PO439: Mechanical test setup for a novel high-torque density generator topology
Jingjing Luo, Senior Engineer, Fraunhofer IWES
Abstract
This paper presents the design and development of a mechanical test setup for a novel high-torque density generator topology aimed for wind energy applications. The generator’s innovative electromagnetic design increases torque density while maintaining high efficiency, which could lead to higher electrical output and significant critical raw material savings in turbine drivetrains. Its compact axial length represents a disruptive departure from conventional topology, offering a potential shift in generator architecture and targeting a significant lower environmental impact. In this context, Fraunhofer IWES is responsible for developing procedures for the validation and testing of novel-topology direct-drive generators of these characteristics. Within a current research project, the intention of the mechanical test setup focuses on validating performance parameters, including torque transmission, thermal behavior, and oscillation responses, assessing the generators under actual field conditions. In this manner, the setup will enable an accurate assessment of the generator's performance. This setup aims to validate the generator’s functionality and performance, with the objective of demonstrating the technology’s potential for MW-scale wind turbine applications. It also plays a critical role in advancing the technology readiness level (TRL) of the generator, moving it closer to integration into next-generation wind turbines. Through mechanical testing and data analysis, the insights gained will enhance simulation models, address potential mechanical and thermal challenges, and guide design optimization. The outcome of this testing will help to demonstrate, through simulations and machine tests, that a torque density of approximately 70 Nm/kg can be achieved for a 2 MW scale of this kind of generator. This will provide valuable insights for the next phase of the project, helping to develop a generator model that reduces costs and material use, while maintaining high efficiency in wind energy systems.
