SPWM driven 3 phase induction motor run in reverse.

4 views (last 30 days)
The simulation works but the problem is rotor speed of the asynchronous machine is in negative direction, i dont know the reason and is there any suggestions to make it run in positive direction? The 3 phase inverter is driven by SPWM signal. Attached is my model. Thanks.

Flip vb with vc sine waves and change the sign of load mechanical torque to negative torque.
