With the structure type of the direct-drive permanent-magnet generator of rigid connection float.This kind of direct drive structure is for directly turning kinetic energy of wave
The power generation electric energy for permanent magnet generator is changed into, without intermediate transmission and bindiny mechanism.Therefore, the wave of direct-driving permanent magnetic motor
Power generator has less removable and rotation component, is also therefore wanted with lower complexity and associated maintenance
It asks.However, the integrally-built weight of the wave energy generating set of direct-driving permanent magnetic generator is usually heavier, volume is more huge
Greatly, and again the efficiency that the wave electricity under the reciprocal wave motion of low speed is converted is relatively low.Therefore, generally speaking, using linear motor direct-driven
The problems such as wave-power device of form is often with having power conversion efficiency relatively low and output power quality deviation.
To sum up, the kind of drive of the current wave energy generating set frequently with three types, and these three modes are equal
Have the shortcomings that a series of problems, such as various such as complicated, structural reliability is low and wave photoelectric transformation efficiency is relatively low, it is also more difficult
To apply the wave-energy power generation in off-lying sea on a large scale.
