In an electrical engineering textbook you would probably find 1-2 chapters on ac motors and another on ac generators. The theory explains how these devices work exactly, and gives methods for designing them from nothing, so the theory would tell you from basic physical principles how to optimise a design, i.e. how to get the best performance from it at the minimum cost in terms of mass and the cost of raw materials.
What else can I help you with?
Is an electric motor and a generator very similar devices or entirely different?
They are very similar devices. They both involve a rotating shaft and coils of wire used as electromagnets. However, only certain types of simple DC motors, can be used as generators with no modiication. AC generators need careful control of the feild coils, via special circuits. Putting AC back into an AC generator will not make it work as a motor. The small DC motors found in toys, can be used directly as a small DC generator. You will find this in practice, in hand generator flashlights. The generator used for charging the battery, is no more than a model motor.
How is alternative current prodused in a battery?
A battery by itself will only supply DC output. You would need a method to convert DC to AC, such as an inverter, in simplified terms: an electronic circuit which has an oscillator to create the desired frequency then amplifies it to the desired magnitude output. Another way, which I don't know if used anymore, is a motor-generator set. A DC motor's shaft is connected to an AC generator's shaft, and the output is taken from the AC generator.
Is it possible to combine both motor and generator into single device?
It is possible, but in general it would be fairly pointless unless you want a very specific type of application The simplest way to do what you're proposing would be to have a motor spin an axle, and connect that axle to the generator's input. But because of the fact no system is loss-less you would be losing energy to friction and hysteresis and resistance you would be losing energy if you have a motor power its own generator. On the other hand this device could then be connected to a battery bank (through proper voltage regulators and a rectifier) and it would be possible to either charge the cells (by connecting the generator and spinning the axle) or run the motor (by discharging the cells through the motor). This is a little like the principle behind regenerative breaking in an electric car. Also, every generator is ALSO a motor, in a way, it simply depends how it's hooked up. Any AC electric motor could theoretically be turned into a generator.
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.
Why is necessary to control over speed in a motor?
over speed control is recommended for all prime mover driven generator to prevent over frequency operation of load connected to a system supplied by the generator and also to prevent possible over frequency operation of the generator itself from Ac system.
What is the theory of conversion of AC to DC using 3-phase induction motor and DC shunt generator?
The theory of converting AC to DC using a 3-phase induction motor and a DC shunt generator involves utilizing the induction motor to mechanically drive the shunt generator. When the induction motor is powered by a three-phase AC supply, it operates and drives the rotor of the connected DC shunt generator. This generator then converts the mechanical energy into electrical energy, producing a DC output. The process allows for efficient conversion of AC to DC, leveraging the motor's mechanical properties and the generator's electrical characteristics.
How do you change over a ac motor to a dc generator?
Type your answer here... how can you change an ac motor to a dc generator
How do you reverse single phase ac motor to generator?
how reversing an ac single phase induction motor to wark as induction generator
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
How do you step down frequency and voltage from an AC generator?
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
What are uses of ac generator?
give electic to motor
What kilowatt of AC generator will drive a 18 kilowatt ac motor?
30kva generators ,it can be able to run the 18kw ac motor
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.
What is rotrey converter?
Rotary convertor basically a dc motor running an ac generator all on one shaft Rotary invertor ac motor running dc generator. I think I have it the right way round
Is an AC generator can use AC motor and vice verso?
Are you planning to build a perpetual motion machine in which the power generated by an AC generator is used to run an AC motor which is used to run the same AC generator which provides it with power? Because that won't work. Yes, you can use a motor to generate electricity, and you can use electricity to run a motor, but the process is not 100% efficient and if you try to make it a closed loop, it will run down fairly quickly. So, what do we actually do? We use fuel to run an AC generator, or we use waterfalls or wind, or some other energy source, and then we use the power to run our motor.
What is static inverter?
An inverter that consists of a DC-motor driving a AC-Generator.
What is an amplidyne?
An amplidyne is a form of electromechanical amplifier in which an AC motor drives a DC generator.
