Abstract

The invention relates to an anti-electromagnetism wind power generator rotor, and the rotor comprises a stator body. The stator body is formed by the continuous lamination of a plurality of silicon steel sheets (1). The silicon steel sheets are respectively of an annular structure with a central hole (2). The rotor is characterized in that the annular regions of the silicon steel sheets (1) are respectively provided with 3-6 fan-shaped grooves (3); each annular region between the adjacent fan-shaped grooves (3) is provided with an installation hole (4); the surfaces of the silicon steel sheets (1) are coated with anti-electromagnetism coating layers. The annular regions of the silicon steel sheets (1) are respectively provided with 3-6 fan-shaped grooves (3), thereby reducing the weight of the rotor, and enabling the energy conversion efficiency to be higher. Moreover, the rotor has an anti-electromagnetism function.

Description

technical field [0001] The invention relates to an anti-electromagnetic wind power generator rotor, which belongs to the technical field of electromechanical. Background technique [0002] A wind turbine consists of a nose, a swivel, an empennage, and blades. Every part is very important, and the functions of each part are: the blades are used to receive wind force and convert it into electrical energy through the nose; the empennage makes the blades always face the direction of the wind to obtain the maximum wind energy; The function of the empennage to adjust the direction; the rotor of the nose is a permanent magnet, and the stator winding cuts the magnetic field lines to generate electric energy. The traditional anti-electromagnetic wind turbine rotor is formed by stacking and pressing multiple solid silicon steel sheets. Since the rotor keeps rotating during operation, the solid silicon steel sheet rotor is too bulky and the energy conversion efficiency is low. [000...
