Motor Design

Last modified at 7 Jul 2022

The advantages of JMAG to electric machine analysis have been proven time and again. Even though electric machines are considered mature products, they still face new demands for higher performance. These demands have increased competition among machine designers to extract the most performance from a design. After more than 100 years, most of the easy innovations have already been made and deriving further performance gains requires finite element analysis (FEA) to identify previously overlooked or underestimated aspects of machine design. Since JMAG’s release, it has been utilized in a number of motor development projects around the world. Our accumulated knowledge and experience in motor design enables us to provide powerful yet easy to use simulation technologies.

[No. 51] Current-density J

Next in alphabetic sequence is J — which could stand for 'JMAG' or 'JAPAN', but instead let us think of J as the common symbol for current-density. Sometimes when I think about current-density I’m reminded of the notice that is printed on cigarette…

[No. 50] Insulation

In this series of Engineer’s Diary, the topics are selected by following the letters of the alphabet, giving an almost random walk through the field of electrical engineering. ‘I’ is next…; so let’s think about insulation.

[No. 49] Hair-pin winding

The hair-pin winding has become prominent in drive-train motors for electric and hybrid vehicles, with many creative examples in manufacturing. Although ‘push-through’ hair-pin coils have long been used in other industries, especially in heavy machi…

Motor Design Tool　JMAG-Express Online

JMAG-Express Online is a parameter-based motor design support tool.
It is possible to obtain in an instant the startup voltage constant, torque constant, inductance characteristics, current vs torque characteristics, rotation speed vs torque characteristics, iron loss / copper loss characteristics, etc. merely by inputting a geometry template, materials, windings, and drive conditions.
Because JMAG-Express Online can be used with tablets and smartphones, you can design motors anytime, anywhere, on the go or at home.
