  • how hot do you run?

    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.
    There is always more to life, but would someone tell me what it is!

    Re: how hot do you run?

    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.

              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.

                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!
