The invention discloses an inner-ventilation vertical-shaft wind-driven generator of a permanent-magnet superposing type, belonging to the technical field of new-energy power supply system equipment and comprising magnetic steel bodies 3, a static disc 8, coils 9 and a lead 7. The magnetic steel bodies 3 are respectively embedded in a movable disc 1 and a movable disc 2; the static disc is sleevedon a main shaft 5 and supported by a bearing 4 in the movable disc 1; and the coils 9 are embedded in the static disc 8, connected with the lead 7 and led out of the generator. The inner-ventilationvertical-shaft wind-driven generator of a permanent-magnet superposing type is characterized in that an inner ventilating device is arranged in the generator and the generator is integrally arranged with a shell, and the generator comprises the main shaft 5 and an air duct 6 which are made of steel tubes; and air passes through the air duct 6 to take away heat from the inner part of the main shaft5 of the generator so that the problem that temperature rise overhigh heat generated in operation hinders generating capacity and causes demagnetization and aging is solved, the generating efficiency is improved, and the service life is prolonged. The shell-generator integrated arrangement is achieved by directly arranging the bearing 4 on the movable disc 1 and integrating the generator shell,a rotor and an end cover, eliminating an upper end cover, a lower end cover and the generator shell, and reducing generator parts. The invention has the advantages of easy ventilation, reduced size, lighter weight and lower manufacture price.
Description
technical field [0001] The invention relates to an internally ventilated vertical axis permanent magnet superposition type wind power generator, which belongs to the technical field of new energy, and in particular to a generator in wind power generation equipment. Background technique [0002] In the prior art, the main shaft of the vertical shaft permanent magnet wind power generator is generally made of round steel entity, supported by the bearing in the end cover, assembled with the stator housing in a closed type, and dissipated heat by the generator housing; there is Due to the overheating of the internal temperature of the generator, which restricts the power generation capacity and causes the permanent magnets to gradually demagnetize and age, how to overcome the above shortcomings, reduce costs, and improve wind energy utilization and service life is the purpose of the present invention. Contents of the invention [0003] In view of the above-mentioned problems an...
