   Acceleration Sensors in High-Bandwidth Servo Control
By MUTSCHLER Peter; BAEHR Alexander [View]
[Download]

Abstract: This paper investigates methods to improve servo control performance using acceleration sensors. Several approaches are reviewed, showing their similarities. Design methods and mechatronic aspects are discussed, and a comparison of experimental results is shown.

   First results from an inductor-disk geometry used for electro-magnetic (EM) acceleration of a circuit breaker contact
By ROODENBURG Bart [View]
[Download]

Abstract: The force acting on a workpiece by magnetic fields gained more interest due to new applications. These techniques are used for decades to accelerate or move objects, for instance for fast opening circuit breakers. This contribution describes an electro-magnetic drive system, which accelerates a circuit breaker contact for a DC hybrid switch. During the opening movement an average acceleration of ~19,000 m·s−2 has been realised and the first 4 mm of contact separation is reached after ~422 µs, which is enough to withstand the rated switch voltage of 3 kV.

   HIGH ACCURATE POSITION CONTROL OF AN HYBRID DRIVEN CIRCUIT BREAKER
By POULLAIN Serge; DUPRAZ Jea; COURBON Eric; THOMAS Jea; LUESCHER Robert [View]
[Download]

Abstract: Position control of a hybrid driven circuit breaker is presented. Hybrid drive is the association of an accurate servo controlled motor and a reliable spring operating mechanism. High accurate position control of the circuit breaker contacts is performed through high dynamic torque control of the motor. Both simulation and experimental results highlight excellent performances.

   Optimal design considerations for a linear actuator with active magnetic suspension
By LARO Dick; LOMONOVA Elena; VANDENPUT Andre; LEBEDEV Anton [View]
[Download]

Abstract: The paper describes the detailed analysis that encompasses the magnetostatic design methodology of a linear electromechanical actuator. The actuator itself is a complex electromechanical system combining features of the active magnetic bearing (suspended mass in the order of 0.3 kg) and the linear Lorentz actuator (long stroke range – 50 mm). The basic design considerations are described and the tasks of the magnetostatic design are defined. The analysis and selection of the magnetic materials are carried out. A parametric search with respect to main design variables is performed. It has highlighted several peculiar features of the actuator performance, such as a strong long stroke position dependence of the suspension force and a cross-coupling between the suspension and the propulsion directions. A design procedure leads to modifications in dimensions and coils arrangement. The initial and the improved prototypes are compared on the basis of the finite element method (FEM) modeling and the measurement results, showing significant improvements in performance.
