Description

technical field [0001] The present invention relates to an internally controlled pole-changing power generation technology for multi-field applications such as active magnetism, and in particular to a device that uses an internal I-shaped magnetic conductor to control the forward and reverse directions of the wire-wrapped current and the size of the wire-wrapped current; And water power generators and power generation devices using unequal speed drives (referred to as "internal control pole-changing power generation system"). Background technique [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; The difference in power generation is large when the machine speed ratio is large; the cost of mul...

[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
