A synchronous machine with permanent magnets starts braking from nominal speed by feeding a diode bridge,
which in turn feeds a braking resistor.
Since induced voltage is reduced proportional to falling speed, the braking resistance is set proportional
to speed to achieve constant current and torque.
-Default machine parameters are used
+Default machine parameters are used. The RonDiode and GoffDiode parameters of the diode bridge are both increased to 1e-4 to avoid numerical issues when the variable resistor voltage gets close to zero.
