Tiivistelmä
Active magnetic bearings (AMBs) have the potential to be incorporated into various high-speed applications. Owing to the benefits offered such as lubrication-free operation, energy efficiency, reliability, etc. Currently, an AMB is designed with a focus on performance.
Little attention to ease of assembly and manufacturability is given in the design phase. The initiation for this research was laid out to assess the feasibility of applying design for manufacturing and assembly (DFMA) aspects to the design of an AMB.
DFMA would provide improved product in terms of modularity, cost-effectiveness, lower time to market, etc. Possible integration solutions for combining the sensor and actuator of an AMB were also reviewed. This research was conducted using a combination of interviews with firms, literature review, and analysis. New concepts were proposed based on results gained from DFMA analysis and design review carried out on an AMB developed at LUT. A selection matrix was used to find the best solutions. Top-rated conceptual solutions were analysed and the results were compared with those of the original assembly.
It was realised that the accuracy of the results and the amount of data available regarding assembly and manufacturing are directly proportional to each other. The proposed solutions outperform the present structure on the majority of criteria. Therefore, a product design such as AMB can be improved via DFMA. Also, methods using quantitative parameters in future shall provide improved product design with realistic numbers.
