How do you wire a 4 wire cable from a generator l14-30r plug to an electric motor with 3 wires?

A L14-30R is a three pole four wire grounding 125/250 volt receptacle.
It is designed to supply voltage to a three wire system much like the connection to a range or clothes dryer.
The generator connections to the back of the receptacle are; blade hole with indent inwards is the ground.
Left (X) and right (Y) of the ground pin is the 240 volt output.
The last blade hole (W) is the neutral wire connection.
(X) to (W) will be 120 volts, (Y) to (W) will be 120 volts and (X) to (Y) will be 240 volts.
Check the nameplate of the motor to make sure that it is not three phase hence the three wires. Without more information about the motor a complete answer can not be given.

Will a 2800 watt generator run a 550 watt electric cement mixer motor?
The sizing of the generator is dependant on the size of the electric motor driving the mixer.
What two machines that you use today are based on Michael Faradays findings?
electric motor and electric generator
What percentage of copper in Electric generator?
The amount of an electric motor's copper depends upon the size of the motor and the supplies used to make it. Generally, the older the motor, the more copper will be present.
Can you take a 12000 watt gas powered generator and replace the gas engine with a electric motor to run the generator?
A 15 KW generator won't likely run everything in your house, but besides that it is not efficient. You will be using more electricity to run the generator than the power would deliver. You also defeat the reason for the generator - run your house when power goes out. Now if you had a wind turbine turning a generator you have a positive contribution to house power. This is how wind power works. There are also lots of issues associated with a power transfer switch and feeding power back into the grid.
What is back motor effect in generator?
When current is induced in the rotating coil in an electric generator then a counter couple acts on the current carrying rotating coil in the magnetic field(in accordance to the principle of dc motor). This counter couple is called back motor effect.
What is the opposite of a generator?
electric motor
What is a backwards working electric motor described as?
Electric Generator. :)
Can an electric motor be used as a generator?
yes
What are similarities and dissimilarities between a motor and an electric generator?
An electric motor converts electrical energy into mechanical energy. While an electrical generator does the opposite.

The sizing of the generator is dependant on the size of the electric motor driving the mixer.
What is the background of the study of generator from a toy motor?
It has electric!
Invented the electric generator and motor?
Nicola Tesla
Who is the invented the electric generator and motor?
Thomas edison
What device is like the reverse of an electric motor?
A generator.
How does ac electric motor convert in to an alternator?
a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.
Can an electric motor run a generator to power itself if the motor has a small gear and the generator has a big gear?
I think it can work with a certain type of generator and an electric motor like one that uses 300w/h The idea is to run a generator that can produce more electricity than needed to run the motor that is powering it.
How do you turn a 3 phase motor in to a generator?
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
