DougI have never tinkered with the windings on my DC motors to see just where they go. I have quite a few of them, and might be able to perhaps spare one for science.However, high on my agenda, is replicating our daisy chain motor experiment, which oddly enough, might be barking at a similar phenomena.
I think Hector might have been quietly sitting on this info for decades. I do find it is so hard to understand.There is that sloppy moment when brushes arc, hence, the diode bridge trick, to quench that arc, and save it, to pass it on to the next motor.Hector's idea is just more efficient in terms of iron, and copper mass, keeping the the mess a lot more tidy, than stretching it out along a long table, lined with motors.I think my experiment just relies on the sloppy overlap in timing of the motors, perhaps?I am pretty ignorant of the fine details of DC motor engineering, and I am sure that Dayton etc, don't publish their trade secrets, so much.Cheers Warren

Hi That
Maybe fields not meant to alternate polarity. But rather all pulsed one way then flyback spike and perhaps actual back emf is harvested?
Perhaps flyback spike harvested and back emf cancelled?
Left out in diagram I think is rotovertor mode with For example if 3ph motor, 2 phases pulsed and 3rd phase bridged with cap (somehow) l wonder how that would work in DC
