Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] see figure 1 , a squirrel-cage rotor in the illustration, including a guide bar 2 and a right end ring device 4, three guide bars 2 are equidistantly installed on the inner wall of the right end ring device 4, and the stator current is suppressed by the structure of the squirrel-cage rotor.

[0019] see Figure 1-2 , the end of the guide bar 2 away from the end ring device 4 is fixedly installed with a left end ring device 1 for positioning and clampin...

Abstract

The invention discloses a squirrel-cage rotor, and the rotor comprises guide bars and a right end ring device; three guide bars are equidistantly mounted on the inner wall of the right end ring device, and a left end ring device for positioning and clamping the guide bars is fixedly mounted at one end, far away from the right end ring device, of each guide bar. A centrifugal elastic flow guide flow dividing device is movably installed at the position, corresponding to the guide bar, of the inner wall of the left end ring device. According to the squirrel-cage rotor, the damage to electronic elements in the squirrel-cage rotor due to the fact that starting current is too large can be improved conveniently, the service life of the squirrel-cage rotor is prolonged, and use safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rotors, in particular to a squirrel cage rotor. Background technique [0002] The squirrel-cage motor is a kind of three-phase asynchronous motor, and the squirrel-cage rotor is the rotating part of the squirrel-cage motor. Generally, a copper or aluminum rotor coil is cast in a cage-shaped slot on the rotor core. The coil is a closed loop that is not connected to other parts, and its main function is to suppress the stator current. [0003] Existing squirrel-cage rotors cause damage to the electronic components inside the squirrel-cage rotor due to excessive current at the start of the squirrel-cage rotor, which reduces the service life of the squirrel-cage rotor and reduces the user experience of the user. Therefore, we propose a squirrel-cage rotor cage rotor. Contents of the invention [0004] The purpose of the present invention is to provide a squirrel-cage rotor that improves the safety of use ...
