Development of Magnetic Reluctance Actuators for Vibration Excitation

The development and application of electromagnetic reluctance actuators for vibration excitation are presented. Main advantages are a compact and robust design with low thermal losses. The paper proposes a polarized actuator topology and describes the design procedure. An analytical method based on magnetic networks allows for a fast determination of machine parameters. finite element computations are carried out for a detailed magnetic circuit design. The combination of both methods leads to a straightforward development process for controlled reluctance actuators.
