Motor speed rise with load
Simple demo of the effect being possible and automatic. There’s a lot of talk at the moment, within the RomeroUK/Muller motor discussions, about the speed of the rotor actually increasing after a load is put on the system. A recent build of my own, the FanGen, displays that behaviour…not that i’ve worked out exactly why, just that it does. The FanGen is a 12V PC fan, running with the original drive circuit, from a 12V supply. The idea was to remove the running part from BEMF energy collection – the collapsing of the energy field of a coil when it is switched off or short circuited. A Hall sensor is fitted just left of the coil and shorts the coil just before a magnet passes by. The result, is a huge spike of energy, which with no load applied to the coil is sufficient to light a neon bulb (90V AC required for neon). In this demo a 12V battery is being charged – when a 12V bulb is used as the extra load, the fan rotor gains speed. While the drive electronics are not being interfered with, the magnets and field effects may well be. Less forces from the magnet to coil relationship = more speed that the rotor is able to achieve. That’s my theory.
