This device is built on a simple principle, the motor-generator, presented by the authors in 2015

The device has no power supply, buffer storage and switching keys
The device turns the transparent base consisting of a stator and a rotor, bifilar coils and magnets with alternate poles

Dear rakarskiy,

the devices in the videos which you cited in your posts above are all very good and deliver lots of free energy.

The world will be saved soon (but only if you are simple minded enough)!

Greetings, Conrad

As discussed above and (off topic) here , Infinity SAV have shown a motor generator . The salient features of the "1kW" model are as follows:

* the machine seems to have a stator with 50 coils arranged as 10 rows of 5 coils surrounding a a rotor with 55 magnets arranged as 11 rows of 5 magnets

* the coils appear to be air-core coils

* the machine is started without much force by turning the rotor axle between finger and thumb, and stopped again without much force by braking the rotor axle by pressing on it or gripping it between finger and thumb

* the control box is said to consist of an inverter and a micro computer controller board – perhaps something like an arduino

* there appears to be (or it is claimed that there is) no battery at all – not even a battery to run the control board

* early prototypes shown in Infinity SAV's Youtube video channel are structured as a simple stator with coils in a ring surrounding a rotor with magnets in a ring – the implication is that each row of coils in more complex later models is simply connected (whether in series or in parallel) so as to be equivalent to a single coil

* the rotor accelerates slowly and is said to reach about 6000 rpm – this and the ease with which it can be stopped suggests that the torque produced is not very great

Implications:
* the electromagnetic effect of turning the rotor produces the force that keeps the thing going

* the same coils are used to produce the physical force that keeps the rotor turning and the electrical output that drives the control board and is passed as input to the inverter

* the air-core coils will not of themselves produce any cogging effect of attraction to the magnets

Assumptions and hypotheses:
* the effect of moving a magnet near a coil is to create an EMF in the coil (electromagnetic induction)

* if that EMF causes an electrical current to flow in the coil, the effect is to produce a magnetic force that opposes the motion which produced the EMF (Lenz law)

* such an EMF cannot produce a current unless the coil is connected to a complete electrical circuit, and so (presumably) until it does produce such a current it will produce no magnetic field and no force that opposes the motion that gives rise to it

* in the case of a magnet approaching and passing a coil, the EMF will reach a maximum at the point when the magnet is closest to the coil – at Top Dead Center (TDC)

* if the EMF in the coil is allowed to drive a current only at and immediately after TDC, it will produce a magnetic force that opposes the motion (towards the coil) that gave rise to it

* the initial effect of turning the rotor is to produce an increasing EMF in those coils which are being approached by a magnet

* the purpose of the control board is to permit a current to flow in each coil only as each magnet reaches TDC with respect to that coil so as to produce a force that drives the magnet away from the coil

* the initial voltage and current requirements of the control board must be small enough for it to be capable of operating when the machine is manually started

* the current that is fed to the inverter is the current which produces magnetic fields that would have opposed the motion of magnets towards coils and which does in practice assist the motion of magnets away from coils

* the magnets and coils are all arranged in the same way – that is to say all the magnets and all the coils have the same polarity

* the generator produces a fluctuating direct current – it may be that it must be started by turning it in the direction that produces a positive voltage and that it only works when turning in that direction

* EMF is measured as voltage, and Tesla wrote of voltage as pressure. On that basis the approach of a magnet to a coil connected to an open circuit increases EMF pressure and closing the circuit at TDC is equivalent to combustion at TDC for a piston – but the increase of EMF pressure without current produces no immediate opposing force

Is there anything drastically wrong with this reasoning? Perhaps it doesn't take sufficient account of the EMF produced as the magnet is moving away from the magnet, although that will decrease to zero as the magnet reaches the midpoint between two magnets.
