I am convinced my 14” Delta 28-280 platinum edition closed base 1 HP open drip proof motor doesn’t really put out 1 HP and I’m thinking of upgrading it to a 1.5 tefc motor. I think existing motor is an Emerson motor. It is a nema 56 frame and I think CCW rotation running at 1725 rpm. It does not have a riser as I don’t resaw more than 3-4”. I have 220 in my shop so if I could find a 2 HP motor that fit would also be an option. The motor bogs down with a sharp blade and it is well tuned with coplanar wheels that aren’t eccentric and are well balanced. Thrust bearings are fine. Cool blocks. Well tensioned blade. I have also blown out dust from motor and not a whole lot of dust gets into the motor enclosure. Motor is clean. Cogged belt is in nice shape. So my first suspicion is that it is the Emerson motor.
Is there a way to test the motor under load to see if my suspicions are correct? I’ve read this particular motor really sucks and not worth rewinding. A 1 HP motor shouldn’t bog down on a 4” resaw with a sharp blade (1/2” 3 tpi bimetal)?
Has anyone sourced a 1.5 HP tefc nema 56 or 56h motor 1725 rpm that will bolt on from lesson baldor weg marathon or similar manufacturer? There isn’t a whole lot of space in the enclosed base and I don’t want to redrill the base to move the frame over to make more space. I also don’t want to modify the base to create more space. I’m looking for a motor that will bolt in without much fuss. :). I suppose an open drip proof would also work bit I’d prefer a tefc. Thanks. Tom
PS. I’m not interested in getting a new band saw. :) In retrospect I wish I would have bit the bullet and bought a MM16 or a Laguna but for what I do other than resawing the Delta does what I need it to do.
