Integral permanent magnet ring embedding self-location permanent magnet structure

Abstract

The invention relates to an integral permanent magnet ring embedding self-location permanent magnet structure, belonging to electrical category, and consists of an upper cap, an upper cover, an inner magnet yoke, an integral permanent magnet, an outer magnet yoke, a coil, a lower cover and an output shaft; an integral permanent magnet ring consists of an integral permanent magnet ring outer ring,the permanent magnet and an integral permanent magnet ring inner ring, wherein the permanent magnet is assembled between the permanent magnet ring inner ring and the permanent magnet ring outer ring to form a whole permanent magnet ring structure; the permanent magnet comprises at least one or a plurality of magnetic flaps; when in installation, the integral permanent magnet ring is assembled on the outer magnet yoke by a specialized fixture for primary location, and then the integral permanent magnet ring is pushed into the working position by the inner magnet yoke through external force; and the whole process is adjusted and located completely by the structure and the dimensional accuracy of parts, and zero air gap full contact can be realized. The integral permanent magnet ring embedding self-location permanent magnet structure lowers the difficulty of complete machine processing and assembling, reduces the cost, leads the product to maintain maximized magnetic force, ensures the product to be stable and reliable for a long time, and is suitable for mass production and streamlined operation.

Description

technical field [0001] The invention relates to electricity, in particular to an integrated permanent magnet ring embedded self-positioning permanent magnet structure. Background technique [0002] In the current power supply electrical industry, there are mainly two technical solutions for the design and manufacture of permanent magnet structures. One is: firstly, the multiple permanent magnet flaps are attracted to the positioning surface of the outer magnet yoke one by one, then the inner magnet yoke is placed inside the permanent magnet flap, and finally the outer magnet yoke, the permanent magnet flap, and the inner magnet After the yoke is bonded into one body, it forms a magnetic channel with the moving iron core; the other is: firstly, a plurality of permanent magnet lobes are attracted to the supporting surface of the outer yoke one by one, and then the inner yoke is designed as a shoulder with a positioning surface structure, and set it on the inner side of the pe...
