There is 746 watts per HP. So a 350 hp motor with a power factor of roughly 0.8 would require 261,000 W 261KW generator or 326 KVA.

What is the application of generator and motors?
A generator converts mechanical power into electrical power. A motor converts electrical power into mechanical power.
Why DC battery is required for generator?
The starter motor of a diesel generator is a DC motor. Depending on the size of the diesel engine the starter motor could be 12 volts or 24 volts. Sometimes more that one battery is used at the specific voltage. These batteries are connected in parallel to create more amp hour cranking power.
Is it possible that you use motor as a generator input and electricity of the generator provide to a motor as a input?
If I'm understanding the question, you are proposing using one motor and one generator, and have the motor spin the generator up to speed, and have the generator attempt to supply power to the motor. The answer is yes, you can do this, but you will be losing energy, not gaining it. The motor and generator's efficiencies are less than 100%, so once you remove the outside source they will slow down until they come to a complete stope, without any other load connected other than themselves.
What is the problem with using an electric motor to run a generator stepped up with transformers that is used to run the motor and give electricity for other uses?
It's all to do with the conservation of energy. The output power of the transformer cannot be greater than the input power from the motor used to drive your generator! In fact, it will be significantly lower than the power of your first motor due to the efficiency of the motor, of the generator being driven by that motor, and of the transformer. So if you then try to run the original motor from the output of your transformer, the energy-losses will simply accumulate, and the motor will not be able to run!
When the induction motor working as induction generator?
An induction motor connected to an existing ac supply normally runs at less than the synchronous speed by an amount described as the 'slip' which is proportional to the torque demanded at the shaft. If the same motor is instead coupled to an engine and driven at a speed higher than the synchronous speed, with negative slip, power then travels back into the ac supply and the motor has become a generator. The amount of power produced depends on the speed. However a normal induction motor will not behave as a stand-alone ac generator. For ac power generation synchronous generators are invariably used because it is necessary to set and maintain the frequency of the supply accurately.
Can a motor operate as generator?
Yes, by giving mechanical power to motor . It acts as a Generator.
Could works a 500 watts of power and 3 phases motor with a wind generator?
Yes, a wind generator can power a 500W motor with 3 phases. The power output of the wind generator needs to be sufficient to cover the motor's power requirement. Additionally, the wind generator must be connected to a suitable inverter to convert the generated power to the required voltage and frequency for the motor.
Why load angle is positive for generator and negative for motor?
simply put a motor consumes power and a generator produces it. reactance of a generator = - reactance of a motor
What is the application of generator and motors?
A generator converts mechanical power into electrical power. A motor converts electrical power into mechanical power.
What is the difference between an electic motor and an electic generator?
AC motor produce mechanical power and absorbed electric energy the power generator produce electrical power absorbed mechanical power
Can an electric motor run a generator to power itself if the motor has a small gear and the generator has a big gear?
Yes, it is possible for the electric motor to run a generator to power itself through a gear system, with the motor having a small gear and the generator having a large gear. This setup can create a mechanical advantage that allows the motor to turn the generator efficiently to produce electricity, which can then be used to power the motor.
When the motor is doing some work at the same time can it generate power with help of another generator is this possible like this anything there?
You can't use a motor to power a generator and use the output of that generator to power the motor. Some energy will be lost at each step making the hookup pointless. But you can use a combustion engine to power an electric generator and use that electricity to power auxillary systems around the engine.
How does the generator terminal voltage rise and the motor speed fall when the brushes are given a backward shift in a generator or forward shift in a motor?
A generator is a back up of power. A generator can only give so much voltage.
Can you run a AC generator with help of a DC motor if yes how if no why not?
Yes, but the power you get out will be much less than the power you put into the motor.
Why DC battery is required for generator?
The starter motor of a diesel generator is a DC motor. Depending on the size of the diesel engine the starter motor could be 12 volts or 24 volts. Sometimes more that one battery is used at the specific voltage. These batteries are connected in parallel to create more amp hour cranking power.
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 are the differences between the parts of a generator and the parts of a motor?
In principle a generator is the same as a motor. In a dc motor the voltage generated by the rotating armature is slightly less than the supply voltage which causes power to flow in from the supply. If an engine is then coupled to the shaft causing it to rotate faster, then it generates more voltage and power flows back into the supply. That is how a motor becomes a generator.
