Mag-Lev Bobin Motor---reed switch version with wireless energy transmission.ASF

This is the' Mag-Lev Bobin Motor' in a simple reed switch configuration. I use 'Maggie' to show wireless transmission of energy using the strong rotating magnet flux field created by the rotor. A small spinning neo ball magnet is in 'Maggie's mouth. I demonstrate how that energy can pass through water, a potted house plant , or a book.

Hi Lidmotor, been watching and replicating your stuff. (lots of fun). I do have a question reguarding the Reed Switch. I've got a vid uploaded using one in a motor, but I just use the North -South poles as I call them, the West-East I leave unattached. It can't tell if you're using them? The vid jumps a bit when you're explaining things. If so, could you explain. I'm still learning and want to add to what I know. Thank, EastcoastTinker.

@EastcoastTinker ---If you are talking about the other two leads on the reed switch-- they go th the coil in the reed switch. I have never used them. The Radio Shack reed switch that I used in this motor was built so that a current running through the reed switch coil would trigger the reed. I am not using the reed switch the way that it was intended---- but it works. Not all reed switches are like this one.

thanks for the video, very cool stuff.

I was wondering if you knew of a way to put a reed switch beside a roller blade wheel with magnets on it to work as a pulse motor, as opposed to facing the magnets ( like most pulse motors shown on youtube.) would a reed switch be able to work next to the coil? I know these things are not ideal for quick work, but do you think its doable?

[Lidmotor]

@LXXITobinator ---- The drive coil would have to face the magnets and then the reed switch would just have to be placed somewhere near the spinning magnets to fire the coil at the right time. That is an interesting idea ---- and doable! You might have just invented the first pulse motor powered rollerblade.

also if you could, would you explain how I would go about finding the right thing to add on, or could you explain the reason why the reed switches break. and how i could find the right diode or resistor to add on to the circuit, so i can make this darn thing spin. please oh please, I've been stuck on this for months.

hahaha, shhhh. so im trying to make an extremly simple pulse motor. im using HAA26 Magnetic Switch ( i think its supposed to go to window alarms) I am also trying out HAA27 Reed Switch For Alarm ( I think this one is for smoke detectors). I have some coils built, my strongest one is 21 gauge with a steel bolt as the core. i was wondering if you could tell me what else i need to add on, so i can prevent my reeds from breaking, and taking all the energy.

@kafr8413 --- That is a 25 ohm wire wound variable resistor (rheostat) that I got at Radio Shack. It is wired in series with the battery so I can control the speed. It also controls the amp draw at the same time. It is like adding a ballast resistor to the circuit.

@Lidmotor What does the potentiometer connect to?

[Lidmotor]

@kafr8413 -----The circuit on this one is as basic as it gets. The battery is connected to the small electromagnet via a reed switch. When the rotor magnet turns on the switch the electromagnet fires and spins the rotor. The hard part is finding where to put the reed switch and how to position the reed switch "control" magnet so that the switch only turns on when one pole of the N/S rotor magnet goes by.  The Led light is connected at the reed switch and captures the BEMF spike.

Another really nice project. What does the circuit look like? I see a potentiometer, but I could not see how it was hooked into circuit and if there were any other parts in the circuit. You usually have such nice paper drawings that let us know exactly what is in the circuit. If you could clue me in to the xircuit design, that would be really helpful. I am in the process of building your hall effect motor, but I like the simplicity of this one. Thanks,

Paul
