How does a mechanical ventilator that uses a square wave generator?

please send all the details or a website, and where the location of a circuit in a fan? Where applicable the Schmitt trigger? i really need it, if I may say all the details, please do,,

I did a question about a year ago on the use of a square wave inverter with a fan. This new issue needs more information about what is your goal. The Schmidt trigger could be used to convert sine waves to square waves at the level of the signal processing circuit. Not Sure how it adapts to your question. I can only respond by referring to the previous question ... A mechanical ventilator using a square wave generator could be a "Punkah" with a "square wave", who worked on the type of trap. Most likely any fan rotation efficient use of electric motors. Most electric fans using shaded pole motor which apparently did not work too well with the square-wave sources, and are also ineffective. By Therefore, the solutions are: 1) Use an engine that runs on a source of square wave (multipole induction motors of all types are not as relevant, but the reasonable adjustment tension or the addition of an appropriate amount of inductance range of suitable current rating can make it work. Some drivers have taken advantage of wall velocity inductors or transformers that can help save at full speed, so you could get an electrician to disconnect.) There are no guarantees. This does not leave much choice non-special "square wave" engines. 2) A better solution, use a sine-wave source for the engine. In his post a year ago you said you were not willing to change the investor. That's where the problem lies. It may be possible to modify the inverter if enough was known about it, but not worth the effort, and apparently not have the technical resources. A modern sine wave inverter could be cooler, smaller, lighter and more efficient. 3) Use a different engine and supply. In the previous post a year ago that you are using a 12V battery and inverter square wave to drive a fan, which apparently burned the fan. If you use 12V fan instead of the whole process more efficient. In fact, in the U.S. is not likely to be legislation prohibiting the induction and shaded pole motor for the fans (in cooling), and its replacement by engine speed controlled brushless DC, which are more efficient, saving large amounts of electricity throughout a country. If you are running from a 12V battery that is the best approach. So my advice to goodwill, however unintended, is to forget square waves, either get a new sine wave inverter, or a new fan that is 12V. I hope that helps.
