Segmented magneto-conductive structure applied in rotating machines

Abstract

A segmented magneto-conductive structure applied in rotating machines comprises a rotor assembly and a stator assembly. The rotor assembly includes a rotor yoke component and a plurality of rotor teeth components. The rotor yoke component is made of non-oriented silicon steel. The rotor teeth components are made of grain-oriented silicon steel. The stator assembly includes a plurality of stator yoke components and a plurality of stator teeth components. The stator yoke components and the stator teeth components are made of grain-oriented silicon steel. Thereby, an operational efficiency of a motor applying the segmented magneto-conductive structure is enhanced.

Description

technical field [0001] The invention relates to a segmented magnetic conduction structure applied to a rotating electrical machine, in particular to a segmented magnetic conduction structure using directional silicon steel materials. Background technique [0002] Facing the cruel reality of the increasing shortage of global petrochemical energy, major industrial countries have attached great importance to the regulation of energy development and utilization. Taking the field of home appliances as an example, more than 40% of the total household power consumption is used in indoor air conditioners, refrigerators, heat pump water heating systems and fans. Taking the industrial and commercial field as an example, more than 70% of the power consumption is used in motor equipment such as air compressors, vacuum pumps, water pumps, transmissions, central air conditioners, supply and exhaust fans, refrigerating machines, and heat pumps. Therefore, improving the use methods of vari...

However, almost 97% of the production capacity of rare earth permanent magnets comes from mainland China, and due to the large-scale use of rare earth permanent magnets in recent years, the price of rare earth materials has soared due to the imbalance between supply and demand, and it has also affected the application of permanent magnet motors And the price of the motor product or equipment driven by the permanent magnet motor

[0004] In view of this, international manufacturers that mainly develop high-efficiency energy-saving equipment and products have hidden concerns about the use of rare earth permanent magnets
