When was wind power first used? - Renewable Energy

most blenders throttle the power by using different taps inside the motor winding themselfs ., the switch just selects what tap to use and applies power to that winding , just three windings can produce multi speeds if used in combinations sorry no easy fix for switchs other than to make sure theres no food down inside them , i use a good electrical contact spray (CRC) down in them to make sure

[You don't need a Soldering Station though. Use a 25 Watt soldering iron, or so. Rosin core solder, Rosin flux paste, etc ]

So, who is going to do the job?

83. denmark uses wind for over 25% of its power

Hi, a word of caution, use a 9volt battery instead of 12v to check the rotating field winding. The 12volts from a car battery or battery charger can burn out windings in a generator. I would say that your avr is pooched. There are 4 leads that go back to the windings in the generator from the AVR. Two of these are connected to the power output and two go to a separate winding in the generator. This is the exciter winding and this supplies power to the avr for the rotating field. The two to the power output are voltage reference only. If your generator has these exciter winding, you should check if you have voltage there with the 9 volts applied to the rotor. If you have voltage on the power output and not on the exciter, then the exciter is shot and your avr might not be. Try this first, if you could, could you take a picture of the windings at the back end of the generator, this will confirm for me what leads you have present.

No you don't have to wind this watch..it is a quartz movement powered by a battery...the only thing the crown is used for is resetting the time and date, you are probably thinking of a mechanical watch which is powered by a mainspring...:)

Most generators have several circuits incorporated within the windings. There are usually two 115v windings, one or two windings that produce power and sensing voltage for the regulator that supplies power to the armature (produces magnetic force) and sometimes a 12v winding to supply power to charge the battery. The two 115v windings power one 115v plug each and together power the 220v plug. Each outlet has a breaker and or ground fault. Since the 115v plugs are working indicates that the 220v plug must have an open/broken wire or faulty breaker. Easy to check, however you must open cover to wiring compartment and trace wires. Should be easy fix. You do not have to start engine to find broken wire. Use ohm meter instead. With engine off, Insert probes into 115v plug and obtain ohm reading. Then insert probes into second 115v plug and obtain similar reading. Look for same reading at the 220v plug (remember 2 circuits of 115v, ground and neutral). Good luck with your repair and email if you have other question.

Change the power steering fluid. Use the Mercon V tranny fluid (also used in the power steering system).

There was a day and time when generators were simple. There were no capacitors, regulators to control/adjust power to magnet or ground fault outlets. Winding getting hot indicates short, however could be bad capacitors. Rectifiers and capacitors must be removed from circuit to test properly. Here is a simple test that I use to find fault area. I use a small power supply (16v AC 1 amp like doorbell transformer) into the 110v outlet of generator. This should energize the armature magnet and actually produce voltage at commutator with brushes pulled off. You can slowly pull the starter rope to move the armature into a different positon the voltage will vary. If the ac windings are shorted there will be very little or no magnet. There is a seperate 110 v circuit at the 220v outlet to test (there are two 110v windings that make up the 220v outlet, one is also used for the 110v outlet). There is another winding that products voltage for the regulator that powers the magnet thru the brushes but I think that circuit is porbably working because of the heat in the windings. You might even have 110v power at the 220v outlet. As our parents told us over and over, be careful when working with electricity. Enjoy
