Along with the advancement of motor technology that enables high-performance
and miniaturization of a motor, electromagnetic field simulation based
on the Finite Element Method (FEM) has become indispensable as a motor
Similarly, control simulation tools, including MATLAB/Simulink, PSpice,
and PSIM, are used proactively to develop motor control circuits, as PWM
and other vector controls are now commonly used for circuits.
Precise and detailed simulation of motor behavior is essential to develop
innovative motors. These simulations would not be available without linking
an electromagnetic field simulation with a circuit/control simulation.
JMAG-RT is the group of JMAG features making the configuration of the motor
drive simulation system possible. Using an FEM model, JMAG-RT generates
a behavior model that can be applied to a control simulation.
Torque characteristics from the electromagnetic field simulation and losses
of each circuit component from the control simulation can be derived simultaneously.
A motor and a drive system can be designed concurrently by sharing a single
motor model among motor designers, circuit designers, and control designers.
