Magnetic Rotor Designs and Systems

A fluid-flow system comprising:

• a fluid-flow assembly comprising an internal magnetic array coupled to at least one set of rotor blades, wherein the internal magnetic array comprises magnets arranged to provide alternating polarity around the outside of the internal magnetic array;
• and
• at least one external magnet;
• wherein the internal magnetic array and the at least one external magnet are not in physical contact with each other;
• wherein the internal magnetic array and the at least one external magnet are arranged such that when the internal magnetic array is rotated, the rotation of the internal magnetic array magnetically induces actuation of the at least one external magnet;
• and
• wherein the internal magnetic array and the at least one set of rotor blades are arranged such that a fluid flow that causes rotation of the at least one set of rotor blades results in rotation of the internal magnetic array, thereby inducing actuation of the at least one external magnet.

A magnetic rotor system comprising:

• a first magnetic array comprising magnets arranged to provide alternating polarity around the outside of the first magnetic array;
• and
• a second magnetic array comprising magnets arranged to provide alternating polarity around the outside of the second magnetic array;
• wherein the first magnetic array and the second magnetic array are not in physical contact with each other;
• wherein the first magnetic array and the second magnetic array are arranged such that when the first magnetic array is rotated, the rotation of the first magnetic array magnetically induces rotation of the second magnetic array;
• wherein the first magnetic array has a first number of polarity changes around the outside of the first magnetic array;
• wherein the second magnetic array has a second number of polarity changes around the outside of the second magnetic array;
• and
• wherein the second number of polarity changes differs from the first number of polarity changes.
