The invention relates to the field of wind power generation, in particular to a high-speed permanent magnet generator. The high-speed permanent magnet generator includes a first power generation bin and a lower wind wheel group; the lower wind wheel group includes a first closed frame, a turret, and six fan blades; the first closed frame includes a straight side parallel to the wind direction, and the length of the straight side is greater than or is equal to one third of the circumference of the first closing frame; the turret includes a vertically extending fixed cylinder and six sliding rails, one end of the sliding rail is fixed to the fixed cylinder and extends radially along the fixed cylinder; its rotation axis passes through the first A point on the vertical line of the straight side of the closed frame; each fan blade is provided with a rotating shaft, and each rotating shaft is rotatably and movably installed on a sliding rail, and rotates along the inner peripheral surface of the first closed frame; on the fan blade A limiting block is arranged to prevent the fan blade from rotating relative to the sliding rail after contacting with the sliding rail; one end of the fixed cylinder is rotated into the first power generation bin. When the fan blades rotate, at least two fan blades turn to the straight side and are parallel to the wind direction, which reduces the contact area between the drag crosswind and the fan blades.
Description
technical field [0001] The invention relates to the field of wind power generation, in particular to a high-speed permanent magnet generator. Background technique [0002] Wind turbines are divided into vertical axis generators and horizontal axis generators. Due to the large weight of the impeller itself, the horizontal axis generator needs to reduce the speed of the main shaft of the impeller. Vertical axis generators, however, are not required. In order to maintain the rotational speed of the existing vertical axis wind turbine, it is necessary to reduce the resistance to the wind when the blades rotate to the resistance side, so that the rotational speed of the impeller can reach the highest level under the condition of the same wind energy. In the existing pan-swing wind turbine, when the blade swings to the resistance side, it becomes a vertical plate parallel to the wind direction. However, since there are many blades and there is a certain thickness, there is still ...
