Abstract

The invention discloses a unilateral magnetic adjustment-based double-rotor and double-winding cylindrical linear generator, belongs to the field of linear generators for wave power generation and aims at solving the problem that an existing direct-driven wave power generation system is relatively poor in power generation quality. The unilateral magnetic adjustment-based double-rotor and double-winding cylindrical linear generator comprises a casing, a double-winding stator, a permanent-magnet rotor, a modulation rotor, a permanent-magnet rotor output shaft and a modulation rotor output shaft, wherein the double-winding stator is fixed on the inner circle surface of the casing; the permanent-magnet rotor and the modulation rotor are sequentially arranged in the double-winding stator from outside to inside; the modulation rotor is fixed on the modulation rotor output shaft; the right end of the modulation rotor output shaft extends outside from an end cover at the right side of the casing; the permanent-magnet rotor is located between the double-winding stator and the modulation rotor; two ends of the permanent-magnet rotor extend outside from the end covers at two sides of the casing separately; the extension part at the left side is taken as the permanent-magnet rotor output shaft; and the axis of the permanent-magnet rotor output shaft overlaps with that of the modulation rotor output shaft.

Description

technical field [0001] The invention belongs to the field of linear generators for wave power generation. Background technique [0002] Ocean wave energy is a kind of clean power generation energy, which can meet the needs of ocean observation instruments, military and civilian test buoys, Dokdo, and operating platforms through wave energy power generation. At present, traditional wave energy power generation methods usually use mechanical devices to convert the up and down linear motion of waves into rotational motion, and drive the rotating generator to generate electricity. In contrast, the direct drive power generation method directly combines the energy recovery device and the linear motor to generate power, eliminating the need for complex mechanical transmission links in the middle, which improves the power generation efficiency of the system, and at the same time improves the integration and stability of the power generation system. improved. Therefore, direct driv...
