing 40 amps should be around 12 amp that has to be a problem.
It's powering a pump set that was tested in the workshop before it went out and was all working fine

I have used WEG motors in the past and we are are fortunate to have a WEG rep Co in the district where they have been excellent in answering questions, if they don't know they contact the Technical dept.
If you have one in your area , it may be useful to try them, failing that, I am sure they could be contacted on-line.

Thanks will try them out have been into the local weg agent

Thanks mate

 

Now that we have a clear name-plate to refer to,
questions about the actual installation operating conditions are in order ........

Was the actual Full-Load Current being pulled by the Motor measured with
an Amprobe, or similar Current-Tester when the Motor was initially installed ?
What was the Current reading ?

Does the Pump run continuously for more than an hour ?
What is the pumps worst-case "Duty-Cycle", ( amount of time "On", vs amount of time "Off" ).

These Motors are built like a Brick-Outhouse, they don't "just-fail" out of the blue.

This Motor is rated for a "1.0 Service-Factor",
this means that it's running on the ragged-edge at 12.5-Amps,
if it is run under "Continuous-Duty" conditions.

Continuous-Duty at 12.5-Amps will eventually cause overheating and Winding-Insulation-Failure.
A Motor restart more often than approx. every 5-minutes can also cause overheating.

Motors with higher "Service-Factor" ratings are readily available,
or, You can simply go to a higher Horse-Power-rated Motor,
( with the same NEMA mounting dimensions ),
to obtain normal operation below the Maximum-Current-Rating.

If the wire identifications are still intact then there is hope that it can be reassembled and wired correctly.
If the wire identifications have been removed, then the sparkly that removed them should be discharged.
The big problem that I see is that there are eight wires, which include two from the internal starter switch, but only six terminals. It is obvious that the centrifugal switch must disconnect the starter windings but that area for connection is not visible.

 

And looks like the centrifugal switchover is not connected.

What was the fault before it got messed with?
I see problems with the cap circuit that does not seem to make sense !?
I would not try any random connection at least until I contacted WEG, hopefully they can shed a light on it.

 

The capacitors are two in parallel for run and a single cap for start. Dual caps to reduce heating while running. I think that I saw some capacitor connect terminals on some wires in that one photo. Do the wires have numbers on them?? that would be very good if they did.

If the two are in parallel for start, they should only be in circuit for a second or two, not enough time for them to overheat.
The run cap is rated continuous and a much smaller value.
As the OP said. looks like someone had played around with it !

The TS stated very clearly that someone had been playing around with it. I would add that it was very clearly an unqualified individual who had no ideas as to what was involved.

I think everyone agrees with that !
