Problems solved by technology

However, this method will have certain problems in practical applications. First, the silicon steel core and the amorphous iron core are unevenly distributed in the axial direction, which may easily cause wear of rotating parts such as bearings due to uneven radial electromagnetic force distribution when the motor rotates at high speed. Problem; secondly, the alveolar structure of the waste silicon steel core is designed according to the electrom...

Embodiment

[0059] In this embodiment, the method for making the amorphous-silicon steel composite iron core for radial field motors using the method of the present invention is the same, only need to use different composition systems or different grades of amorphous or nanocrystalline thin strip materials Different amorphous-silicon steel composite stator cores can be prepared by replacing and selecting different process parameters according to the properties of different amorphous or nanocrystalline thin strip materials. Therefore, in the following, the stator core of a radial magnetic field motor is prepared by compounding non-oriented silicon steel with the grade of B35AV1900 and the amorphous strip with the grade of 1k101 as an example, and the specific implementation of the present invention will be further described in detail in conjunction with the accompanying drawings and examples. .

[0060] In this embodiment, the silicon steel strip grade B35AV1900, thickness 0.35mm, and band...

Abstract

The invention discloses an amorphous-silicon-steel composite stator core for a radial magnetic field motor and a manufacturing method thereof. The composite stator core comprises silicon steel plate layers and amorphous alloy plate layers which are alternately stacked and are then solidified into a block body. The manufacturing method comprises steps of composite material roll making, cross cutting and stacking, annealing, paint dipping and solidification, and processing. The core has properties of low loss, high saturation magnetic induction intensity and high mechanical strength.

Description

technical field [0001] The invention belongs to the field of magnetic circuit components of electric motors, and in particular relates to a stator core made of amorphous-silicon steel compound for a radial magnetic field motor and a manufacturing method thereof. The stator core is suitable for applications in the frequency range of 50Hz to 3kHz Radial field motor. Background technique [0002] As the most important power equipment, the motor is widely used and consumes a lot of energy. The electricity consumption of motors in my country is about 60% of the total electricity consumption of the whole society. In 2015, it exceeded 3.3 trillion hours. It can be seen that reducing motor loss and improving motor efficiency is of great significance to energy saving and emission reduction. [0003] Compared with traditional silicon steel materials, amorphous soft magnetic materials have very low loss due to their low coercive force, high resistivity (about 3 times that of silicon s...
