Rotating assembly

Abstract

The invention discloses a rotating assembly which comprises a stator and a rotor. The inner wall of the stator is provided with a plurality of projections. Each projection comprises a connecting partand a contacting part. The width of the connecting part gradually increases in an inward direction along the radial direction of the stator. The contacting part comprises a blocking part. Two adjacentprojections form a trough which is internally provided with a winding. The rotor comprises a guiding strip and end rings which are arranged at two sides of the guiding strip. The end rings at two sides are respectively provided with a fan balde. The rotor further comprises an iron core. The iron core is provided with a plurality of oblique troughs in the circumferential direction. An included angle between the oblique trough and the iron core is smaller than 45 DEG. The width of the cross section of the oblique trough gradually reduces inwards along the radial direction of the iron core. Theguiding strips are arranged in a shape of penetrating the oblique troughs. The guiding strips and the oblique troughs are in one-to-one correspondence. Through adjusting the shapes and angles of the projections in the stator and the oblique troughs in the rotor, a squirrel-cage rotating assembly has advantages of reducing cost through using an aluminum material as the material of the winding and the guiding strip, and improving working efficiency of the rotating assembly.

Description

Technical field [0001] The invention relates to a rotating assembly. Background technique [0002] In the squirrel-cage motor, because there is a closed single-phase coil on the left and right of the rotor, there is no need to install the rotor winding, and the structure is simple. In actual use, because the guide bar is used as a component to replace the winding, copper bars are usually used as raw materials In the small and medium-sized squirrel cage type point concentration, if the guide bars are all made of copper as the raw material, the cost increase will be greater, because people choose cheaper aluminum as the material of the guide bar, but when aluminum is used as the guide bar, the motor’s The overall operating condition is not as good as that of copper. Therefore, it is necessary to design a squirrel cage type rotating assembly structure that can save costs and improve efficiency. Summary of the invention [0003] The present invention aims to solve the above-mentioned...

Problems solved by technology

[0002] In the squirrel-cage motor, since the rotor has a closed single-phase coil on the left and right, there is no need to set the rotor winding, and the structure is relatively simple. In the actual use process, since the guide bar is used as a part to replace the winding, copper bars are usually used as raw materials. , in small and medium-sized squirrel-cage points, if copper is used as the raw material for the guide bars, the cost will be greatly increased, because people choose cheaper aluminum as the material of the guide bars, but when aluminum is used as the guide bar, the motor’s The overall operation is not as good as copper, so it is necessary to design a squirrel cage rotating assembly structure that can save costs and improve efficiency
