145tc vs. 145tcz

[marctheprop]

I'm looking at a Rockwell/Delta planer with a 3hp 3 Phase 145tcz frame motor. I own a 3hp single phase 145tc frame motor. Can my single phase motor be substituted/modified to fit the planer? Does anyone know what the z means? Thanks for your input

NEMA dimensions are a industry standard for electric motors. The "Z"indicates a non-standard shaft dimension. It could be either the diameter or the length that is not a NEMA standars dimension. A standard 145T motor would have a 7/8" diameter shaft with a lenght of about 2" to 2-1/4". The "C" just indicates that it's a "face mount" motor, meaning the shaft end is machined to bolt diectly to the item being run. Most likely it is a OEM motor made by Delta to speifically fit their saw. Manufacturers quite often have motors and parts manufactured to their specs so that you have no choice but to go back to them to get the right part. That way they make money all the way around.

Thanks for the info-I bought the planer after I saw it under power. I thought the bearings were a little loud so we'll see if I got a great deal or just a good deal. Now to build the phase converter... And who would think that a manufacturer would try to tie you to them to buy replacement parts? My biggest problem is that they DON'T support their products. I've got a 10 year old shaper that I can't find spindles for;one just sold on ebay for almost $200 by the time you include shipping.
