Investigation into the impact of geometric parameters on cogging torque and efficiency in brushless DC motors has highlighted significant considerations for motor design. Cogging torque, a crucial factor in the performance of brushless DC motors, arises from the interaction between the permanent magnets and the slots of the stator, leading to variations in angular speed and torque ripple.

PEM Aachen GmbH has embarked on a research initiative to develop an Axial-Flux Motor that operates without the use of rare-earth magnets. The project, named AxFea, is supported by the German Federal Ministry for Economic Affairs and Climate Action (BMWK) and involves multiple stakeholders. Current electric vehicle motors heavily depend on rare-earth magnets, which are not only expensive but also…
