Motion control systems engineers work chiefly in two well-defined areas: 1) new designs and 2) redesigns or retrofits. This article examines the best approach for each option.
It is a simple fact: better lubrication can lead to dramatic energy savings and an improved bottom line. This ought to interest any plant manager who is looking for ways to reduce operating costs, and it is especially significant at a time when stricter government regulations are in direct contradiction to reducing costs. Lubrication reliability is the solution; this article will describe how manufacturing plants can use “lubrication reliability best-practices” to reduce their energy consumption, emissions and operating costs—all at the same time.
The demand for stepping motors with high efficiency and low losses has been increasing right along with the existing focus on high torque. The selection of the most suitable grade and improvement in the fastening
of the laminated cores has reduced losses significantly at their peak when compared to conventional stepping
motors.
