Problems solved by technology

[0003] The existing motor stator silicon steel sheet is punched into a circular ring, with a number of embedding slots evenly distributed on the inner circle, and six dovetail slots with openings facing outwards evenly distributed on the outer circle, and a circular hole slightly larger than the diameter of the rotor is formed inside. , when the silicon steel sheets are stacked, each round hole forms a cylindrical space, in this space, the gap between the rotor and the stator is easy to form sparks, which poses a safety hazard
[0004] The existing silicon steel sheets cannot effectively prevent electromagnetic waves and cannot meet the needs of customers

Abstract

The invention relates to a weather-resisting silicon steel sheet with high safety. The weather-resisting silicon steel sheet comprises a ring-shaped silicon steel sheet body (1), wherein two sides of the inner side of the silicon steel sheet body (1) are each provided with two wire-winding support feet (2), the inner sides of each pair of two wire-winding support feet (2) form an oval rotor space, positioning grooves (3) are formed in upper and lower sides of the silicon steel sheet body (1), a bump (4) is arranged in each positioning groove (3), the silicon steel sheet body (1) is further provided with buckling blocks (5), and the surfaces of the silicon steel sheet body are coated with an anti-electromagnetic coating. The weather-resisting silicon steel sheet with high safety has the advantages of being high in safety, generates not sparks in the clearance between a rotor and a stator, is convenient in manufacturing, and can effectively prevent electromagnetic interference.

Description

technical field [0001] The invention relates to a silicon steel sheet. It belongs to the field of electromechanical technology. Background technique [0002] Silicon steel sheets for electrical purposes are commonly known as silicon steel sheets or silicon steel sheets. It is a silicon-iron soft magnetic alloy with extremely low carbon content, generally with a silicon content of 0.5-4.5%, and is made by hot and cold rolling. Generally, the thickness is less than 1mm, so it is called thin plate. Adding silicon can increase the resistivity and maximum permeability of iron, and reduce the coercive force, core loss (iron loss) and magnetic aging. It is mainly used to make iron cores of various transformers, motors and generators. [0003] The existing motor stator silicon steel sheet is punched into a circular ring, with a number of embedding slots evenly distributed on the inner circle, and six dovetail slots with openings facing outwards evenly distributed on the outer ci...
