Investigation of Innovative Cooling Systems for a Direct Driven Lightweight PMSG for Wind Power Applications
In this paper, different cooling solutions for a permanent magnet synchronous generator used in wind turbines are investigated. Cooling solutions are developed and narrowed down with the help of an evaluation matrix for more detailed consideration.The cooling performance of the solutions was then analyzed in a simulation. In addition, functional samples of the promising solutions were manufactured and measured in a laboratory environment. For verification purposes, two solutions were integrated into the segments of a scaled demonstrator. The cooling solutions significantly reduce the winding temperature of the demonstration generator in comparison to a passive cooling system.
