Sprache des Tagungstitel:
Electric motors are increasingly used in automotive applications, covering a variety of functions ranging from small actuators to traction motors. In many cases, these motors replace hydraulic systems or systems that are driven directly by the engine, to reduce the carbon emission of cars. The most important design requirements are high power density, low weight, and costeffectiveness. Rare-earth magnets are often the magnetic material of choice for achieving compactness, but supplies of the raw materials from which these are made are, like those of copper, limited. Thus, there is an imperative to minimize the resources required to realize a high-performance motor.A software tool that makes multi-objective optimization of electric motors possible will be introduced. With this tool the trade-off between efficiency and material or manufacturing costs can be analyzed. Examples of optimized motors for automotive applications using rare-earth magnets are presented. Additionally, alternative motor topologies such as synchronous reluctance machines and machines with buried ferrite magnets are compared.
