Magnet to magnet couplings and drives

A balanced magnetic rotor assembly comprising:

• a driver rotor assembly having a first driver rotor and a second driver rotor arranged about a rotational axis and being spaced apart from each other a distance along the rotational axis:
• the first driver rotor including a first array of a first plurality of magnets coupled to a first plate, the first array of the first plurality of magnets arranged in a first plane that is perpendicular to the rotational axis of the driver rotor assembly, a first of the first plurality of magnets having a north pole face in a first direction and being arranged between a second and a third of the first plurality of magnets, the second and the third of the first plurality of magnets having a south pole face also in the first direction;
• the second driver rotor including a second array of a second plurality of magnets coupled to a second plate, the second array of the second plurality of magnets arranged in a second plane that is perpendicular to the rotational axis of the driver rotor assembly and parallel to the first plane, a first of the second plurality of magnets having a south pole face in a second direction and being arranged between a second and a third of the second plurality of magnets, the second and the third of the second plurality of magnets having a north pole face also in the second direction;
• and
• a load rotor being arranged about the rotational axis and arranged between the first driver rotor and the second driver rotor, the load rotor including a body having a third array of a third plurality of magnets therein, the third array of the third plurality of magnets arranged in a third plane that is perpendicular to the rotational axis of the driver rotor assembly and parallel to the first and second planes, a first of the third plurality of magnets having a north pole face in the first direction and a south pole face in the second direction and being arranged between a second and a third of the third plurality of magnets, the second and the third of the third plurality of magnets each having a south pole face in the first direction and a north pole face in the second direction.
