Embodiment Construction

[0012] In order to further understand the features and technical content of the present invention, please refer to the following detailed description and drawings related to the present invention. However, the drawings are provided for reference and illustration only, and are not intended to limit the present invention.

[0013] Such as figure 1 As shown, the segmented yoke structure of the synchronous AC motor of the present invention includes two parts of the shaft 1 and the yoke 2 . The shaft 1 includes the yoke matching section 1.2 and the shaft shoulder 1.1. The yoke matching section 1.2 is a segmented structure, and the diameter of each adjacent section differs by 2mm, decreasing from left to right, and its total length is at least longer than the yoke 2. Out of 10mm, the length of each yoke matching section 1.2 is about 300mm, and the specific length depends on the total length. The left side of the yoke fitting section 1.2 is a shaft shoulder 1.1, and the diameter of ...

Abstract

The invention provides a sectional magnetic yoke structure of a synchronous alternating-current motor, which comprises a shaft and a magnetic yoke. The shaft comprises a magnetic yoke matching section and a shaft shoulder, the magnetic yoke matching section has a sectional structure, the diameter of each unit of the magnetic yoke matching section is reduced sequentially from left to right, the total length of the magnetic yoke matching section is larger than that of the magnetic yoke, the shaft shoulder is arranged on the left of the magnetic yoke matching section, and the diameter of the shaft shoulder is larger than that of the magnetic yoke matching section. The magnetic yoke has a sectional structure formed by welding a plurality of magnetic yoke plates and is sleeved on the magnetic yoke matching section of the shaft, and the left end of the magnetic yoke is butted to the shaft shoulder. The invention further provides a sectional magnetic yoke processing method of the synchronousalternating-current motor. The section magnetic yoke structure is simple and compact and evident in action effect. Processing and assembling are simpler and more convenient, manufacturing cycle is shortened and manufacturing cost is reduced by changing the magnetic yoke on the premise without changing the electromagnetic design.

Description

technical field [0001] The invention relates to a magnetic yoke and a processing method thereof, in particular to a segmented magnetic yoke structure of a synchronous AC motor and a processing method thereof. Background technique [0002] At present, the yokes of large synchronous AC motors generally adopt the installation method of heat-fitting shafts, that is, the yokes are heated and put on the shafts. Because the existing magnetic yoke adopts a whole forging, the magnetic yoke itself is relatively long, and it is very cumbersome to process and assemble, prolonging the manufacturing cycle, making the forging more expensive, and the manufacturing cost is also very high. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a segmented magnetic yoke structure and its processing method which can make the assembly easier and can use cheap common steel plates to reduce the cost. [0004] Technic...
