Leeson 3 phase motor wiring

Roy,

Are you sure you don't mean 6 leads numbered 1through 6 and a #8 lead which is ground ?

If this is so then std. hookup should be: line 1 to (1 and 2) together; phase 2 to (2 and 4) together; phase 3 to (3 and 5) together.

Thanks for the link. The Leeson site was much less helpful.

I think you meant "line 1 to (1 and 6) together" but that still doesn't seem right on this motor. I won't have a chance to look at it some more until tomorrow. Think I'll get the sensitive ohm meter out and check things more closely.

I need to make some sort of switch or starter relay. I just hate plugging 3 phase twist locks in under load. :)

More later.

Robert Sw> Roy,

Robert Sw> Roy,

I wasn't seriously thinking about just plugging it in! This project is slated to have a VFD after I find a suitable motor so this is just temporary hookup for speed and power draw tests. I'll have to dig in the projects box for a 3 pole relay. I know I have a multipole toggle switch with suitable ratings but I'm not comfortable with doing testing with it. Fingers get too close to the source of the magic smoke.

I picked up several boxes of various relay's, c> Take a look at

phase 2 to (2 and 4)

An update.

I got a chance to look at it more carefully. 1 to 2 reads 1.1 ohm. 3 to

What does 4:1 read ? is it a delta or a wye and are 5 and 8 center taps or taps on two windings ? - e.g. 7 reads xx to 1...

Any one want to do an "I should have told you so"????

I was told the offending motor was a 3 phase unit. I needed a 3 phase for the project, I BELIEVED the motor was a 3 phase. So I conveniently ignored the cap in the bump on the case. And I even ignored the starting switch to the cap when I tore it apart.

Turned out to be a dual voltage, cap start, 208/240v, s> An update.
