One really needs the manufacturers part number to get that information. If the dataplate is gone, you can ohm out the windings, and through the process of elimination determine the  proper connections. You might want to check out the stepper motor seciton at CNC zone.\nhttp://www.cnczone.com/forums/forumdisplay.php?f=193

Are you looking for composites in biomedical fields?\n\nAnything used in biomedial applications has to produce as few allergic reactions as possible.  So some metals are out, since some people are allergic to metals.  Biomed pieces also have to be light, since it wouldn't help to have a prosthetic arm that weighs more than the rest of your body.\n\nSo composite materials are those that require several components, sometimes arranged in layers  Think for instance of carbon fiber.  It is made of several sheets that are soaked in pitch and baked to achieve a solid piece.   It is used in prosthetic limbs, and it is a composite that is non-metallic.  Carbon fiber is light, strong, and can be made into many shapes.\n\nHope this helps.

The generator consists mainly of a coil of wire wound over an iron core.This wire is connected to an external circuit where the current produced is either stored in capacitors or used to run a particular device. When the axle of the wire is rotated, magnetic flux linked with the wire changes and hence, according to Faraday's law, an electomotive force(emf) is induced in the wire as it is placed in between magnets having different polarities. Slip rings are present to allow the flow of the alternating current produced into an external circuit.

This happened so long ago to suggest there should have been a standard is funny.  The frequency has more to do with the speed of the turbine and the number of poles on the generator.  Early US generation was actually 25Hz.  The larger the frequency the smaller the transformers and motors are, but also the higher the losses (inductive reactance is proportional to frequency).  So there isn't necessarily a perfect frequency to use.

The LC Fiber Connector used on the LC Patch Cords has a latch mechanism that allows the connector to be easily engaged and disengaged. This latch also prevents the plug from snagging when jumper cables are being routed. A small-form-factor (SFF) design based on a proven 1.25-mm ceramic ferrule with a \n \n \nfamiliar latching mechanism of a RJ-45 modular plug and jack. A duplex configuration offers a high-density fiber-to-fiber pitch with the lowest insertion loss among SFF connectors at 0.1 dB average. A single-mode and multimode product range LC Patch Cord utilizes the smaller 1.6 mm cordage. The duplex cordage is 1.6 mm by 3.6 mm in a figure-8 design that has two single fiber cords joined together with a web.

I cannot immediately give you a perfect answer BUT if you contact one of the manufacturers of wind turbines (a 5 second task with google) then they will almost certainly be happy to give you a LITTLE information from their technical guys.\n\nIncidentally the same works in reverse - which is why aircraft with props only have two blades.\n\nWork was done to find that ONE blade would be best if it could be balanced - hence some very curious looking "helical-style" blades on some BIG experiments wind turbines.\n\nThis is also conditional on a good design for the blades AND a given wind speed. For example, a twin bladed turbine CAN have difficulty starting in VERY low wind levles - when a multi-blade WOULD work. Yet once upto speed, the twin blade or helical blade would be most efficient.

While any non-zero rotational velocity will produce a varying voltage, there are two considerations to keep in mind.\n\nFirst, at low rotation rates, the amplitude of the voltage produced will be tiny, and so the system will not be producing much useful power.\n\nMore importantly, if the turbine is to be connected to a local power generation grid, it must generate power at exactly the desired frequency for the grid, and must deliver that power in phase (it's bad if your generator pulls when all the other generators in the system are pushing, because in the absence of protection systems your generator will suddenly receive a huge current injection from all the other generators).\n\nTypically a power generator isn't a simple winding coil, but three coils generating voltages 120 degrees out of phase, but each coil is still generating a voltage at the frequency compatible with the power generation grid.

P = EI (Power equals voltage E times current I)\n\nMany electrical properties can be explained as analogous to water flow.  For example, a transformer "transforms" high voltage and low current into low voltage and high current, keeping the power constant (except for minor losses) at full load.\n\nThis would be equivalent to a high pressure water pump supplying low water flow to the primary winding and taking out high water flow at low pressure from the secondary winding to drive a low pressure water turbine.\n\nYou could represent the transformer core as a hollow square of wood or even thick cardboard.  On one side wrap say ten turns of thin clear plastic tube around the core to represent the primary (first) winding.  On the other side wrap say five turns of larger diameter plastic tube around the core to represent the secondary (second) winding.  Fill the primary tubing with water and red food coloring to represent "hot" high voltage and the secondary tubing with water and blue food coloring to represent "cooler" low voltage.\n\nThe explanation of course is that the high voltage primary winding will have more windings of thin tube (similar to more thinner copper wire windings) because the current will be less than in the secondary winding.\n\nThere will be less windings for the secondary coil using larger tubing because the current will be higher at low pressure.\n\nSupply the secondary tube with a shut off valve (or clip) to represent the fact that there will be no current unless the circuit is open.  In the formula, if current is zero power is also zero (on both sides of the transformer).\n\nYou can represent the pump and turbine with pictures (or drawings) of same but it would not be impossible to rig an actual pump and turbine, just not necessary to "see" what is happening.\n\nThe turbine can use up more and more power until the maximum power of the primary winding is reached but not more.  The magnet of the core will be "saturated at full power."\n\nThe rest is explaining magnetic flux in the core and how it is produced by the primary winding and cuts through the wires of the secondary to produce voltage and current if there is a load.  Each winding of a coil adds to the effect.  A transformer with equal primary and secondary windings would have the same voltage and current under load.  I believe that the phase would shift 180 degrees because of lead/lag.   Good luck.

Actually it's a question in physics. I will try to explain it anyway:\nassume we have two windings w1 and w2 with  n1 rounds and n2 rounds respectively. If an A.C. voltage of V1 is connected to w1 then a voltage V2 will be induced in w2, satisfying the following equation:\nV1/V2=n1/n2 and for currents we have: I1/I2=n2/n1\nand it doesnt convert ac to dc to do so we should use a rectifier such as bridge rectifier etc

here is an excerpt from the following source:\n\nhttp://chemistry.about.com/b/a/000855.htm?terms=spider+silk\n\n\nHollow nanofibers spun from a carbon/polymer composite are tougher than Kevlar, steel, or spider silk. 'Toughness' is a term used to describe the ability of a substance to absorb mechanical energy before breaking. Go to Science News to read their article on the nanotubes.

This is a magnetic flywheel.  The spinning magnets will induce a voltage across the coil of wire.  If you draw current from the wire, that current will induce a magnetic field which will exert a torque on the magnets, slowing them down.  The total electrical energy you can get out of the system will never exceed the initial kinetic energy of the rotating magnets.\n\nThe thing slowing down the magnets is not friction, it's an electromagnetic force, and even if you eliminate friction completely, the magnetic torque will spin down your magnets quite handily as soon as you start extracting energy from the system.

I assume you mean "fiber reinforced plastics" (FRP) rather than fiberglass insulation batting.  There are a variety of processes for FRP manufacturing, but your basic ingredients are a resin and the reinforcing fibers.  Most of the resins (plastic) used are thermoset resins that use an catalyst (activator) to cause the resin to set.  In some cases the fibers are laid into or wound on a mold prior to application of the resin/catalyst.  Other processes use a "gun" to chop the fibers and apply them to the mold at the same time as the resin/catalyst.
