■ Searching for material
By combining multiple categories, searching or reﬁning a search can be performed.
- Document categories … Function tutorials, application catalogs, white papers- Analysis types ………… Magnetic ﬁeld analysis, electric ﬁeld analysis, cogging analysis, etc.
- Module lists and others

Example:Searching by "loss"

Window

Reﬁning a search with "IPM Motor"

And further reﬁning with "Circuit / Control"

Motor Design Tool : JMAG-Express Online

Capable of Computing Basic Motor Characteristics
in Just 1 SecJMAG-Express Online is a parameter-based motor design support tool.
JMAG-Express Online now has the ability to evaluate all the motorcharacteristics like Torque- Speed characteristics, Loss characteristics,
Inductance characteristics, etc.
You can design motors anytime, anywhere,on the go or at home.
■ Evaluate torque, eﬃciency, loss, and inductance characteristics with graphs

and numerical values
Rotation speed vs torque characteristics, iron loss / copper loss characteristics, etc. are displayedin graphs in an instant. Motor characteristics can be conﬁrmed from tables of machine constants.
