Steady-State Voltage and Current Waveforms

When the steady state is attained, you can stop the simulation and plot the voltage and current waveforms using the variables V_ab and I_a sent back to the MATLAB workspace by the scope.

This figure shows the motor current and voltage waveforms obtained when the load torque is 50 N.m:
