How does a PT6 engine work?
There are three parts to the PT6 engine. First is the compressor section. It's like any other turbine engine. Next is the "free power turbine." You have seen the little pinwheels kids like--you blow on them and they spin. Well, this is a pinwheel for grown-ups: there's a fan on the end of the compressor section's shaft. It blows air against a second turbine that's attached to the next section, which is the gearbox. When the second turbine spins... the gears and shafts in the gearbox turn and make the engine's propeller rotate. The PT6 is an unusual engine in that it's "in backwards"--the intake end of the engine, which in most engines points toward the nose of the plane, points toward the tail on a plane with a PT6 in it. PT6 engines are very versatile and have been used for a lot of things. Someone even tried running a locomotive on one--it worked fine but railroad mechanics would need to be retrained to work on jet engines, so the experiment never got past the trial stage.
What is the difference between an electric motor and an electric generator?
HOW ARE ELECTRIC GENERATORS DIFFERENT THAN MOTORS? There is no fundamental difference between an electric motor and an electric generator or dynamo. In normal use, all motors behave as generators, and all generators behave as motors. DC Motors act like generators because they use less electrical energy when allowed to spin fast. DC generators act like motors because they become easier to spin when less electrical energy is drawn from their terminals. For example, connect two small DC magnet motors together. Then if you spin the shaft of the first motor, the second motor's shaft will start spinning too. One acts as a DC generator, and the other acts as a DC motor. Or, spin the second one's shaft, and the first one will start spinning. Another example: If you connect a small DC motor to a small battery, then an electric current will appear in the motor's coils, and the motor starts spinning. But if you spin the motor's shaft slightly faster than the normal speed, the direction of current in the circuit will reverse, and the battery starts taking in energy from the motor. The motor has become a generator, and it's recharging the battery. Here's a good way to visualize what's happening. Imagine two pulleys connected by a rubber drive-belt. If you spin the first pulley, it pumps the belt into motion, and the second pulley starts spinning. Ask yourself this: which one is the generator? Answer: both and neither. A pulley is just a pulley. Of course we can *force* a pulley to behave like a motor: let the pulley rub against a moving belt, and the pulley will start spinning. Or we can turn it into a generator: turn the pulley, and the belt will be forced to move. In electric circuits the wires contain a circular "belt" made of electric charges (the electron-sea within the metal.) And as with the pulleys, the "belt" inside an electric circuit will slowly move along just like a leather belt. (You cannot see individual electrons, so when crowds of electrons start moving inside the wires, you cannot see any motion.) Or pretend that you have two water pumps which are connected together with hoses. Fill the pumps and the hoses with water. Now, when you turn the first pump, the pressure inside the "water circuit" drives the second pump into motion. This shows you that all pumps are motors, and all motors are pumps. It just depends on for which purpose they're employed. COILS AND MAGNETS Here's a simple electrical experiment which shows what's happening with motors and generators. Get two coils of wire wrapped on hollow plastic spools. Connect their wires together. Get two powerful bar-magnets and place the end of each magnet inside each spool. Now if you jerk one magnet suddenly, the other magnet will feel a kick. What happened? By suddenly yanking the first magnet, the first coil created a voltage because of "Lenz-Law Induction." This voltage caused all the charge in both coils to begin moving along. That created a magnetic field in the second coil, which gave the second magnet a kick. Motors and generators are based on this phenomenon. AC MOTORS AS GENERATORS But what about AC motors? And what about DC motors which use a "field coil" but no permanent magnets? If you spin either of these, a voltmeter will show no voltage. It's because you aren't using them correctly. To act as a generator, an AC motor needs to be connected to a power grid or to a large-value capacitor. And a DC field motor needs to be connected correctly (series-wound motors must be shorted, while parallel-wound motors must be left open.) And finally, these types of motors can only generate a voltage/current if they're spinning FAST. It takes awhile for tiny initial currents to build up. When no permanent magnets are present, and all you have are moving coils and pieces of metal, it takes current to make current. The current and voltage gradually build up because of a positive-feedback process, and this process doesn't kick in until the motor's shaft is turning faster than a certain speed. MODERN MOTORS DISCOVERED ACCIDENTALLY The modern DC motor was not designed as a motor. In the middle 1800s, inventor Zenobe Gramme was trying to build an electric generator which gave a very smooth output voltage. He did this by using many coils with overlapped fields. Because of it's smooth DC output, such a generator could replace large banks of batteries being used at the time. In 1873 one of his assistants accidentally connected two of his generators together. The first generator was being spun by a steam engine, and the second one unexpectedly started spinning like a motor. The "Gramme Machine" has been used ever since, under the name "DC motor" or "DC generator."
What exactly is a tied gyro and how do they 'tie' it?
It is a horizontal gyroscope employing a 2 degree-of-freedom gyroscope with its spin axis aligned with the earth's magnetic meridian
Which way should a fan spin?
It depends on how the fan blades are angled. If there angled right at 45 degrees then it should spin clockwise but if angled left 45 degrees anticlockwise. Please improve this answer since i am 11.
Should a ac compressor spin easily?
no
Does water pump pulley move on 1999 chrysler cirrus?
It should spin freely, but not wobble.It should spin freely, but not wobble.
Why would a washing machine not spin out all of the water?
The bolt that holds the pulley to the drive gear for wash and spin may have come loose and the pulley is free-spinning or the gear has come loose from the shaft. At worst, the gear is broken.
What would cause a very loud whine in a 1998 Taurus?
Since I don't know what kind of whine your talking about ill name a few things that could cause it. there can be a couple things to cause whining under the hood. most common I have found is the power steering pump, either its low on fluid or its just worn out. you can usually tell its the pump by letting the car idle and turn the steering wheel side to side. the noise will change. could be a pulley, usually to check that would be to remove the belt (Serpentine) or belts(regular V-Belts) and spin the pulleys. hand spin each pulley, they should spin free, smooth, and quiet(except for the crankshaft). You should not be able to wiggle the pulley side to side. it should be taught. Usually though, a pulley will squeak, chirp, or make a growling noise. if you have a bad pulley, the only fix for that is to replace the pulley or its bearings. this can include water pump, idler pulley, tensioner, alternator, power steering, air conditioning compressor. could also be something as simple as something rubbing on a pulley or belt but i highly doubt it. hopefully this solves your problem.

Can you bypass the air compressor pulley on 2003 ford f 150 4.6 L?
You mean the air conditioning compressor? It can be done, but you'll need to find a belt which will work for that application... it's a bit of a crap shoot, and I suggest you find some F150 forums to find out which belt you can do this with and how to route it, although there really is no need to bypass it.. as long as you have the AC turned off, the compressor clutch won't engage, and the pulley will spin freely.
Examples of the fixed pulley?
A pulley that doesn't spin. Like the ones they had 10,000 years ago
Chevy Malibu 99 water pump pulley supposed to spin?
yes it is!! it must be froze up, the belt should turn this pulley to make the water pump work so coolant circulates in engine.
Is the cylinder supposed to free spin with the hammer down on an early H and R 922 revolver with the octagon barrel or does it need repairing?
No. it should not spin free. have it checked out by a gunsmith....................
Is your alternator broken when the pulley is frozen?
if it doesn't spin at all, yes it is broken if it doesn't spin at all, yes it is broken
Should the idler pulley turn freely when its replaced on a 94 ford ranger without the engine running?
yes. it is a dummy pulley, its purpuse is to kep the belt in place and tight. ==answer no it should not turn at all if installed and belt is on it if belt is not in place, yes it will spin freely
Why won't my air conditioning compressor on my 1999 Lumina not spin free?
sounds like elec problem, meaning power engaged and is in "on" mode or bearing shot if you mean by hand
What kind of simple machine is a spin cast reel?
wheel and axle
