Embodiment Construction

[0018] The invention provides a magnetic gear composite multi-port wave generator. When working in the power generation state, it can be applied in new energy development fields such as wave power generation. It directly converts the low-speed motion of the wave energy conversion device into high-speed motion and generates power, increasing the power density of the entire system.

[0019] Structurally, the motor is mainly composed of five concentric parts. The inner rotor 7 of the motor, the stator 5 of the motor, the inner rotor of the magnetic gear (the outer rotor of the motor) 4, the magnetic adjustment ring 3 and the outer rotor of the magnetic gear are arranged in sequence from the inside to the outside. 1. Specifically, the magnetic gear composite multi-port wave generator can be equivalently composed of a coaxial magnetic gear and an inner rotor permanent magnet motor. Wherein the coaxial magnetic gear is composed of a magnetic gear outer rotor 1, a magnetic adjustmen...

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...
