Hi all,

Some news from the lab, the Newman V2.0 is undergoing tests and it looks like I will get the speed I need but I'll have to setup carbon brushes and a good recovery circuit as the bemf are saturating the spark gap at over 150V. I may need to mod the commutator according to my needs.

On the other front, my alternator is coming along well, I molded the coils in the frame and just need to connect the bifilar and output wires. The rotors are all done and just need the magnets to be set in. It's starting to look good and assembly should be this week.

Take care,

Michel

Re Hi all,

The rotors are almost ready, I just set the magnets and I might paint the steel discs tomorrow for a nicer finish.

Take care all,

Michel


EDIT: The pictures are before and after the magnets were installed. Each one of those have a 86.7 lb pull so I will be careful not to pinch a finger or two. Work safely as always.

Hi Michel,
looks very nice your alternator and Newman machine.
Keep up the good work.

The trick with the Newman motors is to
use many battery cells, best Lead-ACID or NiMH in series to get the voltage
very high , so the current draw from the batteries is very low.


So, if you want to have a Newman motor, say with 10 Watts mechanical power output,
you need to get around 100 mA current draw and 100 Volts battery supply voltage.

100 mA is still a bit too high for the current draw, so if you work cautiously and
know how to handle High Voltage DC system, you can also go to 1000 Volts
battery supply and 10 mA input current.

But if you want to use a Newman motor for an electroscooter (as I want to build it soon)
or for another vehicle, you should better stay around 100 Volts for safety, although 100 Volts
DC can also already kill you...

As the Newman motor produces free electrons at the sparking commutator by oxidizing
the graphite electrode, these free charges will recharge your battery within the BackSpike
and the batteries will last much longer, as if you had drawn 10 Watts DC current from your
batteries.

So the overunity effect will come into the batteries and the Newman motor can be operated much longer
on the same battery charge energy than a normal DC motor operate.

So using a Newman type motor will finally make electrical vehicals
very practical as the recharge interval will be greatly reduced.

So driving 150 miles with your Newman type electroscooter instead
of just 20 miles with normal DC motor electroscooter with one charge will
be a big difference...

Regards, Stefan.

Hi Michelinho,
do you make test for overunity with your Newman motors?
What you can say - overunity or not?
