Generator with minimal to non-existent rotation resistance through controlled attractions among all magnets and iron cores

A generator, comprising:

• a frame;
• an axis coupled to the frame;
• N segments of magnets arranged along the axis, each segment of the N segments of magnets including N−1 magnets arranged in a first plane orthogonal to the axis;
• and
• N sets of iron cores arranged along the axis, each set of the N sets of iron cores including N−1 iron cores arranged in a second plane orthogonal to the axis, each set of the N sets of iron cores adjacent to a corresponding segment of the N segments of magnets, and the second plane substantially parallel to the first plane,
• wherein when N−1 magnets of a first segment of magnets fully align with N−1 iron cores of a corresponding first set of iron cores, magnets of other segments of the N segments of magnets each misalign with iron cores of the corresponding sets of iron cores,
• wherein the N segments of magnets each includes a different magnet of a first group of magnets arranged helically along the axis, the first group of magnets each being discrete and separated from one another, and
• wherein the N sets of iron cores each includes a different iron core of a first group of iron cores arranged helically along the axis, the first group of iron cores each being discrete and separated from one another.

A generator comprising:

• a frame;
• an axis coupled to the frame;
• N magnet groups each including N magnets arranged helically along the axis, the N magnets being discrete and separated from one another;
• and
• N set of iron cores arranged along the axis, each set of the N sets of iron cores including Q iron cores arranged in a plane substantially orthogonal to the axis, wherein Q is different from N, wherein the N sets of iron cores each includes a different iron core of a first group of iron cores arranged helically along the axis, the first group of iron cores each being discrete and separated from one another.

A generator, comprising:

• a frame;
• an axis coupled to the frame;
• a first group of magnets arranged helically along the axis, the first group of magnets each being discrete and separated from one another;
• and
• a first group of iron cores arranged helically along the axis, the first group of iron cores each being discrete and separated from one another,
• wherein in operation when the first group of magnets rotate with the axis, in a time point, each magnet of the first group of magnets is in one of three states including:
• a first state that a first attraction between the magnet and a first iron core of the first group of iron cores is balanced by a second attraction between another magnet of the first group of magnets and a second iron core of the first group of iron cores;
• a second state that the magnet is fully aligned with an iron core of the first group of iron cores;
• and
• a third state that a third attraction between the magnet and a third iron core of the first group of iron cores is balanced by a fourth attraction between the magnet and a fourth iron core of the first group of iron.
