Electric motors can be broadly divided into DC motors and AC motors, and AC motors can be further divided into synchronous
motors and induction motors. Currently, power electronics technology is used to control most of these motors. In this lecture,
"Electric Power Applications," students can learn the basics of variable speed motor control using power electronics technology
as an application of the "Electrical Machinery" and "Power Electronics" courses offered in the third year.
- Be able to explain and calculate coordinate transformations used in AC motors (synchronous motors, induction motors)
- Be able to explain and calculate the voltage equation and torque equation for induction motors using dp coordinates
- Be able to explain and calculate the voltage equation and torque equation of a synchronous motor in dp coordinates
- Be able to explain and calculate the control methods for each motor
