Description

Technical Field

[0001] The utility model relates to the technical field of power generation devices, in particular to a high-efficiency linear generator. Background Art

[0002] A linear generator is a device that converts linear motion directly into electrical energy. Unlike a rotary generator, a linear generator has no mechanical rotating parts. Since there are no complex rotating parts, the maintenance cost is lower. A linear generator achieves energy conversion by utilizing the relative motion of a magnetic field and a conductor to generate current.

[0003] However, the existing linear generator generates electricity by driving the core shaft to move through the waves and interacting with the coil to generate current. This method is only suitable for locations with larger waves. When the waves are smaller, the movement amplitude of the core shaft will be reduced, resulting in lower power generation efficiency of the generator. After searching, it was found that the technical solution provided by the utility model with application number CN202022927491.8 also has the above-mentioned problems. Utility Model Content
