The "Ossie motor" by JL Naudin

The "Ossie motor" has been designed by an Australian friend Ossie Callanan fascinated by free energy researches. Ossie has recently sent and shared with me his new innovative design of this very high efficiency pulse motor. Ossie has also published for free and for the benefit of all through the internet on the overunity forums. The "Ossie motor" is able to run in closed loop during a lot of days and self-charge its own battery, its efficiency is very close to 100% and may be more...
You will find, below, the full construction details and diagram of the "Ossie motor".

The "Ossie motor" uses four AIR CORE coils and four NdFeB magnets mounted on a old mechanic from a computer fan.
The blades of the computer fan have been removed and the Neodymium magnets have been fixed with cyanoacrylate glue on the rotor.
Magnets specifications:
4 NdFeB magnets (Bremag 27) of 27 MGoe (208 kJ/m3) polarisation N outward.
Magnet size: diameter 22 mm, 10 mm thick
Coils specifications:
Four AIR CORE coils: Monacor LSIP 180
Inductance : 1.8 mH, Rdc: 0.55 ohm
Outer diameter: 70 mm, Inner diameter: 23 mm, thickness: 30 mm
Rotor specifications:
Old rotor mechanics from a computer fan, diameter = 52 mm
less than 2mm gap beetwen the rotor and the air core coils
Battery: NiMh battery from 1.2 to 6V can be used

In the closed loop test, I have used 4 NiMh cells (4x 1.2v connected in parallel),
Each cell capacity is 2650 mAh, this gives a total of 10600 mAh,
With this battery, the "Ossie motor" is able to self run for a very long time...
Below, the additional components required to build the "Ossie motor"

The BAT 42 is a very low turn on voltage and fast switching Schottky diode (
here, the datasheet)
Such a diode is required to reduce voltage drop during the charge of the battery by the motor.

The ceramic resistor 2.2 ohms is used to reduce the current flow in the coils
Above, the voltage across the coils: Timing is very important here, the 1st ILS switch is used to set the start of the pulse, the 2nd ILS switch is used to set the end of the pulse. Shorter the pulse is, better the efficiency is... The CEMF induced in the air coils by the strong Neodymium magnets is used here to charge the battery, so the motor is able to self-charge its own battery through the fast switching and low voltage drop Schottky diodes.

Above, you will find the voltage recorded across the battery in closed loop mode.
To reduce the duration of the battery voltage measurement, I have used a 4.8V NiMh battery (2800 mAh) (photo below),

I have now confirmed that to make a self runner that WILL run INDEFINITELY on the same battery, you must make your input pulse amplitude and pulse width sit inside the generator pulse such that it is virtually masked and unnoticeable!!! But the motor will STILL RUN!!!
- My motor and any replication motor can run indefinitely once tuned correctly and the coils have enough turns for the magnet strength and RPM such that the generator voltage is equal to the battery voltage.

- Whether you pulse in attraction or repulsion mode does not matter. It works the same.

- Please see my latest video below. Note the waveform across the coils for tuning. You need to make sure the input pulse voltage DOES NOT exceed the generator pulse voltage. You need to get your pulse width to fit almost exactly neatly inside the top of the generator pulse such that you can't even make out the input pulse as it is masked inside the generator pulse. Don't worry, the motor will still run when you do this as long as the input pulse width is wide enough but still within the generator pulse.

- I am reluctant to say that you can get the battery to charge as well, even though I am doing this also, because it is not easy so until I can work out a simple enough arrangement and circuit for others to replicate a battery charging effect also, I will just say that you can run this motor indefinitely on the same battery with what I have presented so far, fairly easily!
I feel this is a huge breakthrough in the understanding of how to tune this motor.

Hopefully this will make it a bit easier for others to replicate...


UPDATE v1.2 :
According to the Ossie's comments above, I have reduced significantly the pulse current by adding two 22 ohms resistors in series with the ILS reed switches and removed the previous 2.2 ohms in serie with the coil. So, the coils are connected directly to the battery through the Schottky diodes and thus the charging effect is better while the current spent for the pulse is significantly reduced.... See the new diagram v1.2 below :
Woow... The result is indeniable, the "Ossie motor" still turns at full speed and continue to produce a strong CEMF to contribute to the charge of the battery while shape of the pulse begins insignificant compared of the level of the CEMF. Only the start and the end of pulse spikes can be observed... See the scope picture below :

In this case the "Ossie motor" is able to run itself for a lot of hours...
Below the video of the "Ossie motor" v1.2 in action :

After the long week test run in closed loop,
the NiMh battery has been recharged and 3028 mA have been reloaded.
So, it is interesting to notice that during this long test run, the "Ossie motor" v1.2 has needed less than 20 mA per hour to run at full speed... If we take in account the self discharge, non negligible, of the NiMh battery and the mechanical losses, we can say that this motor is very efficient...
Below, a new version v1.3 for an improved charge of the battery with a full Schottky diodes rectifier (Thanks to futuristic). With this new version 1.3, equiped with a full bridge schottky rectifier, the improvement of the charge of the battery will give us some very promising results...
The "Ossie motor" is a very efficient pulse motor, not yet OU, but with a COP very close to 1...
