Stators

[Pin_Head]

i have yet ANOTHER bewildering problem ( you probably think by now my machines suck LOL) well anyway, im more familiar with GE combination gearboxes and stators than i am with westinghouse and the center im at use mostly westinghouse. Well what confuses me is that if you look at a schematics diagram or the installation manual for these new SS Start switches it clearly shows the stators having : Dual Voltage; 3 pairs of windings
2 run and 1 start
Single Voltage; 2 pairs of windings
1 run and 1 start.
Here is where im confused, if you have 3 pairs of windings you have 6 wires coming out of your windings, and 2 pairs you have 4 wires, so can anyone tell me why my Westinghouse stator has 8 wires coming out of it.

p.s. Sorry for making that very drawn out and boring.

Re: Stators

What are the Ohm values between the wires, are there more than two wires connected with each other inside the stator?
Try to find out how many coils you have.
Sometimes there's a coil with a connection in the middle of a coil.

Re: Stators

G'day Pin_Head,

My guess is that being Aussie stators ( 240 / 115 Volts ) you have 3 Windings ( that 6 of the wires covered ) & the other 2 are ?? something else .

Not at work at present , but I'm sure that we have a Westy off a machine in our parts bin (Most of our stators are GE's but there are Westies & Nationals floating in the house , If I get time I'll see what I can find out

I'll guess that the SS start unit is a "CYBERNETICS" unit ( If it is not ,WHY would you buy any other brand ?? )

Ray Jordan from Cybernetics is a frequent contributor to Bowl Tech & a helpful guy , I'd give him a call ( # should be on the Instruction sheet )

They are just down here in Sunny Melbourne so the phone call won't break the bank

Cheers,

Mark

Re: Stators

Pin_Head ,

I'm not sure where my brain was when I posted my last comments , I suspect that I have been seriously Hallucinating recently due to eating Bowling Alley food 6 days a week for far too long

We don't have ANY Westinghouse Combi motors on any of the 28 machines (82/70c English Built not US ) or in the workshop .

I pulled out the trusty 1972 AMF motor rebuild book & had a look see .

The books shows the Westinghouse stator as having 2 windings :-

Start ( 4.2 Ohms ) Red & Black wires
Run ( 1.5 Ohms ) Yellow & blue wires

These are straight up 110 / 115 Volt stators with no 240 Volt windings .

Other wires are Brown & Purple to the Klixon

Red & Black to the centrifical Start Switch contacts

Total of 8 Wires .

Not sure if that helps , But this may

Measure for Pleasure first!
Sometimes you don't need all the wires or sometimes you have to connect them...

Re: Stators

Have a look at the switch board, you might find that some wires go to terminals that nothing else connects to. This is just to make the 110/220V possible.
Intertwined in this is the combo capacitor situation, necessitating five prongs.
Just hook it up for whatever your voltage there is, and don't worry about the other wires. They designed it that way. Seriously.

Mainly so that it can be tested in America at 110 and rewired to run at the same speed and torque at 220 wherever it's sent, but that's beside the point.

You are at an advantage in that your rotors are much longer than our 052/508 versions. That means there's a lot more metal available to magnetize and turn than the wimpy ones that we at 60hz have.

Hope that helped,
