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

JMAG-Express Online is a parameter-based motor design support tool.
JMAG-Express Online now has the ability to evaluate all the motor characteristics like Torque- Speed characteristics, Loss characteristics, Inductance characteristics, etc.
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 NEW!

The motor operating range, as well as efficiency and power output at each operating point, can be checked by using the map function. When creating maps, voltage and current limits can be applied. Multiple maps can be compared while using the parametric function.

Temperature Evaluation NEW!

The thermal model is evaluated using various heat generation sources like Copper Losses, Iron Losses, and Mechanical losses.

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.
