Description

Technical Field

[0001] The utility model relates to the field of rotors, in particular to a novel rotor iron core. Background Art

[0002] The rotor core mainly involves the field of motor technology, especially the rotor part of the motor. The motor is a device that converts electrical energy into mechanical energy and is widely used in various mechanical equipment. The rotor core is an important component of the motor. It interacts with the stator to generate a rotating magnetic field, thereby driving the rotor to rotate.

[0003] In the existing rotor core, the motor may be more susceptible to wear, corrosion and thermal stress during high-speed operation, thereby shortening its service life. In addition, the current is unevenly distributed and chaotic, which increases energy loss and affects the performance and life of the motor. Therefore, technical personnel in this field provide a new rotor core to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a new type of rotor core is proposed. By adopting an insulating layer, a protective coating and an anti-corrosion layer, the insulating layer prevents the current from running wildly, the protective coating reduces friction and wear, and the anti-corrosion layer resists erosion by corrosive media, thereby protecting the rotor core in all directions and extending its service life. The magnetic force generated by the magnet causes the adjacent rotor core bodies to generate adsorption force. At the same time, the precise positioning connection of the protrusions and grooves enhances the stability of the connection, reduces the looseness and displacement caused by vibration during operation, and improves the reliability of the motor operation. The material of the rotor core body is stainless steel, which not only provides higher magnetic conductivity to optimize the motor magnetic field distribution and improve efficiency, but also has good corrosion resistance and wear resistance, and has excellent comprehensive performance. In addition, the protective layer effectively reduces the electromagnetic loss and noise during the operation of the motor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel rotor core, comprising a plurality of rotor core bodies, wherein the plurality of rotor core bodies are arranged in an up-and-down arrangement, the outer side walls of the plurality of rotor core bodies are provided with a protective layer, the outer side walls of the protective layer are provided with a plurality of teeth arranged in an annular manner, the one side ends of the plurality of teeth are provided with a pole shoe, the inner side walls of the plurality of rotor core bodies are provided with a protective structure, the plurality of rotor core bodies are provided with a connecting structure, the center of the upper end surface of the rotor core body is provided with a plurality of through holes arranged in an annular manner, and the center of the upper end surface of the plurality of protective structures is provided with a connecting groove;

By generating magnetic force with magnets, an adsorption force is generated between adjacent rotor core bodies. At the same time, with the precise positioning connection of bumps and grooves, the stability of the connection is enhanced, reducing looseness and displacement caused by vibration during operation, and improving the reliability of the motor operation. By selecting stainless steel as the material of the rotor core body, it not only provides high magnetic conductivity to optimize the motor magnetic field distribution and improve efficiency, but also has good corrosion resistance and wear resistance, with excellent comprehensive performance.

At the same time, the bumps cooperate with the corresponding grooves. When adjacent rotor core bodies are connected, the bumps can be embedded into the grooves to achieve precise positioning and connection. The adsorption force provided by the magnets enhances the stability of the connection between adjacent rotor core bodies, reducing looseness and displacement caused by vibration and other reasons during operation.

[0011] Further, the plurality of bumps are respectively adapted to the plurality of grooves;
