Abstract

The invention discloses a reconstructible motor stator winding detection apparatus for remanufacturing. The apparatus comprises a test assembly connected with a stator winding for detecting winding parameters, a clamping assembly for fixing a stator and a loading assembly for increasing a load for the stator winding. The loading assembly comprises a rotor and a motor driving the rotor to rotate, the rotor comprises a core column, one end of the core column is provided with a plurality of rotor windings, the rotor windings are sector magnetizers wound with coils, the upper ends of the plurality of rotor windings are provided with soft iron pieces synchronously rotating with the rotor, the soft iron pieces comprise sector portions in one-to-one correspondence with the rotor windings, the upper surfaces of the sector portions are curved surfaces enabling the thicknesses of the sector portions to be gradually decreased from a circumference to a circle center, the core column is externally sleeved by slip rings, the coils of the plurality of rotor windings are connected with the slip rings, a rotation axis of the rotor is vertical to a clamping plane of the clamping assembly, and the soft iron pieces are disposed at the center of the stator winding. The apparatus can perform rapid reconstruction for different motor stator windings and completes detection, and is high in work efficiency.

Description

technical field [0001] The invention relates to a stator winding detection device, in particular to a remanufacturing-oriented reconfigurable motor stator winding detection device. Background technique [0002] The motor is the core of electromechanical energy conversion. It plays an important role in the production, transmission, distribution of electric energy, the drive of mechanical devices, and the execution of control systems. It is commonly used in industry, agriculture, transportation, national defense engineering, and daily life. important equipment. At the same time, with the continuous improvement of material living standards, more motors are equipped in various equipment to achieve automation and convenience, which makes the application of motors more extensive and makes the forms of motors more diversified. Models tend to be diversified. [0003] However, as all kinds of equipment continue to reach the end of their life, a big problem that needs to be faced is...

AI Technical Summary

Problems solved by technology

If only the conventional static detection method is used, since the winding coils are in different states under no-load and loaded conditions, the temperature of the winding will rise when it is loaded, and it will expand itself, and its internal defects will become more apparent. , or even more serious, therefore, pure static inspection will not be able to have a correct evaluation of the damage of the waste stator winding

At the same time, there are many types of scrapped motors, and the disassembled stators will have various sizes. If different detection devices are designed for different motor stator windings, the cost will be greatly increased.
