Linear generator

Abstract

The invention discloses a linear generator, which comprises at least one power generation unit, and is characterized in that the power generation unit comprises a rotor part and a stator part; the rotor part comprises a rotor shaft, a magnet base and two annular magnets, the magnet base is arranged in the middle of the rotor shaft in a flange-shaped winding mode, and the two annular magnets are arranged on the rotor shaft on the two sides of the magnet base in a sleeving mode in a same-direction opposite-pole attraction mode; wherein the stator part comprises two power generation windings anda clamping seat for fixing the windings, the clamping seat comprises a bottom frame and a U-shaped clamping groove, the power generation windings are clamped in the U-shaped clamping groove, and the two end parts of the rotor shaft are respectively inserted into the two power generation windings in a penetrating manner and are erected by the clamping seat. The winding capacity is larger, and moreelectric energy can be generated; the annular magnet has a larger sectional area, and the magnetic field with the maximum sectional area is completely utilized, so that the magnetic field intensity isstronger; the power generation voltage is higher, the output capacity is higher, the sufficient power output by the internal combustion engine is achieved through adaptation, the overall size is reduced, and the material cost is saved.

Description

technical field [0001] The present invention relates to a power generation device, in particular to a linear generator. Background technique [0002] Linear generators are generally used as matching generators for linear internal combustion engines. Since linear internal combustion engines are mostly used in the field of range extenders, the efficiency and power density of linear generators have always been technical difficulties. [0003] The schematic diagram of the linear generator in the prior art is as follows figure 1 As shown, the method of using multiple magnets and multiple windings in series induction power generation is generally used. Since the deflagration driving force of the internal combustion engine is often greater than the full power load braking force of the generator winding, the output power is difficult to match the output power of the internal combustion engine itself. When there is a technical solution, the large output winding capacity is limited b...

[0003] The schematic diagram of the principle of the linear generator in the prior art is as figure 1 As shown, the method of inductive power generation with multiple magnets and multiple windings in series is generally used. Since the deflagration driving force of the internal combustion engine is often greater than the full-power load braking force of the generator winding, the output power is difficult to match the output power of the internal combustion engine itself. When there is a technical solution, the large output winding capacity is limited by the volume of the internal combustion engine and the generator itself, so the efficiency is not high
