Hi,
this is an Earth Pole DC motor which I designed and built.
It is very interesting and rewarding to to give it a try as it demonstrates profound concepts
with few components promoting further understanding of the concepts.
The polarity on the armature is shifted accordingly (+/-12V) instead of simply switching ON and Off.
The Unit is first aligned towards the North Pole which is the optimal position for fastest rotation, then it is rotated by 90 degrees to a bad position where the Motor slows down to a dead stop to indicate the North direction.
