In this video I talk about field oriented control (FOC) of induction motors.
0:00: Intro
0:46: Video topics
0:55: How do induction motors work?
2:19: Open-loop Voltage over frequency control
3:50: Closed-loop Voltage over frequency control
5:15: Voltage over frequency VS Field oriented control
6:38: Field oriented control of induction motors
9:50: Maximum torque per ampere (MTPA)

There's a lot of material online explaining about FOC when talking about permanent magnet motors, but I barely found any intuitive explanations regarding FOC of induction motors.
This video aims to fill that hole.
