Description
The aim of the joint project is to develop the competitive electric machine of the future. To this end, product and process innovations along the entire value-added chain are being considered.

Challenge
Electrical drives convert electrical energy into mechanical energy. Because of their environmental friendliness, high efficiency and good availability of electrical energy, they are used in a wide variety of industries and are increasingly replacing combustion engines. Demands for higher power density and shorter delivery times require new approaches to the design and manufacture of electrical machines.
Objective
The overall objective of the project is an end-to-end development of the electric drive of the future. This includes the digital design and automated additive manufacturing of a permanent magnet rotor and components of the stator, i.e. the immovable part of the drive, based on innovative insulation technology. A digital twin forms the framework from development to operation.
Methods
To implement the Industry 4.0 concept, feedback-to-design, digital twin, autonomous manufacturing and smart maintenance will be adapted and linked. Processes for the additive production of permanent magnets and winding components, as well as the necessary joining technology will be developed and prepared for demonstration of feasibility. Oxide-ceramic and ceramic-polymer systems are being investigated as novel, additively manufacturable material systems for high-voltage insulation.
