Description
Technical field
The present invention relates to a kind of wind-driven generator, a kind of split type external rotor wind driven electric generator of more specifically saying so.
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 transportation and mounting cost, and brought many inconvenience for again transportation and installation.
Summary of the invention
The purpose of this invention is to provide a kind of split type external rotor wind driven electric generator of transporting and installing be convenient to.
In order to realize above-mentioned purpose, the split type external rotor wind 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 inner stator frame on the central shaft and be connected to the external rotor dish by bearing, the external rotor dish is provided with ringwise external rotor shell, the windward side of external rotor dish is streamlined, be connected with blade on it, on the cylindrical anchor ring of inner stator frame, be inlaid with equally distributed stator iron core, be wound with the three-phase coil winding on the stator iron core, be inlaid with equally distributed permanent-magnet on the inner side surface of rotor shell corresponding to stator iron core and three-phase coil winding position outside, leave air gap between permanent-magnet and the stator iron core, its structural feature is that the external rotor 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 rotor wind driven electric generator provided by the present invention, be directly to drive the external rotor dish by blade to rotate, the permanent-magnet that is embedded on the external rotor shell inner side surface rotates thereupon synchronously, is embedded in the three-phase coil winding cutting magnetic line on the inner stator frame cylindrical anchor ring, produces induction electromotive force.The external rotor 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 and has transported and the expense of installation, has made things convenient for transportation, has reduced installation difficulty again.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.
