Problems solved by technology

[0002] At present, frequency conversion technology cannot be applied to generators because the frequency of the power grid is a fixed value. New energy wind turbines and hydropower generators cannot uniformly drive generators due to wind speed and flow velocity, resulting in unequal power generation and unstable voltage fluctuations; Large machine speed ratio and large difference in power generation; multi-pole low-speed and direct-drive generators are expensive, the process structure requires high precision, and permanent magnets are easily affected by other magnets, making it difficult to replace demagnetization and loss of magnetism
