I suspect what you're thinking of is a machine that generates more than 100% of the power it uses, which does not exist (and is in fact impossible according to the conservation of energy).

What is the difference between synchronous motor vs induction motor and which one is better?
The big difference is that the synchronous motor's rotor can have a variable current applied to it through its field slip rings. Both types of motors have their own advantages. With a synchronous motor in the system, the systems power factor can be regulated.
What meter has its own power supply?
ohmmeter has it's own power supply
Can a motor drive a generator which can produce power more than the power used by the motor to drive the generator?
Claims about perpetual motion machines are always false because they ignore the inevitable losses of energy which must be overcome to make any machine operate so that it can do its intended work. Such losses mean that any machine, whether electrical or mechanical, must be supplied with more input power than it can convert into output power. In the case of electrical machines there are many reasons for energy losses: Bearing friction losses; "windage" losses caused by air having to be moved out of the way by spinning parts such as rotating armatures and cooling fans; magnetic hysteresis losses absorbed by eddy currents flowing in rotor armature and stator laminations; commutation losses in dc machines and slip ring losses in ac machines; excitation losses caused by the need to supply energy to the coils in the stator of a machine in order to magnetize it; general electrical resistance losses caused by the need to use energy to force electric currents to flow through the windings of any electrical machine. Whilst engineers have found ways to reduce each one of those types of loss to a minimum, it is still a fact of life that no electrical machine can be 100% efficient. In the case of a motor, it will always require more energy to be supplied to it than it can convert to mechanical power. In the case of a generator, it will always require more mechanical power to be supplied to it than it can generate as electricity. Some electrical machines have a power-conversion efficiency of up to 80% but most have efficiencies much less than that. If a motor and a generator were linked together to form a motor-generator set (the motor driving the generator driving the same motor) then, if both machines were as good as 80% efficient, that would mean the combined efficiency of the system of would only be .8 x .8 = .64 i.e. 64%. In other words, to keep the motor-generator set running, additional power equal to at least 36% of the motor-generator set system's own power would need to be supplied from an external source. Those facts make the set-up described in the answer to this question shown below pure nonsense. Period.
What is the difference machine and engine?
a engine creats it own power but a machine needs power to run
Can a 35 kw generator power a 35 kw elevator?
Only if it has it's own Power factor correction unit, Still a perfect power factor of 1 is hard to achieved. Common power factors are about 0.75 (it's like being 75% efficient, put in simple terms) Which is a little difficult, still the motor would be running at its limit. If this is to happen for short supervised conditions it could, but it would turn out to be unreliable if run continuously.
How do people in Antarctica get their source of power?
Research stations generate their own power, usually from gas-generated motors.
What horse power is 30lb. trolling motor?
I own a horse. He is powered by magnets.
Does each power window have its own motor?
Yes. There is a motor for each power window in a car. It's inside the door of course, attached directly to the window regulator mechanism.
Is there such a machine as a self running generator?
That sounds as if you want to build a machine that produces power without any power input. That is not possible - do some reading on the Law of Conservation of Energy. At least, it has not been achieved so far, so you won't find instructions on how to build it. If you want to invent one on your own, you are likely to fail - everything seems to indicate that the laws of nature don't allow this.
Can you use nuclear energy at home?
It is not practical for you to have your own nuclear power plant at home, however, it is perfectly practical for you to use electricity that has been generated in a nuclear power plant and then transmitted to your home through power lines.
Do the speakers that come with the Sony KLH40X1 monitor need their own power cord?
No, they will be connected directly into the monitor itself.
Can motor oil or transmission fluid be use in power steering pump?
NO ! -The power steering uses it's own type of fluid. Other types may damage seals.
How does a solar power car move at night time?
With energy charged into batteries during day time, or then with other means, motor. Solar power is not enough to power a car by it's own anyway.
Does a bar magnet exert a torque on itself due to its own magnetic field?
electric motors produce torque so in the sense yes
How do you disable one power sliding door on a Ford Windstar and keep one powered?
Each sliding door has their own motor. Disconnect the wiring to the little motor inside the door you want disabled.
Who gives the government their power?
The people give the government its powers. This is one of the foundational principles of the U.S. Constitution:Limited Government: Since the people give government its power, government itself is limited to the power given to it by them. In other words, the US government does not derive its power from itself. It must follow its own laws and it can only act using powers given to it by the people.
What would make a furnace blower stay on continuously?
broken vaginalsitila Usually a stuck switch in the motor itself. I would take the motor out (usually really easy job- Make sure that power to motor is off!!) Take it to your local motor shop and usually it will cost anywhere from 25 to 75 bucks to repair, as opposed to the 150 to 300 bucks for a repairman to do it. I used to own a laundromat and did this on a weekly basis. If the weather is to cold to have it out of service for long ask the motor shop if they could possibly fix it at once. For a few bucks more they'll probably do it.
