Unilateral magnetic adjustment principle-based double-rotor and double-winding flat linear generator

Abstract

The invention discloses a unilateral magnetic adjustment principle-based double-rotor and double-winding flat 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 principle-based double-rotor and double-winding flat linear generator comprises a casing, a double-winding stator, a permanent-magnet stator, a permanent-magnet rotor, a modulation rotor, a permanent-magnet rotor output end and a modulation rotor output end, wherein the double-winding stator is symmetrically fixed on the upper and lower inner surfaces of the casing by employing an axis plane as the symmetric plane; the modulation rotor is arranged in the double-winding stator; the permanent-magnet rotor is arranged between the modulation rotor and the double-winding stator; the right end of the modulation rotor extends outside from an end cover at the right side of the casing as the modulation rotor output end; the permanent-magnet rotor is of a symmetric structure employing the axis plane as the symmetric plane; two ends of the permanent-magnet rotor extend outside from the end covers at two sides of the casing; the extension part at the left side is taken as the permanent-magnet rotor output end; and the axial symmetric plane of the permanent-magnet rotor output end overlaps with that of the modulation rotor output end.

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...
