Description

This course reviews basic electric machines, such as three-phase induction machines and three-phase synchronous machines. After a brief review of three-phase induction motor, the course begins with the operation and analysis of the single-phase induction motor. Double-revolving field theory and the equivalent circuit derived from that are used to analyze the operation of the single-phase induction motor. The single-phase series motor is also discussed and analyzed. Speed control of the single-phase induction motor is discussed. Various speed control methods for three-phase induction motor, such as voltage control, variable voltage variable frequency control, slip frequency control, rotor resistor control, etc., are introduced. The block diagram implementation of these control methods is introduced. The characteristics of these control methods are compared. Their application is also discussed. The course will also discuss the characteristics and application of special motors, such as servo motor, stepper motor, brushless DC motor, and PM motor. The characteristics of the three-phase synchronous motor will also be discussed. At the end, the dynamic characteristics of DC machines are introduced.


The course builds on material from ELEC 333, and relies on additional background acquired in either ELEC 431 or ELEC 353.
