Title: Solution to Shaft Voltage and Bearing Corrosion Issues

Introduction: We are pleased to announce the release of our new model by a leading company. The vehicle was introduced in 2020 and faced significant bearing electrical corrosion problems towards the end of 2021. Customers reported complaints regarding bearing and motor abnormal noises. Initially, the proposed solution was to install conductive oil seals, but they failed within a week. The motor's initial design did not consider these issues, and there was no space available for installation.

Solution: After extensive verification with our technical team at Cheng Technology, we have successfully modified the design. The previously circular conductive element has been restructured into a rod-like shape, extending into the hollow cavity of the rotating shaft. This modification allows the conductive element to come into contact with the inner wall, effectively dissipating the electrical charge. As a result, the shaft voltage has been reduced from over 20V to below 5V.

Another new brand by a leading company initially measured a shaft voltage of only 5-6V. Some may consider this voltage level safe. However, in terms of discharge waveform, lower voltage indicates a lower discharge threshold, resulting in an extremely thin oil film that cannot withstand higher voltages. This situation presents a higher risk. By implementing the Bearing Protection Core®, the shaft voltage can be reduced to approximately 1V.

It is crucial to note that there is an inherent potential difference between both ends of the shaft. Sometimes, this potential difference exceeds the bearing oil film's capacity. If one end of the motor is equipped with a conductive ring while the other end lacks any measures, the voltage from the rotating shaft will accumulate on the oil film of the other end. This accumulation accelerates the formation of circulating currents. To address the risks associated with voltage on both ends of the shaft, we propose a solution involving insulated bearings on one end and conductive rings on the other end. This approach aims to block the circulating current and dissipate the harmful energy. Alternatively, both ends can be fitted with conductive rings, allowing the current to pass through the rings rather than circulating through the bearings. The drawback of this solution is a slight amount of circulating current within the shaft, but the magnitude is relatively small.

Conclusion: Currently, shaft voltage issues are prevalent, especially with 800V systems, making it crucial to implement appropriate measures. Our Bearing Protection Core®, developed by Cheng Technology, has been extensively tested in both laboratory and practical applications, effectively resolving shaft voltage and bearing corrosion problems.
