Double Differentials – Compact Ultra-High Speed eDrives with Excellent Efficiency
Today’s electric motors for EVs have speeds of 10,000 to 20,000 rpm, with future speeds trending up to 40,000 RPM. This trend requires transmission ratios which are more than 20 times higher than well-known transmissions for vehicles with combustion engines.
The double differential delivers highest ratios and handles the ultra-high input speeds, with an overall efficiency of more than 98%, from input to output. Learn about design configurations and their benefits including energy savings under sporty and stop- and go driving patterns.
This session will be presented live by Prof. Dr. Hermann Stadtfeld, VP of Research and Development Bevel Gear Technology, supported by live translations by Gleason Asia Personnel.
Cylindrical Gear Manufacturing Technology for EV Transmissions
Electrification is a major trend in global automotive manufacturing. eDrive concepts for hybrid and electric vehicles to meet CO2 reduction goals are constantly rethought and refined. To reflect the challenges of this highly dynamic environment, we will discuss the global electrification trends and latest developments and requirements for eDrive and hybrid transmission manufacture. This topic will be presented by Taichiro Ikegaki, Deputy General Manager of Sales at Gleason Asia, as the conclusion of Gleason’s Home/Gear Trainer webinars in Japan.
