As the name implies, a motor-generator set utilizes an electric motor as the prime mover to drive a generator. The motor and generator can be mounted on a common shaft or they can be mechanically connected through a coupling, belt drive system or reduction gear.
In all cases, the motor requires a source of power (from whichever electrical supply service is available) and it drives the generator to produce the required electrical output power. For instance, if a single-phase supply service is the only service available at a location, the generator's output could be three-phase ac which could be used to supply power to machinery which has three-phase motors, etc.
If a site has equipment which requires only direct current the generator could be one that produces dc. That is a less common setup because a full-wave rectifier could easily be used to produce plain dc from ac, but a motor-generator set can still be used for very specialized applications which need highly accurate control of a dc motor under varying load conditions. The Ward Leonard Drive System is a specialized example of such a motor-generator set. (See the Related Link below for more information.)
Nowadays, because high-power electronic inverter units are sold to produce a three-phase service from a single-phase service, motor-generator sets are used mainly for very specialized industrial sites, for engineering development and for scientific research applications.
It should be noted that there is no need to use a motor-generator set or an inverter unit to produce single phase from three-phase because any one line of a star-connected three-phase service, along with a neutral wire connected to the central star point, can easily be used as a single-phase service.

What else can I help you with?
Can an ac motor generate electricity?
An ac motor cannot generate electricity but its shaft can be coupled to that of certain devices like an alternator to in order to generate electricity.
What generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
What generates more noise ac motor or dc motor?
dc motors generate more noise.
Will running a motor backwards generate power?
No. Motors can be run in either direction, clockwise or counter clockwise. However, mechanically spinning an electric motor will generate electric power.
Can you use a 24VDC-100RPM motor as wind generator?
All DC Motors can generate electricity according to their size & input volt. 24 volt DC Motor is best for generate electricity. Even you can generate up to 24 volt AC. The big size of Motor is also depends to generate more ampere (current). Remember 24 volt DC Motor which have less RPM without gear is better & efficient for generate electricity than having the more RPM (Round Per Minute). So try it & generate electricity.

Can a motor produce current?
A normal ac motor has a squirrel cage rotor that is made to turn with a changing magnetic field. If you move a magnet in a conducter it will generate a voltage, therefore the rotor will not really generate a useable voltage. It does generate a little bit but if you load it it will go close to 0 Volts. If you have a correct magnet in place of the rotor it will generate a voltage.
How do hybrids generate electricity?
They run a gas powered motor which charges a battery.
Capacitor?
capacitor is a power cell used to generate electricity in the motor of ceiling fan
What makes a windmill generate electricity?
the wind turns the rotor which turns a motor which generates electricity
Which conversion takes place in a motor?
Electrical to mechanical energy conversion takes place in a motor. The motor uses electricity to generate rotational motion, which can then be used to drive various mechanical systems.
What are electromagnet in motors used for?
A motor is essentially two sets of magnets pushing against each other. So the electromagnets in a motor are used to generate a force to provide torque and spin the motor.
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
