JMAG-Express Online – Capable of Computing Basic Motor Characteristics in Just 1 Sec

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.

No installation required.
JMAG-Express Online can be used for free after creating an account.

Geometry sizing

A rough physical size can be decided simply by entering the minimum output expected of the motor.
Geometry and drive conditions can also be narrowed down by entering more information.

Efficiency Maps

Multiple maps can be compared when using the parametric function.

Temperature Evaluating

Generates a thermal equivalent circuit model of the motor and calculates the temperature of each part.

Design a Motor in 5 Minutes

When the desired power 50(kW) is specified, the size and comparative loading needed to achieve it are calculated automatically.
