Magnetic-gear composite multi-port wave generator

Abstract

The invention relates to a magnetic gear composite multiport wave power generator, mainly composed of five concentric components. A motor inner rotor, a motor stator, a magnetic gear inner rotor, namely, a motor outer rotor, a magnetic modulation ring and a magnetic gear outer rotor are set in sequence from outside to inside. The motor inner rotor is equipped with permanent magnet and an inner rotor winding. Rotor slots are uniformly distributed on the motor rotor and are used for embedding an armature winding and a dual-redundancy winding structure is employed, so the fault-tolerant operatingcapability of a motor system is improved. The magnetic gear inner rotor is arranged at periphery space of the stator. The magnetic gear inner rotor is an annular structure. Permanent magnet poles aremounted on the outer surface of the annular structure. The magnetic modulation ring of a coaxial magnetic gear is arranged at the periphery space of the magnetic gear inner rotor. The magnetic gear outer rotor is arranged at the periphery space of the magnetic modulation ring. The magnetic gear outer rotor comprises a structure support element and a magnetic conductive iron core. The permanent magnet poles are assembled on the inner surface of the magnetic conductive iron core. The magnetic gear outer rotor and the motor inner rotor are respectively connected with a set of wave energy conversion devices.

Description

technical field [0001] The invention belongs to the field of electrical design, in particular to a composite multi-port electrical device based on magnetic field modulation. Background technique [0002] Ocean wave power generation is a promising renewable energy power generation, which has attracted the attention of countries all over the world in recent years. According to the observation of relevant departments, the wave energy density in my country's sea area is about 2-5kW / m, which shows that my country has abundant wave energy available. The wave generator is an important part of the Wave Energy Conversion (WEC) system, and its performance has a great influence on the stable operation of the wave power system and the fluctuation of output power. However, when most generators are used in WEC systems, they need to be combined with mechanical transmission mechanisms such as gearboxes to ensure the normal operation of the motor. Traditional mechanical gear transmission wi...
