Has anyone seen Lasersabers new motor runs on 1000uf cap

An easy test.........

Find a very small standard transformer (or one you have made yourself) and put the primary in series on one or the other side of the reed and see what you can get from the secondary. Then feed back the secondary to the holding cap. Maybe rectify the secondary with a germanium diode so the cap does not unload itself into the secondary. This would be a first trial in looping some energy back to the source capacitor without relying on the actual existing system.

If you want to get it working even harder use a second reed on top of the first reed and connect the transformer primary between the reeds so all three are in series (reed-transformer primary-reed) so that the primary gets completely disconnected from both sides when the reeds are open. See the effect.

When you apply any power source to a coiling system, does not matter how it is driven, if only one side of the coil is a breaking point, the other side of the coil is still permanently biased to the source polarity so the change in the coil is never complete. Is is only complete when both coil ends are completely disconnected that the coil re-biases itself to the only field left........to the Earth field, just  like your compass will bounce back to north (or south) when you remove a magnet. This may provide some added energy source but only if the coil is completely off the source from both sides. Sounds simplistic but I have found this to be very true.

The problem arises when such a scheme is tried with mosfets or transistors, the above condition can never be 100% true as it can be with a physical reed break. You can even try a second reed without a transformer and just put that second reed on the other side of your series coils and see the effect.

@Wattsup: I am always at a loss if someone "talks" a circuit instead of "drawing" it.

I would very much like to do your "easy test", but could not understand how to do it. Therefore I made a drawing of the circuit which you seem to talk about. (I have several standard transformers, some which I bought and some which I wound myself.)

Questions:

1) Could you please clarify the circuit for your "easy test", best by making a drawing of the circuit. (Could be a hand drawing which you photograph.)

2) Should the "holding cap" be pre-charged? (To what Voltage?) Should there be a power supply (e.g. a battery)?

3) How should one activate the Reed switches? (Must probably happen at a certain frequency, and this will need energy?)

4) Any idea whether the secondary of the "standard transformer" should have more windings than the primary or the other way round or an equal amount of turns?

I am not sure if you are interested in a meaningful discussion of your "easy test". If you are, a drawing of the circuit and some useful and understandable details will probably be the only way forward.

@conradelektro

Yes maybe I should have been more explicit that these tests can be done on existing EZ Spin Motors.

I have done a drawing below to show you how to try it.

You can test it by precharging your cap to your regular voltage that you have used to run the motor. Or, you can always run it with your battery to start with and then remove the battery.

The two reeds can be positioned at the same location or at two different locations as long as they are activated at the same time by the rotor magnets. Then you can always play around with that position to see if a slight offset in timing will be better or not.

The transformer should be very small, about the size of your thumb. Primary to secondary ration of turns is really not important at this stage. Most transformers are step down type so you can always try it by using the secondary between the reeds and the primary going to the cap.

The other option I mention in the drawing is simply not using a transformer but having two reeds, one before and one after the 6 series coils. This is the real method to release the energy in the coils while the reeds are both open. If you scope this one I expect the waveform should rise off the screen

These are just low cost test ideas that I should be doing myself if I had an EZ motor (hint-hint). lol

@gyulsan

Yes I had mentioned the diode as well but forgot to add it to the drawing. It is added now.

Hi wattsup,

May I mention that the DC resistance of the secondary coil of the transformer you connect in parallel with the 1000 uF capacitor may discharge it severly?  Probably a diode in series with the secondary helps prevent discharging.

The double Reed switch dilemma:

A) Opening two Reed switches: A reed switch before the primary and one after the primary of a transformer (or coils) will never open at exactly the same time. So, whatever happens will happen while one Reed switch is still on. One can adjust which one will open first.

B) Closing two Reed switches: It is similar when the Reed switch before and the Reed switch after the primary (or coils) close, but in this case the two Reed switches act like a logical AND. So, whatever happens will happen at the moment the second Reed switch closes as well. One can adjust which one will close first (but it does not matter which one closes first).

Conclusion:

Opening or closing two Reed switches at the same time is practically not possible. Electricity moves at the speed of light, the mechanical action of a Reed switch is always too slow.

Even with two Reed switches in a single glass tube, one will open/close first (depending on how the magnet approaches the glass tube and on the physical properties of the two switches, one will bend easier than the other).
