• Bedini Motors Play all

    Employing the latest 'Energy Harvesting' technologies, pulse conditioning circuitry and 'burst' mode operation, these Bedini Motors provide the ultimate efficiency and performance using extremely low voltage sources.

    A small array of solar cells powers the motors from available ambient light. The motors charge a super-capacitor to provide power during darkness; running the motor for days in the absence of light.

    These motors average 2,000 RPM, accelerating to 10,000 RPM in 'Turbo Mode'. Modifications to the rotors, to minimize air resistance, have permitted speeds in excess of 80,000 RPM, powered by 1 volt at 1 mA.

    The motors operate nominally at 1 volt at 400µA. At lower voltages, the motors switch to 'burst' mode and will continue to run at 0.6 volts whilst consuming less than 100µA.

    These motors will run continuously for years under the right lighting conditions.

    Perpetual motion ? Almost !

  • Battery Desulphation Play all

    Desulphation is the process of reversing the process of sulphation that occurs to a lead-acid battery over time. Desulphation restores, at least partially, the ability of the battery to hold a charge over the life of the battery originally caused by sulphation). Sulphation is the formation of large non-conductive crystals of lead(II) sulphate (PbSO4) on the battery plates. Eventually so much of the battery plate area is unable to supply current that the battery capacity is greatly reduced.

    Desulphation is an attempt to reverse sulphation. Desulphation is achieved by high current pulses produced between the terminals of the battery. This technique, also called pulse conditioning, breaks down the sulphate crystals that are formed on the battery plates.

    Sulphation is a natural process that occurs in all lead acid batteries, but can occur significantly faster if placed in the wrong combination of temperature, poor charging technique, protracted battery misuse.
