The outer stator support is fixedly connected with an outer stator case, and the upwind end of an inner rotor disk case is fixedly connected with a blade. A stator core is embedded on the inner side of the outer stator case and wrapped with a three-phase coil winding. A permanent magnet is embedded on the ring surface of the internal rotor disk, and an air gap is arranged between the permanent magnet and the stator core. The utility model is characterized in that the outer stator case is split into at least two parts, and the split parts are assembled together by bolts and cylindrical pins with internal threads. The split outer stator wind power generator can be transported and installed by utilizing common transportation means and hoisting equipment, with the advantages of low cost, convenient transportation and reduced installation difficulty.
Description
Technical field
The utility model relates to a kind of split type external stator nwind driven electric generator.
Background technique
Along with continuous advancement in technology, the single-machine capacity of high-power grid type wind-driven generator is increasing, its volume is then increasing, weight is more and more heavier, again because the whole generating machine is an integral body, must use superhuge means of transportation and crane gear just to transport and install, both increase cost, and brought many inconvenience for again transportation and installation.
Summary of the invention
The purpose of this utility model provides a kind of split type external stator nwind driven electric generator of transporting and installing be convenient to.
In order to realize above-mentioned purpose, the split type external stator nwind driven electric generator that is provided, comprise pylon, the upper end of pylon is connected to solid of rotation by bearing, solid of rotation is fixed in the inner chamber in cabin, on solid of rotation, be connected with central shaft, be connected with the external stator frame on the central shaft and be connected to the internal rotor dish by bearing, be connected with ringwise external stator shell on the external stator frame, the windward side of internal rotor disk casing is streamlined, be connected with blade on it, be inlaid with equally distributed stator iron core on the inner side surface of stator case outside, be wound with the three-phase coil winding on the stator iron core, on the anchor ring of internal rotor dish, be inlaid with equally distributed permanent-magnet corresponding to stator iron core and three-phase coil winding position, leave air gap between permanent-magnet and the stator iron core, its structural feature is that the external stator shell is split, and the quantity of its split is two bodies at least, is assembled into one with bolt and cylindrical pin with internal thread between the split.
The rear in above-mentioned cabin is the hemisphere hull shape.
Split type external stator nwind driven electric generator provided by the utility model, be directly to drive the internal rotor dish by blade to rotate, the permanent-magnet that is embedded on the internal rotor disk ring face rotates thereupon synchronously, is embedded in the three-phase coil winding cutting magnetic line in the external stator shell, produces induction electromotive force.The external stator shell adopt to divide a body structure, and the wind-driven generator of an integral body is divided into several parts, uses general means of transportation and crane gear just to transport and install, and has both reduced cost, has made things convenient for transportation again, has also reduced installation difficulty.The rear in cabin is designed to be the hemisphere hull shape, when making distinguished and admirable arrival cabin rear, can produce big turbulent flow and wake flow, the whole wind power generator is produced a reciprocal active force, so the power that affacts on the pylon is just very little, effectively increase stability of tower, strengthened wind loading rating.
