Project 2 - Modeling of 3 phase Induction Motor Drive

1)

simulink model

voltage is given as 800V ie given in parameters

in step block the step time is given as 0.1

blocks inside the V/HZ control subsystem

in the asynchronous machine parameters, the rotor type is changed into squirrel cage as advised in the parameters

output waveform

when constant torque at 20NM

*For back emf to speed relation, assume a linear rate from 0.25 to 1, with speed changing from 500 RPM to 2000 RPM
