New energy motor shaft quality judgment and selection of four methods
Four methods to judge the shaft quality of new energy motor:
First, look at motor shaft technology
Check whether the surface treatment of the motor shaft is smooth and flat. Generally good quality shaft technology is more perfect. The appearance should be free of burrs and black patches on the coating. When the shaft is closed, whether the torque is uniform or not, the life is directly affected by the non-uniformity. This also directly indicates the level of shaft factory technology manufacturing.
Two, look at the motor shaft material
Shaft is the finished structural parts used more times, therefore, the selection of materials, easy to rust become an important basis for the quality judgment of shaft. The common motor shaft is made of imported SK7, stainless steel, which has high wear resistance and can improve the anti-corrosion function of the motor shaft. The ordinary motor shaft is made of inferior stainless steel, or it is sold in the manufacturing process, and the motor shaft is rusted in use
3. Measure the experimental data of the motor shaft
Both methods determine the quality of the motor shaft primarily through the surface, and directly determine the quality of the motor shaft through the experimental data. The motor shaft usually uses good material and excellent technology. The life test of the motor shaft reaches about 3W times, and the torque attenuation rate is within 20%. On the contrary, usually poor quality motor shaft life is short, in use may occur easy to break phenomenon.
Motor shaft plays a great role, the shaft selection is not good will directly affect the product life and use experience. Therefore, consider the following points when planning to purchase a shaft.
Four, new energy motor shaft optional points for attention:
1. Understand the qualification, economic strength and pre-sales and after-sales service of the motor shaft factory. Avoid unnecessary trouble
2. Test report and environmental protection report are required to ensure that the quality of the shaft meets the requirements for use.
3, clear choice of shaft use requirements, choose the right price is not the higher quality, reduce unnecessary waste.
