There are pulse motors listed at many websites. I feel that anyone interested, will know how the basic operation of these designs work and know how to build one.
I have decided that there is no use in describing the build of a pulse motor. They are all about the same. However one needs to know how to build and correctly wire pulse coils to be successful. This is indeed the heart of a successful build if you wish for a good return with additional potential gain. See below to look at drawing. There have been many descriptions of different coil builds. Some of them are claimed to be using exotic types of core material and seemly mysterious windings. Its just not that complicated. First, lets look at a small 10 foot in length piece of #19 size wire. This small length of wire holds the potential for voltage and current. The electrons that is in the wire are ready to be used. We simply must compress it. The same can be seen in a garden hose that we have filled full of water. The water is there ready to be compressed by applying pressure to one end of the hose. We apply pressure to the wire by connecting it to a voltage and current. We don't have to fill the wire with anything like we did with the garden hose. The electrons are always there in a relaxed postion. Let's say we apply a 100 DC volts to this wire slowly with the other end grounded. What happens? It will burn the wire up if enough current is used. What if we apply this 100 volts very fast in DC pulses? What about the time in between pulses? Anytime a coil is pulsed it applies pressure to the electrons already in the wire. This pushes out the electrons at the end of the wire FIRST to the load.(rather slowly I might add) If the pulse is strong and quick enough, electrons burst unseen from the wire at all sides. A kind of radiant energy of sorts. It will tingle your skin. When the coil is relaxed (in between pulses) any electrons lost rush back into the coil from the environment or vaccum. The coil will be replenished when it is in a relaxed state for any loss of electrons that it needs to orbit the atoms of the copper wire in the coil. Now, if we pulse the potential into the coil fast enough, a interesting event happens. In the relaxed state between a pulse, the coil is at a net loss of electrons momentarily. If we switch the coil to a capacitor at this time, this causes a "extended avalanche effect" to occur from the environment or vacuum into the coil, that spills over into the capacitor. This momentary avalanche time has been extended by using the capacitor. This rush to fill the coil void of electrons from the vacuum also causes a significant voltage rise. By looking at your wire tables and knowing the resistance of your wire at your chosen length with your voltage used, you can build a fine coil(s) to run a pulse motor and have it return plenty of potential. You must push the current in the wire of the coil towards the high end limit. But the faster you pulse the coil, this limit drops and performance increases. Heat is made in the coil from being pulsed, but cold electrons entering from the vacuum cool the coil instantly. One should have a cool or cold coil(s) to be operating efficiently. A cold coil simply means that a over abundance of vacuum electrons are being re-supplied to the coil and cap system while running than is actually being used. The capacitor acts as a extension of the partially drained coil of electrons, and the vacuum must re-supply the copper wire with a balance of electrons for the atoms in the wire. In doing so, the cap has been supplied with electrons also. We have simply tricked the vacuum into resupplying the coil and the capacitor . A soft iron core is all that is needed. Another trick imployed, is to wind a coil byfilar. Use the extra winding to dump potential from it into a cap. You can even wind the coil tri-filar and use the 3rd winding for a trigger to pulse the coil. One can then switch all of these coils to series connected (as a driver) in the relaxed state to increase potential. You can wire a extra coil in a series byfilar method and collect some of the E-field and radiant effects. This directs potential in the same direction as the pulse relaxation point. It seems that some magical event is happening in these coils by some folks. It is not. It is a natural event that happens if you wire your coils properly and switch them into a cap in the relaxed mode.
