This is a test for recycling the kickback spike on a pulse motor, to recharge a battery. The motor coil is a MO fan motor cut in 2 (a la Mranguswangus). The rotor is a 6 pole neomagnet . All poles are north out . A reed switch a la Ossie motor, gives the pulse to drive the motor. It spins very regularly. The speed depends of the reed position, but the greater the speed the greater the current draw. And it works, the motor spins while recharging the battery.
What is interesting is that it seems that the motor battery voltage drop is less than the charging battery voltage goes up. I don't know what i can do with this , but it is anyway interesting. Need further test to confirm.
