The invention relates to a 2.5MW direct-driven wind turbine generator inner stator coil and a manufacturing method thereof. The 2.5MW direct-driven wind turbine generator inner stator coil comprises a coil body formed by flatly winding a single polyimide F46 composite film sintering polyester film mica tape winding wire, wherein the number of turns of the coil body is 10-14; the cross section of an inner conductor of the F46 composite film sintering polyester film mica tape winding wire is rectangular in shape, the thickness is 3.5-4.2mm, the width is 15-18mm, and the thickness of an outer insulating layer of the polyimide F46 composite film sintering polyester film mica tape winding wire is 0.3-0.5mm; and the coil body comprises an upper straight-line portion located at the upper part and a lower straight-line portion located at the lower part, the left side of the upper straight-line portion and the left side of the lower straight-line portion are connected through a left-end nose portion, and the right side of the upper straight-line portion and the right side of the lower straight-line portion are connected with a right-end nose portion. The 2.5MW direct-driven wind turbine generator inner stator coil has good ground insulation and turn-to-turn insulation, and has higher mechanical strength. In addition, the 2.5MW direct-driven wind turbine generator inner stator coil is simple in structure and easy to manufacture, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of wind power generators, in particular to an inner stator coil of a 2.5MW direct drive wind power generator and a manufacturing method thereof. Background technique [0002] Compared with generators in other fields, generators in the field of wind power generation are mostly direct-drive wind generators. This is because ordinary generators are equipped with gearboxes, which will reduce the efficiency of wind power transmission, and the gears The box is a wearing part, which requires frequent maintenance, and the use cost and maintenance cost are relatively high, which is not conducive to the industrialization of wind power generators. The types of direct drive wind power generators can generally be divided into inner rotor wind power generators and outer rotor wind power generators. The present invention relates to an inner stator coil of an outer rotor wind power generator. [0003] With the development o...
