Embodiment Construction
[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to a permanent magnet wind power generator with stepless self-adaptive adjustment of torque, comprising: a base, a housing, a stator, a rotor, a connecting rod and blades, the base cooperates with the housing to form a storage cavity, and the stator and the rotor are accommodated in the storage cavity ; One end of the connecting rod is connected to the rotor, and the other end extends out of the housing from the housing and is connected to the fan blade; the stator is provided with a plurality of permanent magnets, and the stator is connected to the base through the first return spring, which provides the stator with The elastic restoring force makes the stator have a tendency to move away from the rotor; the permanent magnet wind power generator with stepless torque self-adaptive adjustment also includes an self-adaptive adjustment component, which is accommodated in the accommodation cavity and connected with the connecting rod. The permanent magnet wind power generator with stepless torque self-adaptive adjustment disclosed by the present invention adjusts the coupling degree between the stator and the rotor through an self-adaptive adjustment mechanism to realize passive self-tendency self-adaptive adjustment of torque, thereby reducing the starting inertia and achieving a small The wind starts.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a permanent magnet wind power generator with stepless torque self-adaptive adjustment. Background technique [0002] As a clean energy source, wind power is becoming more and more popular. The principle of wind power generation is: the windmill blades are driven to rotate by natural wind, and the speed of rotation is increased through the speed increaser to promote the power generation equipment to generate electricity. In short, wind power generation is the process of converting wind energy into mechanical energy and then converting mechanical energy into electrical energy. This process does not require fuel, has no radiation, does not pollute the air and the environment, and is a clean energy source. [0003] Such as the invention patent: adjustable torque permanent magnet variable speed wind power generation device, the publication number is CN104500344A, the w...
