OverUnity Lead Acid Battery Switching Circuit - Self Battery Charging

[SeaMonkey]

The overunity quacks like bedini and bearden have done more harm to the name of Tesla than anyone else.

They've certainly found it profitable to attach
Tesla's name to their marketing strategy and
product line.

Has anyone tried charging lead acid batteries in series with series wound universal type motors, such as used in most domestic products such as vacuum cleaners electric drills etc? I have an experimental charger using a vacuum cleaner motor run from a 240V to 90V (2 x 45V windings in series) toroidal transformer. The motor has a bridge rectifier at the input, so I have connected the battery on the DC side of the rectifier in series with the motor winding. Charging current is 0.5A with input power from the mains at approx.60W. Adjusting the torque on the shaft of the motor will increase the charging current, although I have found that with the motor running with no mechanical load, effectively charges 12V batteries up to 30A/hr capacity. The charge will condition the battery and leave its standing voltage high as with a Bedini type charger.

The simplest of these chargers consists of two things. A capacitor to the live wire of your mains and a diode bridge connected to the other end of the cap and neutral. The high voltage DC spikes charge/condition the battery and the cap limits the current. Very simple and very effective. The cap and bridge need to be appropriate for mains use.

Have you checked out Turion on the energetic forum. He's been experimenting with his 3 battery system using a scooter motor and other motors in series for years.

Yes, I've followed the EF thread from its beginning and is one of the reasons I posted my question, as I have found as Turion has, that there is a long term progressive improvement in the capacity of batteries placed in series with brushed motors. The net capacity improvement in repeated cycling within a 3BGS system is considerable. I have found that the universal series wound motor is superior to standard DC PM or pulsed PM motors by virtue of the constantly switching counter magnetic fields of the in-series armature and rotor windings. These alternating magnetic fields, together with the carbon brushes, produces some very high frequency and powerful transients in the nano-second time domain, which I believe create a very effective de-sulfation waveform with important relaxation times provided by the 50Hz sinusoidal grid frequency. I have found this method to be superior to the Bedini SG mechanical energiser methods. However, as with the Bedini energiser, care needs to be taken in limiting charging voltages but efficient cold charging is achieved with the minimum of charging current, although overall device electrical efficiency is poor.
