Design and implementation of a novel rotary micropositioning system driven by linear voice coil motor.

Limited-angle rotary micropositioning stages are required in precision engineering applications where an ultrahigh-precision rotational motion within a restricted range is needed. This paper presents the design, fabrication, and control of a compliant rotary micropositioning stage dedicated to the said applications. To tackle the challenge of achieving both a large rotational range and a compac...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Enhanced laser shutter using a hard disk drive rotary voice-coil actuator.

Rotary voice-coil motors from computer hard disk drives make excellent mechanical shutters for light beams. However, the complexity of the necessary electronic driving circuit can hinder their application. A new design is presented here, using a single integrated circuit originally intended for controlling dc motors. A digital input signal switches a unipolar power supply bidirectionally throug...

Design and Optimization of a Rotary Actuator for a Two Degree-of-Freedom zφ-Module

The paper concerns the design and optimization of a rotary actuator which is applied in a pick-and-place robot. The rotary actuator is part of a zφ-module and provides ±180°rotation. The rotor of this actuator is attached to a linear actuator which offers a z-motion of ±5 mm. In the paper, the optimal combinations of magnet poles and coils are determined for this slotless actuator with concentr...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
