Design aspects of a linear reluctance actuator used as shaker in vibration test rigs are presented. The bidirectional trajectory tracking device provides forces up to 10 kN and a stroke range of 7 mm. Key features for high performance and robust operation are a polarized topology and strong armature springs. Core and armature lamination ensure high actuator dynamics. Experimental results with a prototype device confirm the presented methods and design aspects. The main advantage compared to conventional shakers are a high force density and energy efficiency.
