MCharley's Replication of John Bedini's Simplified 'School Girl' Motor and Battery Energizer
Replication of John Bedini Motor accomplished November 28, 2004.
First Motor: Four magnets doubled: .75" diameter on top of .5".
Rotor diameter: 2.5".
Weight balance diameter: 2.5".
Motor height: 3.25"
Motor length: 3.25".
Coil one length: 2.25".
Coil diameter: .75".
Coil one configuration. Difference: Core made of 3" standard round head threaded screw. Bi-fil #23 magnet wire wound counter clockwise to magnet face.
Trouble-shooting to get working
Initial coil as described did not give auto rotation. Tested coil for shorts, Ok. Tested transistor for voltage C-E out terminals,Ok. Tested for voltage at B input of transitor, while manually rotating wheel, No voltage. Measured Ohm of B wire, resistance not enough to generate voltage needed to fire transistor. Adjusted length of wire.
Batteries: First test of motor used standard 9 -volt battery. Motor auto rotated, struggling to stay alive.
Adjusted ohm resister. Still struggling.
Switched to 9-volt Ni-Cad remote control car battery.
- Restarted manually. (What a sight to see)! Birth of B-motor.
- Adjusting resistor changed the rpm from none to super fast. Sorry no tach to confirm speed.
Motor has a steady hum. All components coil, transistor,etc., are running normal room temp to cool. No heat at all.
First motor was built to confirm that John Bedini Motor is valid and verifiable. It is.
Second motor built 3 December, 2004.
Rotor diameter 4.75".
The second motor coil built has the charging back end.
Running near silent. Slight hum. Been running all day Saturday 4 December to present writing on 7 December, 2004. Using Second coil from first motor. Seven 1.5 D-cell batteries in series. Have recharged the earlier nine volt batteries. In addition,Charge four 1.2v double AA batteries. Removed charging batteries.
Attached charging end positve negative wires to main batteries of motor.
Start main battery charge: 8.64 volts.
6 hours later, battery voltage at 8.12 volts.
Motor is "self feeding" and expending its amps.
Have adjusted resistor to special place where resonance happens. Can hear light squelching noise and see battery voltage increasing in increments of 1 to 2 hundreds of an amp at this tuning spot. Current rotor evidently not large enough to carry the forward momentum to keep the resonance continual for this test cycle.
Batteries are now at 8.32volts.
Charging current\battery usage voltage set at 8.15 volts. Will leave at this setting to see what happens.
Increasing rpm of motor and letting it coast at the "just right spot" does increase the battery charge. As easily as it charges itself it also can expend its charge.
Decided to increase to full battery discharge to see what happens.
Second Coil created to use for battery charging testing. Motor "one" was used for the simple test. Battery source used are 8 1.5v D-cells in series. Motor used to charge 6 nine volt batteries to full charge in the course of three days. Motor ran from eleven am, Monday 29 November, 2004 to Wednsday morning Nine twenty am, 1 December, 2004.
Monday - main battery voltage loaded read 9.98 volts at start. Wednsday - main battery voltage end of charging cycle read 9.26 volts.
- Nine volt battery One Start charge: 8.85 volts End charge: 10.30 volts.
- Battery Two S-charge: 8.10 volts E-charge: 10.10 volts.
- Battery Three S-charge: 7.23 volts E-charge: 9.69 volts.
- Battery Four S-charge: 8.34 volts E-charge: 10.85 volts.
- Battery Five S-charge: 8.28 volts E-charge: 11.75 volts.
- Battery Six S-charge: 6.20 volts E-charge: 9.81 volts.
Motor stopped at end of battery six charge, 9:20 am (Wed).
Motor restarted using same main charge batteries.
Battery Six final charge ended up to be 10.73 volts.
Batteries were remeasured to see final charge amount in each battery on day three.
Volt readings are from batteries One through Six. 1=8.78 volts, 9.04v, 8.79v, 9.16v, 11.75v, and 6=10.73 volts.
The ohm resister was readjusted for optimal tuning of charge and discharge of batteries. In addition to Bedini Motor components, a new "charging circuit", designed by me was used to charge these batteries.
Pictures to be posted soon. First pic is first motor first coil. Third pic is second motor using second coil.
Second experiment done with three nine volt batteries joined together per the positive battery charging technic.
I now continue with the experiment of the three batteries as comprehended by the Positive Battery Charging Technic. Two batteries were placed end to end in the Negative Positive, Negative Positive position. Positive and Negative were joined together between the two batteries. Total Two parallel battery voltage reading at 18.57 volts. The Third battery was place next to the First battery with their Negative terminals joined together. Third battery reading was 8.71 volts prior to placement. This arrangements gives to two positive terminals for charging points. (Danger)!? Use voltmeter to check voltages. Important, the readings will come out that one of the positive terminals will read as a negative terminal. Hook to charging circuit in normal fashion.
Twelve hour charging cycle accomplished.
Battery Three Start voltage: 8.71v, End voltage: 8.35v.
Batteries One-Two Start voltage: 18.57v, End voltage: 20.01v.
Three batteries with positive to positive Start voltage: 9.87v, End voltage 12.03v. B
atteries seperate voltages checked. Bat 1: 8.41v. Bat 2: 9.60 v. Bat 3: 10.08 volts.
Experiment done with extreme caution. Small nine volt batteries used. Do not know how larger volt amp hr batteries will behave?
All credit goes to Mr. Bedini and others who have committed their time, energies and have endured the years waiting for the full fruitation of their labors.
