Electrical for a motor, General electric 110 volts, 1725 RPM?
It has three wires, orange, blue and black. I want to use it for a bench buffer on one end and wire wheel on one the other end. I put the black alone and the orange and blue together, it smoke and overheats after awhile. Which wires go together Or ? the black alone and the orange and blue will make is heat and smoke. Or?
There is a green ground wire, no name plate, come off a sears dryer about ten years old. Double shaft.
The blue and orange wires are in the same shethe and go inside the motor, the black is alon and also goes in the motor, there is a separate green ground, the motor is sealed w/two safts, one on each side, no plates or diagrams. It runs with the orange& green together and black separate but, after awhile (5 min) it starts overheating.

Look on the name plate and see if it shows how to hook it up. Also look on the inside and outside of the cover where the wires are. 1725 rpm is a split phase motor. The options in the wires are for the rotation direction. There was usually a terminal block you connected the line/ feed wires to and then the black, orange, and blue connected to that board. Usually the directions will say something like swap black and orange to change direction.
Electrical devices only come with so much 'smoke' installed from the factory. If you let too much out already you make be looking for a new one soon.

Sounds like you have a 2 speed motor and you are running both speeds at the same time causing it to get real hot. The name plate usually tells what the wires go to. There should be a small wiring diagram either on the motor or in the box it came in. If you OHM out the wires to each other the 2 wires with the highest reading are the speeds and the 1 thats left will be common. Do not hook the ones with the highest ohm readings to each other, only hook 1 up and put a wire nut on the other.

Black is almost alwas the ground wire. Orange and blue are not what I consider to be "standard" colors for wiring, but one wire si for electricity going to the motor, and the other is for it to go the other way. The only thing I "know" for sure, is that if you connect these two wires incorrectly, is that the motor will (should) run in the reverse direction than it should, if it runs at all. If it either does not run, or runs with the wheels turning from the bottom to the top (they should run from the top to the bottom), reverse ONLY those two wires.

One of these wires (most likely the black) is a "case ground" wire. You can determine which one for sure by following them to where they are connected. The case ground will be attached to the metal of the motors housing. This wire should ONLY be connected to the grounding bar for your breaker box, this is the third (ground) wire on a 3 prong 110V receptacle. NEVER TIE THIS WIRE INTO THE OTHER WIRES. BY TYING THIS WIRE INTO THE CIRCUIT YOU ARE ELECTRIFYING THE MOTOR HOUSING. Since you are still asking questions I assume you're lucky and didn't learn this the hard way. The other two wires from your motor will then be the "hot" (current carrying) wire and your neutral wire. If you have already let the smoke out, the motor is more then likely junk.
