How can you tell the differece from a three phase to a single phase motor wiring? With no data tag.?

How many power leads does the motor have? It will have four or five if it's a three phase motor (Three phases, common, and probably a ground)\n\nWhat color are the leads?\nThere is a key to the colors in the referenced link under sources . . .

Look into some system info tools. There are many free ones out there that will give you the ID of various components in the system. Try a search for AIDA32. It's a good, free utility.

DC series wound motors and generators are the same thing. One you apply mechanical power to and you will get a rippled DC wave form out. The more commutator bars (or magnets) there are the less ripple you get.\nAlternators (generators) are like you find on a car and in the generator sets that power the world. They have rings that go all the way ring the armature instead of the slits in commutators. This means that as the armature spins through the fields of the magnetic an alternating current is induced through the winding and out through the two rings. This is better for the transmission of power over distances rather than DC. So two rings are single phase, three rings are three phase. \nThe difference in a car is that after the AC is produced a set of diodes rectify the current and then a regulator levels it to 13.8volts DC cause batteries dont like AC.

i have only seen 120v motors in these ovens to be sure look @ the motor id plate. if this oven uses electric heat instead of gas the elements will be wired for 3 phase power and could possibly be converted check the wiring digram or intsallation guide

hey man I had a banshee that did the same thing. My problem was the stator. also check the cdi box and the plug wire. good luck.

Single phase circuits have two terminals one "hot" and the other ground.  v(t)=120*cos(2*pi*60*t)\n\nThree phase have three hot terminals (each 120 degrees out of phase with one another) and one ground:\nv1(t)=120*cos(2*pi*60*t+0 deg)\nv2(t)=120*cos(2*pi*60*t+120 deg)\nv3(t)=120*cos(2*pi*60*t+240 deg)

Single phase usually refers to AC power. The voltage and current in AC power alternates, and when plotted it will look similar to a sine wave.  Commercial AC power is generated and  transmitted in three phases, 120 degrees apart.  So single phase is one of those phases.  Homes almost always have only one phase, comercial locations can have three phases.

The addition of a neutral wire with a three phase electrical supply allows a lower voltage, single phase sub-assembly or appliance to be powered by the same line in (one phase to neutral).\nThree phase alone merely conducts between phases.

Simply put, the generator voltage (volts), frequency (Hz) and power (watts) and phase (single/three) are called ratings. These are selected to suit the load that will be connected. and the environment in which it will be used

WYE connections reference the line values of current and voltage to a "hard-wired" neutral. This means  \n (line voltage) = 1.732 * (phase voltage)\n (line current) = (phase current)\nThis is a much easier system to use when manufacturing an electric machine ... there will be a "neutral" - complete with leads - that can be used when troubleshooting.\n\nDELTA connections reference the line values of current and voltage to a "theoretical" neutral. This means \n (phase voltage) = (line voltage)\n (phase current) = (line current) / 1.732\nBecause of the "theoretical" nature of the neutral connection, the winding can experience far harsher effects from harmonics than the standard WYE version. Thus it isn't used as often in large machines ... although it's fairly common in smaller (<100 HP) designs.\n\nAny 3-phase machine can be used in either format; in fact, most multi-speed windings employ one of each.\n\nThe simplest advantage may come when looking at transformers, though. With a WYE-DELTA transformer, there is no possibility of ground faults between the input and output sides (unless, of course, a major accident happens!). IT also has an immediate 1.732 ratio in terms of voltage/current ... even if the turn count is the same on both sides.

Just tradition and how they set up their power grids.  In the US we use 120/240 single phase at 60 hertz for residences and some larger buildings, depends on the application.\n\n208Y/120 3 phase is much more efficient for lighting.  However the problem with 3 phase equipment is that it's normally larger and more expensive and when a lot of structures were built owners were more concerned with the build cost of the structure than the operation cost of the structure.\n\nAlso there's residential equipment that is not readily available in 3 phase configurations.

Inductance is the "definite answer" that I was given 30 years ago. I don't suppose that my confirmation is any better than yours, but it's a vote anyway.

Well, you see, that isn't done.  When you need single phase power, you use only one phase of the supply circuit.  Each of the phases of the 480 volt 3 phase power will be run through a separate transformer to step the supply down into 3 phases at 120 volt.  Typically, a house is served by two of those three phases.  You use two phases with two hot wires and a neutral to get 240 volt power for your oven, range, dryer and water heater.  The other circuits in the house are served by one phase or the other at 120 volts with one hot wire and a neutral wire.

You can sometimes look in your owner manual and find out helpful info. You can sometimes call or contact the manufacture or fabricate and see if they will send you info or part breakdown. Granger can send you part diagram through fax and mail. The vendor that you bought the ‘thing’ from can some times help. If not find out whom does the service call for the vendor and see if they can help you. Be cool when talking to them because this is how they make there living. If you are looking for a free www. ect.com. e-mail me at fryreartechnology@yahoo.com with more info and I will try to help you if I can.
