If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.

Can i wire a 7.2 volt motor up to a 18 volt battery will it just burn the motor out?
you can but if you do, you will/might: A) kill the motor,B)overload your 18 volt power supply, and C) maybe short a breaker if your power supply is also an ac to dc converter
The motor states it is 230V single phase to operate. Does that mean you need two 120V lines in and just a ground with no neutral?
Answer for USA, Canada and countries running a 60 Hz power supply service. The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get a 240 volt output because L1 and L2 are adjacent to one another. If the rating plate on this motor says 230V and it has a brown wire (the 230V "hot" or live"), a blue wire (the "neutral") and a yellow/green wire (the "earth" or "ground") it was designed for use in Europe or other world areas which use a 50Hz supply. Those wires mean it requires just one "hot", running at 230V and a neutral. In 50Hz areas that neutral is connected to earth (ground) back at the breaker panel. If you are planning to use it in a 60Hz area, such as US or Canada, it would be wise to determine exactly how the ground wire is wired inside the motor. Check it by using a test meter: if it was made in the past 30 years or so the earth/ground wire should be connected only to the frame of the motor and should not be connected to the neutral wire in any way. If you are sure that is the case, then you can use the motor but only if you do not use the 60Hz supply's neutral, which is the white wire. Connect the motor's brown wire to one of the 60Hz supply's "hots" - say the red. Then connect its blue wire to the 60Hz supply's other "hot" - say the black. (It doesn't actually matter which hot goes to which.) Be sure to connect its ground wire to the 60Hz supply's ground, which is green or bare wire, and do not connect the 60Hz supply's white neutral at all. Just leave it blanked off inside an insulated connector or wire nut.If it is an old type of 50Hz motor it might have a red (or, in newer models a brown) 230V hot wire with a black (or, in newer models a blue) neutral wire with plain green (or yellow/green) ground wire. If, using a meter, you find the motor's ground wire is linked both to the frame of the motor and to its neutral wire, that link to the neutral will have to be cut before you try to use the motor. Leave the ground wire connected only to the motor's frame. If you don't make sure that link is cut so that the neutral is no longer connected to the ground wire, you will have big problems when you hook up the motor because, back at the breaker panel, the 60Hz supply's neutral is connected to the ground, so if that link within the motor had not been removed, it would cause a short to whichever 60Hz hot (red or black) you connected to the motor's neutral wire! Note: if the motor does not have brushes running on an armature then it is a squirrel cage or similar type induction motor, which means that, running on 60Hz, it will spin at a speed 60/50 of its rated design running speed. That is 20% faster than it would spin at 50Hz, so it would be wise to check that the higher speed is suitable for the equipment you want to use the motor for.

Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.
How can you connect a 120 volt motor to run with 240 volt?
Answer for USA, Canada and countries running a 60 Hz supply service.Use one leg of the 240v and the neutral wire. Most electric dryers run the motor this way. The heating element is 240v but the motor is 120v.NO, THAT IS DANGEROUS ADVICE because a 240 volt service has a circuit breaker which is sized for the current draw of a large 240 volt appliance, so it would have a rated amperage that is too high to protect a 120 volt motor running on its own.Only 240 volt appliances such as dryers, air conditioners, etc. are safe to use on 240 volt circuits.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How much copper in a 100 HP electric motor 100 HP electric Chicago air compressor motor?
The amount of copper in a particular motor is not determined by horsepower only, there is no relationship between the total weight of MAGNET WIRE to the HORSEPOWER of an electric motor. Determining factors are the vintage, frame, make, speed, and frame designation.
What is the correct way to wire an electric motor capacitor since the capacitor is not marked?
Motors that use capacitors are single-phase AC motors. The capacitor is used to "start-and-run" the motor. The capacitor is wired between the incoming hot service wire and the "start-and-run" terminal of the motor. The other terminal of the motor is connected to the outgoing neutral service wire. These capacitors are designed to run on AC (two DC capacitors back-to-back) so It doesn't make a difference which way round the two terminals are wired. If the case is metal it is usually grounded to the ground wire. Some motor "start and run" capacitors are plastic-cased so don't need any ground wire.
What brown colour wire indicate in a electric iron?
Brown is the "hot" wire and blue is the neutral on a UK 220 volt power system.
What size wire do you need for 20 amp 220 volt electric motor?
For a 20 amp 220 volt electric motor, you would typically want to use a wire that is rated for at least 12 AWG (American Wire Gauge) to ensure proper power transmission and safety. It's always best to consult local electrical codes or a certified electrician to ensure compliance and safety.
Wiring 240 volt electric motor?
To wire a 240-volt electric motor, connect the two hot wires from the circuit to the motor's line terminals, usually marked "L1" and "L2." Connect the motor's ground wire to the grounding system. Make sure to follow the motor's wiring diagram and adhere to local electrical codes.
Does 240 volt have a neutral wire?
Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
Is red or white neutral for electrical work?
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
Is a common or Neutral wire needed for all 240 volt circuits Example will a 240 volt electric motor run without a Neutral wire?
Answer for USA, Canada and countries running a 60 Hz power supply service.It all depends on the type of appliance!Some 240 Volt appliances, such as some electric motors, DO need to have a Neutral wire. Some of these appliances have timers or other devices inside them which only require a 120 Volt power supply, hence they need a Neutral wire to get that.Other appliances, for example some household electric clothes dryers, DO NOT have to use a neutral wire because they only have a very simple heating element connected just to the red and black "hot" legs of the supply. (One hot leg is actually 120 Volts above Neutral when the other leg is 120 Volts below Neutral. But remember, as this is alternating current, they both alternate 60 times a second, going from zero to +120V to zero to -120V and back to zero again.)However a dryer should always have a Ground wire connected to its metal casing to protect users from possible electrocution and prevent a house fire. Such a ground wire helps ensure that the circuit breaker or fuse will cut off the power supply if a fault occurs within the appliance or its power outlet. (But that has nothing to do with "needing" a connection to a Neutral wire.)IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.
Can you use a neutral wire from a existing 110 volt 20 amp circuit to supply a neutral for a washer dryer combo that has only a 220 volt 30 amp 2 wire?
No !
Is red neutral or live in a 240 volt system?
The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
How do you wire a 120 volt gfci into a 240 volt three wire?
You can't. The 120 volt GFCI is probably just a 2-wire (hot, neutral and ground) You would have to run a new 3-wire (2 hots, neutral and ground). The two hots are how you get the 240 volts (120+120=240). Also you must make sure the wire is gauged properly. #10 wire for 30 amps, #12 wire for 20 amps, etc.
Why neutral wire doesn't give electric shock?
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
