Introduction to AC Electrical Motors
Credits: 3 PDH
PDH Course Description:
This course provides an introductory overview of AC series, synchronous, and induction motors.Topics:
- List three basic types of ac motors and describe the characteristics of each type.
- Describe the characteristics of a series motor that enable it to be used as a universal motor.
- Explain the relationships of the individual phases of multiphase voltages as they produce rotating
- magnetic fields in ac motors.
- Describe the placement of stator windings in two-phase, ac motors using rotating fields.
- List the similarities and differences between the stator windings of two-phase and three-phase ac
- motors.
- State the primary application of synchronous motors, and explain the characteristics that make
- them suitable for that application.
- Describe the features that make the ac induction motor the most widely used of electric motors.
- Describe the difference between the rotating field of multiphase motors and the "apparent"
- rotating field of single-phase motors.
- Explain the operation of split-phase windings in single-phase ac induction motors.
- Describe the effects of shaded poles in single-phase, ac induction motors.
