Design and performance analysis of trapezoid Halbach array magnetic couplings for Ocean current turbine generator

At present, the use of new energy in the world has become more and more important. Ocean current turbine generator is a device that converts the ocean current energy into electrical energy to solve the energy supply of the underwater platform. As shown in Figure 1, the blades and the generator are connected by magnetic couplings, the ocean current drives the blades to rotate, and then the generator is driven by magnetic couplings, so as to convert the ocean current energy into electrical energy. Therefore, the performance of magnetic couplings plays a very important role in the Ocean current turbine generator.
