DeWalt radial saw motor wiring question
I need some advice concerning a DeWalt radial saw motor. It will
potentially be used for a metal cutoff saw but I can't figure out the wiring. It is a single phase, capacitor start, about 1.5 h.p. The cord coming out of the motor has one each of a green, black, white, and red wire. I have gone to the DeWalt website and found a wiring diagram that tells me the green is ground, black is hot, and white is neutral. All that makes sense but the red wire is shown connecting to the power switch at the far end of the motor and to the capacitor at the motor end. Ufortunately they don't show the internal connection diagram of the start switch so I don't know what the red wire gets connected to if anything. I have connected the other wires (color to color) to a pig tail with a 110v. plug. When plugged in the motor seems to work just fine. Is it possible the saw uses some sort of electronic braking? Hope someone has one of these and can shed some light. Thanks in advance. -Dean |

DeWalt radial saw motor wiring question
DeWalt did have saws with braking. They were a green color with a gray
or beige spatter, had a cast aluminum arm cap with a red circle in them. Mfd from about 1964 on up until they went out of business. All these Green spatter finished saws had brakes. All of themwould run on 120/240 VAC as well. Sure is a shame to use such a good saw as a DeWalt for a metal cutoff saw. I kow when we used ours to cut rebars etc the motor did not last long. A replacement back then was a small fortune, probably next to impossible to find one today. DeWalt also had a line of gray coled machines that were supposed to be contractor duty, and were similar to the GW and GM models, one of which had a duplex arm. I do not know if these had brakes on them or not. If its only a 1.5 hp I assume its an 8" or a 10" at the most. Dewalt , then Lancaster Machine tool, then later Dewalt AMF, and finally Black & Decker Dewalt. A lot of the original style Dewalts are still made by a company now called Original Saw Co, in Iowa, and parts are available from them and also Wolf Machinery in Iowa. YOu maya be able to find somehting out by contacting one of the above companies. They do have an online parts and tech section on the saws as well.

DeWalt radial saw motor wiring question
What is the arbor size? The 3 hp 12" saws prior to 1966 had 1" arbors. Since then they have cut them down to 5/8" Is the top of your saw flat or does it have a crown to it? The ones with the rounded arm are top of the line DeWalts.........not that there is anything wrong with the other ones though. Oh never mind, I see you do not have the entire saw, just the motor and yoke assembly..Still a good find no less. On 25 Mar 2004 15:22:01 -0800, (Dean) wrote: ===Thanks for the info Roy.
