Issue 3 How to Perform Detailed Motor Design [March, 2014]

This series features descriptions of our thoughts about motor design, targets beginning motor designers and provides information about design themes for those seeking to acquire basic knowledge about the subject. In the previous issue we discussed initial designs, arranging concept design plans as a starting point for detailed designs. In this edition, the third and last entry in the series, we will look at detailed designing for final designs.
Trade-offs are a key factor when it comes to detailed designs and they also happen to be areas in which JMAG-Designer and JMAG-Express excel. By describing case studies developed through trial and error while using JMAG-Designer or JMAG-Express we plan to provide hints that will help you move ahead with detailed design of motors.

Issue 2 Moving Forward with Motor Concept Design [January, 2014]

In the September 2013 issue of this newsletter, the first of these ongoing columns, I gave an explanation about the background to starting a course on motor design. In this issue and the second column, I'll finally get around to explaining what's involved in designing motors. The theme of this column will be to provide a starting point for concept design. Although it may seem a little boastful, what I'll do is go over some of the results that we have obtained through our studies and, hopefully, these will be of use to your work.

Issue 1 Why have a JMAG Motor Design Course. [September, 2013]

Many JMAG Newsletter readers have expressed an interest in motor design, so we decided to do a series on the subject from this issue. But, having said that, we're analyzers and not motor design specialists. That makes it a bit rich to say we're holding a course. Nonetheless, we kick off this series with the thought that it might be useful for readers to pass on what we've learned about motor design through plenty of painful experiences in the past.

Motor Development

Starting With Vibration Noise Analyses Vol. 1 (Motor Edition 1) [January, 2014]

Vibration noise has become an unavoidable issue when dealing with electrical equipment in recent years and it seems magnetic circuit designers are somewhat distant from vibration sound analyses. In this series, I would like to give a description of initiatives toward a vibration noise analysis where electromagnetic force obtained from JMAG acts as the vibratory source. I'd like to focus on motors for the first entry in this column and describe modeling methods to get a grasp on an analysis of resonance from electromagnetic force and eigenfrequency. It would be wonderful if motor designers not involved in electromagnetic vibration took it on or joined with machinery designers to devise methods to counteract vibration noise.
