Alumina ceramics have been used to make motor shafts for decades, but in recent years, zirconia motor shafts have become a new trend.

Compared to metal ceramic shafts, zirconia ceramic shafts have the following advantages：

1. High hardness and wear resistance

Ceramic materials have high hardness and excellent wear resistance, which can effectively reduce friction between bearings and shafts, reduce energy loss, and extend the service life of motors. In addition, ceramic shafts are durable and have a long service life, reducing maintenance and replacement costs。

2. Low friction coefficient

Compared with metal shafts, ceramic shafts have a low coefficient of friction, reduced friction between the shaft and bearings, lower friction torque, and can reduce wear and energy consumption. In addition, low friction coefficient significantly improves the performance of motors with high requirements such as high speed and high frequency。

3. Strong corrosion resistance

Ceramic shafts have excellent corrosion resistance and can be used for a long time in harsh environments such as acid and alkali. The use of ceramic shafts in motors can effectively improve their resistance to special environmental conditions and expand their applicability.

4. Good insulation performance

The insulation performance of ceramic shafts is excellent, which has a good effect on motor applications that require electrical isolation. The application of ceramic shafts in motors can effectively reduce the risk of motor leakage, improve the reliability and safety of motors
