Abstract

The invention discloses a rectilinear cylindrical switching magnetic flux permanent magnet generator, which is a rectilinear cylindrical permanent magnet generator with simple structure, high efficiency and low cost. The generator can be used in a directly driven ocean wave generating device and a rectilinear generating system of other types, does not need an intermediate transmission structure and an intermediate transmission device, and simplifies a generating system. The generator comprises a U-shaped iron core (2.1) of a primary stator (2), a permanent magnet (2.2), a non-magnetizer spacer (2.3), a primary three-phase winding (3) and a secondary rotor (1); the whole motor has a cylindrical structure, the U-shaped iron core (2.1) and the permanent magnet (2.2) are positioned outside the rotor (1), the primary three-phase winding (3) is embedded into a slot of the U-shaped iron core (2.1), the rotor (1) is positioned in the center of the motor, and annular teeth (1.1) and grooves (1.2) spaced in equal distance are arranged on the periphery of the rotor (1); and an air gap is reserved between the primary U-shaped iron core (2.1) and the secondary rotor (1) of the motor.

Description

technical field [0001] The invention relates to a new linear cylindrical switched flux permanent magnet generator, which is mainly used in the fields of ocean wave power generation and linear motion power generation. Background technique [0002] Traditional energy sources such as coal and oil are decreasing day by day, causing global environmental problems. The use of clean energy and renewable energy has received more attention. Ocean wave energy in ocean energy is a kind of clean energy, and there is a large amount of wave energy stored on the surface of the earth. Research on wave energy extraction devices has been going on for many years. As a power generation device that directly converts ocean waves into electrical energy, ocean wave generators have been researched by domestic and foreign scholars and companies. Currently used wave generators are mostly wave devices with permanent magnet mechanisms. There are mainly linear generators that generate electricity by d...

Problems solved by technology

On the one hand, the structure of the mover and the processing technology of the permanent magnet are relatively complicated for this kind of linear generator. On the other hand, the linear generator with the mover and the permanent magnet has a large permanent magnet coercive force, which causes distortion and distortion of the power generation waveform. The vibration of the mechanical structure affects the power generation performance of the generator
