The invention relates to a double-stator permanent magnetic direct drive generator and an assembly method thereof. The generator comprises a front bearing assembly, a rotor, an inner stator fitting, an outer stator fitting and a rear bearing assembly. The assembly method comprises the following steps of: inserting a guide rod into a top end mounting hole in a rear support of the rotor, and introducing and fixedly connecting the rotor; inserting a guide rod into a middle mounting hole of the rear support of the rotor, and mounting the inner stator fitting; inserting a guide rod into a mounting hole in a generator casing, passing the guide rod through a mounting hole in a rear flange, and mounting the outer stator fitting; mounting the front bearing assembly, and fixedly connecting a turntable of the rotor with the front end of the rotor; and fixedly connecting one end of a front flange with the front end of the generator casing, and fixedly connecting the other end of the front flange with the front bearing assembly. The fan-driven generator provided by the invention is high in output power of unit volume, and the assembly process difficulty and the cost of the large generator are reduced.
Description
technical field [0001] The invention relates to the field of permanent magnet direct drive generators, in particular to a double-stator permanent magnet direct drive generator and an assembly method thereof. Background technique [0002] The continuous upgrading of wind power technology has become the theme of the current domestic wind power industry, mainly manifested in the increase of stand-alone capacity, new technology wind turbines, and improvement of wind energy utilization. At the same time, more attention is paid to the safety of the unit and the reliability control of the system. The state strongly supports the development of offshore wind energy, and the development of offshore wind farms and the development of large-scale wind turbines suitable for the sea will become key technologies. [0003] At present, the units installed in inland wind farms mainly include doubly-fed units and permanent magnet direct-drive wind turbines. Due to the high rated speed of doubly...
