DVS Examines Key Factors for e-Mobility
Electric drives for vehicles continue to be technically challenging in terms of range, efficiency, and sustainability, among other things.
This means that the mobility of the future is still in the development phase, albeit at a very advanced stage. The stringent requirements of electromobility also increase the requirements on the components, processes, and machinery. DVS is answering these challenges with modular system solutions.
The DVS companies Werkzeugmaschinenbau Ziegenhain (WMZ), Buderus Schleiftechnik, PRÄWEMA Antriebstechnik, and DVS Production developed such a solution for the complete machining of rotor shafts for electric motors, which combines these key factors for future feasibility:
Quality
With comparatively high speeds of 15,000–30,000 rpm, electric drives require much higher quality surfaces, gear teeth, as well as geometrical tolerances. Since both the WMZ machine for soft machining and the Buderus machine for hard-fine machining each provide complete machining processes, the number of clamping processes is much lower, which also lowers the potential for errors.
Even more important for the final quality, however, is the coordination within DVS’s technology toolbox: The tools, processes, and machines in the system are constantly learning from each other from the data generated, which allows them to be optimally adjusted to each other. But not only the data has a say – the specialists in the Group are also communicating continuously and sharing their know-how.
