Exp 7: Coil Energization Timing

12/11/2004

As a follow up to John Bedini's comments about the timing of the energization of the coil (Yahoo! Groups Forum for Bedini SG Motor, message #443), I wired a diode across the driver coil of the SG Motor to serve as an indicator when the coil charges and discharges.

I snapped some pictures to view the magnet position as the coil is charged and discharged. Depending on the polarity of the diode, the charging or discharging of the coil is indicated by the lighting of a LED that is connected across the coil, as specified by Mr. Bedini.

The pictures are a little grainy because I had to set the camera shutter speed fast enough to eliminate blur from the spinning wheel so I could see exactly where the magnets were crossing the coil. The LED is a little hard to see when it is not lit, so I have included a blue circle around it in all the photos.

Charging of the Coil

The LED in this set of photos indicates charging of the coil by the 12V source battery. The diode is connected across the coil, with the cathode connected to the transistor collector side of the coil. The wheel is turning clockwise.

Note that as the magnet crosses over the coil core, the coil is charged which creates a magnetic South pole that attracts the magnetic North permanent magnet on the wheel. But if you look at the timing as the coil is energized, since the permanent magnet has just passed the coil, this atttaction should actually HINDER rotation of the wheel by creating a force opposite to the rotation of the wheel.

Disharging of the Coil

The LED in this set of photos indicates discharging of the coil. The diode is connected across the coil, with the anode connected to the transistor collector side of the coil. The discharge spike causes the anode of the diode to be more positive than the cathode, which causes it to glow. The wheel is turning clockwise.

Note that after the permanent magnet passes the coil core, the coil is discharged, which creates a magnetic North pole that attracts the scalar South pole located between the magnets on the wheel, as described by John Bedini at the bottom of his page at http://www.icehouse.net/john34/

The very interesting phenomenon here is that even though we have just seen that the initial charging of the coil actually works against the rotation of the wheel, the attraction to the scalar South pole (in between the permanent magnets) is the overriding force in this system and causes constant rotation of the wheel.
