The Ossie motor

[gyulasun]

What matters is the resulting power from the output current and voltage received from the pickups.
Try to use the 3 pickups in series (watch for correct polarity not to ruin the induced voltages in antiphase) to make the forward voltage drop-loss due to the diode bridge negligible wrt the summed voltage output.

Unfortunately, in your present setup if you load the rotor (by inducing current in the pickups, for instance) this load will reflect in an increased current draw from the battery. Some kind of tricks are needed like Ossie showing...

Hey Jim

The pu coil should be on a bridge rectifier. Connect the pu to the ac end of the bridge, and the cap to the dc side.
If you are using led's, red ones will be brighter at 2v than blue or white, as they need 4v to light properly.
If the red ones are dim, then try a different pu coil.

Here is an idea, run one of your drive coils as a pu. Keep it away from the rotor at first, get the motor up to speed, and slowly bring in the big pu coil and see what haps.

Hi Jim,

Look at the first post in this link here, the circuit shown by 'lanenal' is a possibility to utilize the collapsing field's energy for supplying back most of the energy taken from the battery.  (Kind of variant of one of the circuits Ossie showed, but I have seen this similarly from P. Lindemann.)  I do not mean this is a magical circuit and by no means OU, just recapture some energy otherwise wasted.

@mags I have the BR setup & working. I have attached a cap. The leds were white & dim. The voltage I see over the cap atm is only 1.5v I think rpms being only at 650 atm is the issue. Battery voltage is 1.317 has been steadily rising about 0.007 so far. Just trying to work out how I get that voltage back into the motor.

Thanks Gyula. My wife is away this weekend so I am spending it trying to nail this Had a look at the circuit but I'll have to look at it several more times b4 I can work out how to implement thanks. I love Lindemanns work so I'll pay close attention. I haven't measured the current on the pu coils yet as it is diff with my current setup (pun intended).
