In recent years, vibration reduction has become important in motor design. At the design study phase, there is a demand to estimate vibration with high accuracy using vibration analysis software which uses the torque obtained from magnetic field analysis and uses the electromagnetic force acting on each tooth. In JMAG, it is possible to output the torque of a rotating machine model and the excitation force on each teeth using a pre-installed script.
This document presents sample data and procedures to learn how to use an “electromagnetic force output for NVH” script.
