Why generator has the better efficiency than motor?
becoz alternater has work on principle of electomagnetic induction .
Why generator has more efficient than motor?
Depending on what you're referring to, you may have this completely backwards. A motor's efficiency is fairly high. A generator's efficiency at converting chemical/kinetic/mechanical energy to electric energy is at best around 50%.
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!
Why the efficiency of generator is more than the motor in case of swinburne's test?
the generator windings are made of more thicker windings . Hence lesser resistance and lower Cu losses
What happens if the synchronous motor exceeds its load capacity?
If load on a generator is greater than the generator can provide, the generator will begin to slow down. If it slows down too much, it will lose synchronism.
Difference between induction motor and induction generator?
in case of induction motor the rotor speed is less than synchronous speed giving positive slip but in case of generator the rptor speed is greater than synchronous speed giving negative slip.......
How do you prove that the efficiency C arnot is greater than 1?
You don't. Such an efficiency can be less than 1, but it can't be greater than 1.
Can a motor act like an electric generator?
when the motor runs more than rated speed it produces leading current and results act as a generator. (or) the motor act as generator when it produces more back e.m.f
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.
If a three phase induction motor runs at a speed greater than synchronous speed?
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
How is an electric motor different than an electromagnet generator?
Some types of motor can work equally well as a generator. A DC motor runs on a DC supply and supplies a mechanical load. If the load is removed the motor will free-run a little faster. But if the shaft is then driven faster than that, the current flows the opposite way and the motor has become a generator.
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.
