A Soft Control Architecture: Breakthrough in Hard Real-Time Design for Complex Systems

Embedded OEMs – especially those whose products have complex human-machine interfaces, manage many degrees of motion, and require hard real-time – have traditionally relied on field programmable gate arrays (FPGAs) and digital signal processors (DSPs) to meet precision and performance requirements.

Metal Bellows - Key Enabling Technology for a Wide Range of Engineering Applications

Convert pressure, mechanical, vacuum and temperature changes into linear or rotational motion using metal bellows. It may be the smallest component of an overall machine assembly but it very often plays the most critical role in the functionality of a system. This newest whitepaper from Servometer outlines seven key enabling technologies that benefit from bellows across a wide range of engineering applications – providing a more precise, more reliable or less costly alternative to an existing engineering solution.

Model-Driven Innovation in Machine Design

This whitepaper discusses a Model-Driven Innovation process, an approach that makes a multidomain, system-level model the core of design activities, allowing engineers to see how individual subsystems work together. With this approach, problems can be fixed early without project delays, and designs can be validated with access to the underlying mathematics, allowing organizations seeking to mitigate system complexities to improve their ability to control costs, produce high-quality designs and move products to market more quickly. Using tools like MapleSim, the multidomain system modeling tool from Maplesoft, enables engineers to develop and test high-fidelity virtual prototypes of their complex dynamic systems.

How to Prevent Step Losses with Stepper Motors

While stepper motors are an excellent solution for many applications, a key concern is step losses. However, in most instances step losses can be prevented or corrected. It is important to remember that a stepper motor does not operate like a DC motor. This white paper from MICROMO engineers provides guidance to determine step losses or non-operation across a variety of applications.
