Contactless generator, component therein and application thereof

摘要

A contactless generator includes a generating module (10) and a magnetic module (20). The generating module (10) includes an energy converter (16) and a rotator (12). The rotator (12) has a surface and mechanical energy when rotating and is rotatable relative to the energy converter (16). The magnetic module (20) is mounted on the surface of the rotator (12), aligned with the energy converter (16), and produces an intrinsic magnetic field. The intrinsic magnetic field is subjected to a contactless active force from an external contactless moving metallic object and drives the rotator (12) to rotate. The energy converter (16) converts mechanical energy of the rotator (12) when rotating into electricity by a converting means.
