Myth #6: “Electric cars deliver less performance”
Less engine noise doesn’t automatically mean less performance. Electric motors can deliver high torque, enabling dynamic acceleration.
One important component of the electric powertrain is the rotor shaft. As part of the rotor, it transfers torque from the electromagnetic to the mechanical system. Its design therefore has a significant influence on the performance of the powertrain.
The drive specialists at thyssenkrupp Dynamic Components develop and manufacture rotor shafts specifically for electric powertrains. Their multi-part, hollow design also allows additional functions such as cooling to be integrated.
Less noise doesn’t mean less performance. Modern electric powertrains can deliver high torque and correspondingly dynamic acceleration.
Myth #7: “Electric cars make unpleasant noises”
Electric cars are significantly quieter than vehicles with combustion engines. However, this can make other sounds more noticeable. Electric powertrains and their power electronics, for example, can generate high-frequency sounds that may be perceived as unpleasant.
This is where bondal® from thyssenkrupp Steel comes in. The sandwich material consists of two steel sheets with a viscoelastic polymer layer between them and offers sound-damping properties. Studies show potential applications for optimizing acoustics around electric drive motors and their power electronics.
The material can therefore help reduce unwanted noise inside the vehicle and further improve acoustic comfort in electric cars.
The acoustics of electric vehicles can also be specifically optimized – including through specially developed materials such as bondal®.
E-mobility continues to evolve
Many myths surrounding e-mobility stem from concerns that were understandable, particularly in the technology’s early years. Since then, vehicles, charging infrastructure, powertrain technologies and materials have developed significantly.
With materials and components for electric powertrains, battery housings and other applications, thyssenkrupp is helping to make e-mobility more powerful, efficient and safe.
