  • Help determining Baldor motor h.p.

    I picked up a 3 ph. Baldor 220 v. motor, which I found out was originally army surplus. The printed or painted data on the aluminum tag is nearly obliterated. I'm trying to figure out the approximate h.p. rating. Would a 4.4 amp full load rating at 3450 rpm and at 220 volt input mean that it is somewhere between 1 and 1.5 h.p.?



    Thanks,

    I have one listed at 4.2A - 220 and most say it is just at 1.5 hp

    but yours is double the RPM of mine so maybe that makes a difference.. im sure someone will chime in

      Confused...http://www.baldor.com/products/detai...Motors_50Hertz

      that is from the current Baldor site using the "M3350T" code near the bottom of that plate, confused since it kicks back as usable for 50 Hertz and not at the rpm that is clearly also stamped on your plate...the Baldor site for me has been nearly 100% at IDing motor I have come across so not sure what is odd here...to me that plate is very clear, seen ones with other numbers/letters stamped over top, plates half missing is common.

        Pretty clear from the label that it's 1.5hp, service factor 1.0, and 3450 rpm at full load.

        Don't worry about the 50 hz not being listed on the name plate - Assuming it's rated for 50hz, it will just run at about 2875 rpm if you did.

          Russ, the nearest thing I could see on the Baldor site was http://www.baldor.com/products/detai...ing=40CMB-CONT

          It lists at over $700, so I think I may be able to enjoy a small gloat on this, since I got the motor, an Allen Bradley 20 amp power switch and a strap of 3/8" x 3" x 30" steel for $50. Motor runs fine, and the guy I bought it from said it was 1.5 h.p., but I really could not make it out from the tag. Baldor does say this is a discontinued item.
