I am no Motor Repair Genius but I can very well figure out how a connection is made and if it is wrong.
You know that I am have been fixing the FSM petrol pumps and anything and everything related to electronic to electric and even to sometimes mechanic [ In mechanics, I have to first figure out how the friggin thing works in order to fix it]
They are warned not to call me unless they have no other choice. Cause then I can squeeze them dry .
And the best part is they know that,and yet they destroy the thing almost completely by their techs or another low class electrician who just has the basic know how in household wiring. Don't u just think it is great here.
{ I think it's about time them Gilberco guys train me as a certified guy in Maldives. Don't u think ?}
Story time.
Now these Motors are HVAC motors [ I dunno what tht means but I have figured tht it is some what air leak proof or something as the motor is used in Petrol Vapor involved areas]. It is labelled Explosion proof, and all those fancy safety working level things. So to say this bugger is pretty expensive since it's operation safety concerns human lives.
The Motor is made by Franklin Electric.
Rated at 3/4 HP, 220VAC, around 1500rpm, continues operation.
And is a capacitor Start, Capacitor Run motor, with a centrifugal switch inside.
A few weeks ago one motor stalled.They have been trying to get one repaired together with a local tech for quite sometime. The centrifugal switch was totally destroyed, I dunno when tht happened. It may have been during the operation or it might have been while they dismantled it, as the wiring are pretty tight and any open holes where the wire comes out are filled with epoxy. All in all more work for me with higher pay checks
I bet the tech gave up and did not pick up their call so they called me. The Evil genius.
A couple of motors were there. Nothing works, no center switches and no good capacitors. And the capacitor they had are just too darn huge to go into the housing of the motor. And they were planning to put some sorta timer to cut the start cap when the motor picks up speed. The caps were now planned to be mounted else where inside the termination box which the SS relay and the wire terminations are. It will be safe since all the motor and box plus wiring are housed in metal. Even the wire that comes from the motor to termination box is contained with in a steal pipe.
Then I did not know the caps were supposed to be inside the motor end caps. Cause when I saw it, two caps were already outside the motor. So Naturally I figured they will be outside since I have seen them. But I never new 'em Gilberco guys had put the caps inside. And this turned out to be pretty bad assumption from my side. I made a mistake in trusting them techs. I should have known better. Sigh !
Something must have been done way before I got involved with a motor, I say this cause this is my first attempt in fixing one. Before I never got to touch a motor besides the electronics.
So the problem was [which I assumed], since the motor field wiring , center switch,thermal cut out and the caps are made inside the motor, there were only three wires coming out. They forced the thing open, broke the wires and all hell got loose. So now they had no idea which freakin wire goes where. Since the caps are located at both ends, one at the back and the other one on the end. Wires were going in side the field which actually has no connection to the coil. So this made the job a whole lot more confusing to them.
They cut off the wire took the cap out made some sorta connection I really have no idea about put the new caps outside {since the old ones didn't work} and ran the motor fro some time and gave up.
So to say I am not sure about the history of these things.
From now I will tell you what I saw and did.
So from this point is what actually went on after they called me.
I went to there workshop and they wanted me to get the motor running.What I first saw was a Franklin Motor which has so many wires coming out { I never new then it is not how it shud be}
But they had two types of Motors. One that came with the pump and other two made from china. I dunno what they call them, to me it sounded like wooo yung chin chon motor or somethin. The label says in box Chinese letters, so I called them wooyun motor and the other one Gilberco. Now I can identify them seperate
They both were almost the same but the wooyun turned the wrong way which is CW. The Gilberco ones were CCW. They have destroyed two of them center switches while trying to figure out how to turn them CCW . And these wooyun's were totally brand new.I can see from the fresh paint it has.
They cannot get it running either way now, so now they planned to fix the gilberco one and a local tech has bought some new caps. A 300μf one and two 20uf ones (this was the biggest mistake in the first place. U will know later) PLUS A TIMER. The new guys plan were to use the timer instead of the centrifugal switch.
"I was wondering how a uneducated tech who has no freakin knowledge on induction motor what so ever gonna time a freakin timer to cutoff at the right rpm with out a tacho"
I like totally blanked staring the office guy. "What in god's name were u trying to do? ", I asked even though I knew he cannot answer. I just had to ask.
I was LMAOF
