Simulation of induction motor startup

MotorAnalysis is capable of transient FEM-based simulation taking into account rotor motion, eddy currents, saturation of iron cores and etc. Here is an example of the 2D FEM-based simulation of the induction motor startup at rated load.

The simulation results as stator line currents, torque, load and rotor speed vs. time:
