Problems solved by technology

[0003] The problem existing in the existing wind power generator is: the rotating part of the generator bears the weight of the blades, which makes the rotation of the rotating part difficult. If other supporting structures are used to share the weight carried by the rotating part, there will be problems with the cooperation between the generator and the rest. complex questions

Abstract

The invention discloses a drag-lift type composite medium-sized magnetic suspension wind driven generator which comprises a column tower, a generator motor and blades. The generator motor comprises a rotating portion, a fixed plate and a rotating plate, wherein the rotating portion is connected with the blades and is driven to rotate by the blades; the fixed plate is fixed on the column tower; the rotating plate is matched with the generator motor and is connected with the blades; a magnetic suspension device is arranged between the fixed plate and the rotating plate; the generator motor comprises a first column and a cylindrical rotating portion, the first column is fixedly carried by the fixed plate, the cylindrical rotating portion rotates around the first column, splines are outwards convexly arranged on the outer surface of the rotating portion, at least one interference portion is fixed on the rotating plate, and each interference portion is inserted between the corresponding two splines and interferes with the two splines; the rotating plate shares the weight carried by the rotating portion; and the rotating portion of the generator motor is provided with the splines which are matched with the interference portions on the rotating plate. The drag-lift type composite medium-sized magnetic suspension wind driven generator is simple and practical in structure, and manufacture and assembly costs are effectively reduced.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a wind power generator. Background technique [0002] Under the general trend of global energy saving, environmental protection and sustainable development, the development of wind turbines has been vigorously promoted. Existing wind generators generally include blades for being rotated by the wind, a rotating part (generator rotor) driven by the blades, and a generator stator. The blades of the generator rotate to drive the rotating part to generate electricity. The existing wind power generator also includes a control system, a cooling element for cooling the generator, an anemometer, a wind vane, and the like. [0003] The problem existing in the existing wind power generator is: the rotating part of the generator bears the weight of the blades, which makes the rotation of the rotating part difficult. If other supporting structures are used to share the weight carried by the rotatin...
