The invention relates to a permanent magnet wind power generator with torque gradient adjustment, comprising: fan blades, connecting rods, stators, rotors and a casing; the casing has a housing cavity, and the stator and the rotor are accommodated in the housing cavity The stator is provided with a plurality of permanent magnets, the rotor is connected to the connecting rod, and the connecting rod is connected to the fan blade after extending out of the housing from the housing cavity; the torque gradient adjustment The permanent magnet wind power generator also includes an adaptive adjustment component, which is accommodated in the accommodation cavity and connected to the connecting rod; the adaptive adjustment component drives the stator to slide along the connecting rod, so that the stator approaches or moves away from the rotor. The permanent magnet wind power generator with torque gradient adjustment provided by the present invention adjusts the coupling degree between the stator and the rotor through the self-adaptive adjustment mechanism, so as to realize passive self-tendency self-adaptive adjustment of torque, thereby reducing the starting inertia and achieving small wind power starting.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a permanent magnet wind generator with torque gradient adjustment. Background technique [0002] Wind power is becoming more and more popular as a clean energy source. The principle of wind power generation is: the wind turbine blades are driven to rotate by natural wind, and the speed of rotation is increased by the speed increaser to promote the power generation equipment to generate electricity. In short, wind power is the process of converting wind energy into mechanical energy, and then mechanical energy into electrical energy. This process requires no fuel, no radiation, no pollution to the air and the environment, and is a clean energy source. [0003] For example, the invention patent: torque-adjustable permanent magnet variable speed wind power generation device, the publication number is CN104500344A, the recorded wind power generation device has the fol...
