Abstract

Provided is a cylindrical traverse flux permanent magnet synchronous linear generator. The cylindrical traverse flux permanent magnet synchronous linear generator comprises a primary side (1) and a secondary side (2) which are both cylindrical and in traverse flux. The primary side (1) comprises an A-phase primary iron core (3), a B-phase primary iron core (4), a C-phase primary iron core (5) andtrack-type windings (9), and the track-type windings (9) wind around tooth pole bodies of the primary iron cores. The secondary side (2) comprises secondary iron core units (6), magnetic-insulated sheets (7) and secondary magnetic steel (8), the secondary magnetic steel (8) is nested in the secondary iron core units (6), the secondary iron core units (6) and the magnetic-insulated sheets (7) are arranged at intervals, secondary permanent magnets are nested in the secondary iron core units (6), the cylindrical primary side (1) and the secondary side (2) in the traverse flux are arranged in a concentric manner, the outer side of the secondary side (2) is sleeved by the primary side (1), and an air gap is arranged between tooth pole shoes of the primary side and the surface of the secondary side. The cylindrical traverse flux permanent magnet synchronous linear generator is used for a direct-driven wave energy generation system.

Description

technical field [0001] The invention relates to a linear generator, in particular to a transverse flux permanent magnet synchronous linear generator. Background technique [0002] In the wave energy power generation system, there are two ways to extract the energy of the linear motion of the wave energy. One is to use a mechanical transmission device to convert the linear motion into a rotary motion, such as connecting a pneumatic system, a hydraulic system or a gearbox, etc., but the intermediate links are complicated. , reducing the reliability and conversion efficiency of the system. Second, use a linear generator. The method does not need any intermediate mechanism, and the structure is simple in this way, which improves the efficiency and reliability of the system. However, the power density of linear generator systems is generally lower than that of rotary motor systems [0003] In order to improve the power density of permanent magnet linear motors, some scholars h...
