Abstract
The utility model provides a magnetic suspension weight and friction reducing vertical axis aerogenerator, which consists of a wind wheel and a generator provided with a stator, a rotor and a generator, wherein, a stator permanent magnet and a rotor permanent magnet are respectively fixed on the stator and the rotor; the stator permanent magnet and the rotor permanent magnet are arranged symmetrically one above the other, and the polarities of the two sides facing each other are the same; the stator permanent magnet is arranged below the rotor permanent magnet. The repulsive force of the rotor permanent magnet and the stator permanent magnet counteracts the downward pressing force of the wind wheel; as the suspension function does not produce friction, the start-up performance of the generator is good, the efficiency is high, the load of the bearing components is reduced, and the materials are saved; the rotor permanent magnet and the stator permanent magnet are arranged in the generator, thereby the structure is compact. The gap between the bottom shaft shoulder of the generator shaft and the top end face of the inner ring of the lower bearing or the gap between the top shaft shoulder of the generator shaft sleeve and the bottom end face of the inner ring of the upper bearing avoids the contact of the rotor permanent magnet with the stator permanent magnet and protects the permanent magnets.
