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. Nowerdays, power electronics technology is used for most of these motor controls. In this lecture
"Electric Power Application", you can learn the basics of motor variable speed control using power electronics technology
as an application of "Electrical Equipment Basics" and "Power Electronics" that will be held in the third year. The difficulty
level of acquisition is set to a level that undergraduate students can understand.
The goals of this course are to
- be able to understand and explain mathematical models of DC motors, synchronous motors, and induction motors.
- be able to draw and explain the block diagram of the mathematical model of each motor.
- be able to explain by drawing a control block diagram including the control unit.
- be able to show and explain the system configuration of each control method.
- be able to understand and explain mathematical models of DC motors, synchronous motors, and induction motors.
- be able to draw and explain the block diagram of the mathematical model of each motor.
- be able to explain by drawing a control block diagram including the control unit.
- be able to show and explain the system configuration of each control method.
- Being able to explain and calculate coordinate transformations used in AC motors (synchronous motors, induction motors).
- Be able to explain and calculate voltage equations and torque equations based on the dp coordinates of induction motors.
- Be able to explain and calculate voltage equations and torque equations based on the dp coordinates of synchronous motors.
- Be able to explain and calculate the control method of each motor.
