Your model has the following issues:
You are using the Space Vector PWM (3-Level) block instead of the regularSpace Vector PWM appropriate for a 2-Level converter
The units on the SVPWM input block are misaligned. The Vdc input is 200V but the Vab input is only +/-1 leading to very low duty ratios.
The sinewave frequency is somewhat high at 600 Hz so you will see oscillations in speed once you resolve the above two issues.
