Oscillating sine wave LC tank magnet motor.

Threshold speed is critical for the reversal of the "Lenz Acceleration" efficiency curve. The inefficiency of the iron cores reverses itself at a sufficiently high R.P.M. One needs to study JLN's very high quality test videos to understand this. Compare JLN's test bed to the "Trash Ball of Christmas Ornament's".

@MarkE,

Quote from MarkE:

"The JLN scheme with the soft iron rod just looks like it saps power and efficiency to me.  If you have measurements that show a gain, I'd like to see them".


I'm not here to spoon feed you. Here's a link to JLN's web site. Type "regenerative acceleration" into the site's search engine, and review the videos.

JLN doesn't have measurements that show OU from that device.

The faster one oscillates a field near conductive material such as iron, the greater the induction heating losses that result.

@MarkE,


I asked that you review JLN's videos. You'll find his calorimetric testing shows that there's an opposite cooling effect over the Threshold. Something I noticed myself and commented on repeatedly over the years.


The insertion of the ferrite output cores would alter the inductance of the air core power coils somewhat, but that would tend to increase the efficiency. The variable oscillator can tune to the new resonant frequency. Apparently you haven't studied JLN's tiny series of excellent videos enough.

Synchro1 over the years I have become pretty framiliar with JLN's work.  He does not get surplus energy out of the arrangements we are discussing, (or any other experiments that he has conducted either).  Eddy currents are a real thing that cause real loss that increases with frequency.  JLN like a lot of other people has conducted experiments where one really inefficient mechanism is replaced by another less inefficient mechanism.  Thes particular experiments are no different.
