Why efficiency of generator is greater than motor?
i think both will be same..
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%.
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 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!
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.
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.
A motor produces less mechanical energy than the energy it uses because the motor what?
Yes this is what we call efficiency of the motor. We give 100 but the motor in turn gives 40, so its efficiency is 40%
Are propane powered generators better than any other type of generators?
I think propane generator are better than any other type of generator because Propane and natural gas can save you time, money and aggravation that's why i think propane generator is better than the other generator.
Is a gas generator better than a gas turbine power generator?
A gas turbine power generator and a gas generator are quite similar, but they have their differences. For example, they are for things such as aircrafts which use them for mechanical energy. They are relatively safe to use, and it is better than a gas generator.
Why efficiency of transformer is higher than the efficiency of motor and generator?
Transformer is a electromagnetic stationary device which converts electrical energy from one level to another level by keepings its frequency constant. Whereas in motors or generator electrical energy is converted to mechanical energy and vice versa. Now when this conversion of energy is taking place noise and friction comes in existence due to which some loss of input energy takes place due to which energy output reduces and efficiency accordingly.
