Apparatus

A magnetic motor apparatus comprising:

• a motor housing;
• a rotor within the motor housing, wherein the rotor is configured to receive an initial force that causes the rotor to rotate from a force external to the motor apparatus and wherein the rotor will stop rotating after a time period without subsequent forces external to the motor apparatus, the rotor having
• an inner rotor part including a plurality of permanent arc magnets arranged in a first circle,
• an outer rotor part including a plurality of permanent arc magnets arranged in a second circle concentrically disposed around the inner rotor part, the inner rotor part and the outer rotor part being rotatable around a common central axis of rotation, and
• a plurality of shields arranged in a third circle concentrically around the outer rotor part;
• an output shaft extending along or substantially along the central axis of rotation and at least partly out of the housing, the output shaft being rotatable with the rotor, wherein the output shaft is configured to rotate to which rotation can produce a mechanical or electrical output for a period of time;
• a plurality of rotatable urging portion arranged in a fourth circle concentrically around the rotor and the plurality of shields, each rotatable urging portion including a permanent magnet having poles, and being rotatable around a peripheral axis of rotation such that, upon rotation of each rotatable urging portion, each said pole of the rotatable urging portion in-use alternatingly faces the rotor to impart an urging force thereon;
• and
• a locking mechanism arranged to control the rotation of the plurality of rotatable urging portions.
