how hot do you run?

[Table Head]

I've got some westinghouse B/E motors that run pretty hot. One runs about 140 F. Is this the norm for these, all but 19 of my machines run nationals.

If you Westies B/E get to 150 F - 160 F then you are looking at some resistance in the stator windings. They can run hot. Most of mine run between 125 F - 145 F. I have at least half Nationals and they run a cool 105 F - 125 F.

Westinghouses notoriously run hot (as well as leak).

Sometimes I fry my diner off them on the cold winter days down the back.

Though if they are running really hot then problems are a foot. The running temperature has alot to do with how much wire is used to make up the windings. Thus effecting the ampage draw.

Usually a suspect wiring can be to blame for over heating or worst of all a bent rotor shaft eating the stator [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img]

Along with what Alasrair is saying, if your terminal board starts to get alot of corrosion around the lugs, this will generate poor connections which causes resistance.

Re: how hot do you run?

Thanks you everyone for your input. I only use my westinghouses when I have to. Love my nat's. My termainal board is fine, just did an overhal on it. But like you guys say they are great for heating up left-overs.

Re: how hot do you run?

we run AO Smith back end motors and they all run hot, a few examples run ridiculousley hot because people have milled out the stator a few thou.

they give us trouble!
