AC/DC Motors and Drives (47908)
- System Components – Study the basic terminology and principles involved with motors and drives to develop a foundation for the other principles presented in this course
- AC/DC Motors – Understand the torque-related principles of AC motors and the magnetism-related principles of DC motors and how the laws of magnetism, speed, horsepower, and torque produce power
- Selecting a Replacement Motor – Interpret a motor’s nameplate and understand the nameplate data so you can find a replacement motor or an acceptable substitute
- Line Protection and Filtering – Examine the reasons behind understanding fuses and filtering devices:
- Protect personnel from electrical dangers
- Operate an electrical code compliant system
- Extend the life of equipment through proper fusing and filtering
- Electrostatic Concepts – Avoid electrostatic discharges by understanding what causes them and what components are affected by them
- AC/DC Drives Hardware – Consider the differences between AC and DC drives, and learn more about the functions, components, and firmware of AC drives
- AC and DC Braking – Stop a motor using three different methods, learn the advantages and disadvantages of each, and explore the two main electrical braking methods and how they relate to AC or DC drives
- Testing the System – Study the five different electrical measuring tools that can be used to help diagnose problems in AC/DC drives
- Checking the System – Master the pre-power and power-on checks that will locate bad alignment and bad wiring in a drive
- Using the HIM with the Drive – Monitor the parameters of a drive that will help you program, maintain, and troubleshoot an AC/DC drive using a Human Interface Module, commonly call the H-I-M or HIM
- Selecting a Drive – Analyze the applications of variable speed and motion control, matching the proper drive with the proper application
