NTN Unveils Revolutionary Resin Mold Insulated Bearing for EV Powertrains at Yokohama Expo 2024
NTN Unveils Revolutionary Resin Mold Insulated Bearing for EV Powertrains at Yokohama Expo 2024 - NTN's Resin Mold Technology Tackles EV Bearing Challenges
NTN's Resin Mold Insulated Bearing marks a significant leap in EV powertrain technology, addressing the persistent issue of electrical pitting in eAxles.
The injection-molded insulated resin layer on the bearing's outer diameter offers superior protection against high-frequency currents, potentially revolutionizing the durability and efficiency of electric vehicle components.
This innovative approach could lead to more compact and robust EV designs, paving the way for the next generation of high-performance electric vehicles.
The injection-molded insulated resin layer on the bearing's outer diameter is a mere fraction of a millimeter thick, yet it provides significant protection against electrical pitting, a common issue in EV powertrains.
NTN's resin mold technology allows for precise control of the insulation layer's thickness, achieving a variance of less than 5 micrometers across the bearing surface.
The new bearings can withstand voltage differentials up to 1000V, which is crucial for high-performance EVs utilizing 800V systems.
Testing has shown that these insulated bearings reduce energy loss by up to 15% compared to traditional bearings in EV applications, potentially extending vehicle range.
The resin mold process integrates seamlessly with existing bearing manufacturing lines, allowing for scalable production without significant retooling costs.
NTN's bearings with this technology have demonstrated a 30% increase in lifespan during accelerated wear tests, potentially reducing maintenance intervals for EV powertrains.
