   A New Linear Induction Motor Utilizing a Parametric Oscillation
By S. Kikuchi; K. Ishikawa [View]
[Download]

Abstract: A new type of a linear param etric m otor is proposed in this paper. The construction and the basic characteristics of the linear motor are discussed. It is clarified that static thrust Fs increased significantly.

   An Electromagnetic Contactor with Large Voltage Range: a Comparative study of different converter topologies
By P. J. Santos; J. F. Silva; A. J. Pires [View]
[Download]

Abstract: A comparative study of three suitable power electronic converter topologies is made in order to feed an electromagnetic contactor, increasing the command voltage range. It is intended to use a unique coil for most usually commercial voltages available, with economical benefits, regarding production and stock costs. DC and AC inputs are allowed. A comparison among the different topologies is done, regarding the input-output voltage relationship and the system power losses. The control system is presented using sliding mode control theory and evolving the converter topology with best performance.

   Design of a Single-Phase Reluctance Actuator with Large Linear Stroke
By D. Gerling [View]
[Download]

Abstract: The design of a single phase rotary reluctance actuator with internal spindle thread is presented, where this internal thread transforms the rotation into a linear movement. The main parts of the design procedure are: a) a mechanical calculation of the spindle thread, b) an analytical parametric optimization of the reluctance actuator and c) a subsequent refinement using FEM software.

   Dynamic Model of Linear Position Transducer
By J. Corda; J. Al-Tayie [View]
[Download]

Abstract: This paper refers to the dynamic modelling of a novel form of electromagnetic transducer for continuous position sensing. Limitations of commonly used transducer of Linear Variable Displacement Transformer (LVDT) type are addressed and an alternative, also contactless, transducer based on reluctance variation is discussed with emphasis on its mathematical model which accounts for the effects of magnetic core losses and motional e.m.f. on the output of the sensing elements.
