Extreme Condition Verification: Reliability Map of Axial Magneto-Electric Drive
Based on the measured network covering 28 provincial administrative regions across the country, the cumulative completion of the hub electric drive axle is as follows: ① There has been no overheating record for 800 consecutive hours under heavy load conditions in Shanxi coal mines (with a maximum slope of 12%). ② In the sandy and windy environment of Tacheng, Xinjiang (PM10≥800μg/m³), the dust filtration system has zero faults. ③ In the high salt spray corrosion environment around Hainan Island (with an average annual RH≥85%), the anti-corrosion grade of key components reaches IP6K to 9K. The most stringent Mohe extreme cold test (-42℃) shows that its self-developed low-temperature preheating system can raise the motor temperature from -40℃ to the working threshold of -10℃ within 18 minutes, with a cold start success rate of 99.3%. These data support the milestone of 3 million kilometers without major repairs, with a failure interval (MTBF) of 150,000 kilometers, which is 2.3 times higher than that of traditional electric drive systems.
