Contactless generator and application thereof

Abstract

A contactless generator includes a generating module and a magnetic module. The generating module includes an energy converter and a rotator. The rotator has a surface and mechanical energy when rotating and is rotatable relative to the energy converter. The magnetic module is mounted on the surface of the rotator, aligned with the energy converter, and produces an intrinsic magnetic field. The intrinsic magnetic field is subjected to a contactless active force from an external magnetic field and drives the rotator to rotate. The energy converter senses partial intrinsic magnetic field of the magnetic module and converts mechanical energy of the rotator when rotating into electricity by a converting means. The external magnetic field is generated through sensing the intrinsic magnetic field by a metal moving object.

Description

technical field [0001] The invention relates to a contactless power generation device and its application. Background technique [0002] Most of the existing generators currently convert mechanical energy into electrical energy. Taking the bicycle or car field as an example, in order to avoid the use of batteries, contact generators or magic hubs are the mainstream in the market. However, contact generators or magic hubs have their own restrictions and inconveniences in use: [0003] (1) Please refer to Figure 10 , a contact generator 60 must directly contact a wheel or the surface of the rim 52, and when the wheel rotates (A), it drives the partial rotation (B) of the contact generator 60, and the contact generator 60 will rotate mechanical energy Converted to electrical energy output. However, although electric energy can be generated during contact, it will increase the force required for riding by the user, resulting in bad feeling or physical exertion. [0004] (2) ...

AI Technical Summary

Problems solved by technology

However, although electric energy can be generated during contact, it will increase the force required for the user to ride, resulting in a bad feeling or physical exertion.

[0004] (2) Although the hub dynamo has a better feeling than the contact generator, it must be directly integrated and installed on the wheel. Users cannot install or adjust the position by themselves, and the purchase and maintenance costs are high.
