Abstract

A double-rotor and double-winding flat-plate linear generator based on a magnetic field modulation principle belongs to the field of linear generators for wave power generation. The invention aims to solve the problem that the existing direct-driven wave power generation system is of poor quality of power generation. The linear generator comprises a casing, a double-winding stator, a permanent-magnetic rotor, a modulation rotor, a permanent-magnetic rotor output end, and a modulation rotor output end. The double-winding stator is symmetrically fixed to the upper and lower inner surfaces of the casing with the axial plane as a plane of symmetry. The permanent-magnetic rotor is arranged inside the double-winding stator. The modulation rotor is arranged between the permanent-magnetic rotor and the double-winding stator. The right end of the permanent-magnetic rotor extends out of a right end cover of the casing as the permanent-magnetic rotor output end. The modulation rotor is of a symmetric structure with the axial plane as a plane of symmetry. The left side of the modulation rotor extends out of the shell as the modulation rotor output end. The axially symmetric planes of the permanent-magnetic rotor output end and the modulation rotor output end coincide with each other.

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...
