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.
An engineer’s diary
JMAG is FEA-based and allows design to proceed while evaluating both the magnetic properties and thermal properties of the motor at the same time.
By having magnetic field analysis and thermal analysis models share the design variables, for example, changes to dimensions can be reflected in both the magnetic field model and the thermal model at the same time. In addition, the magnetic and thermal results can be evaluated on a single screen.
Check the efficiency maps to see the temperature during maximum power. If the part temperature is too high, then evaluations can be run very easily simply by repeating a process of changing the design variable values and checking the efficiency maps and temperature again.
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.
