MEC 204 - AC/DC Electronic Drives

Credits: 3
2 Lecture Hours 2 Lab Hours

Description
This course covers the principles, configuration, troubleshooting and maintenance of electronic motor drives that are used in industry.  Topics include various types of direct current (DC) electronic drives, alternating current (AC), variable frequency and vector drives.  The course builds upon principles and applications covered in foundational electrical courses.  All course material is supplemented with practical hands-on experiences performed by the student in the laboratory.
Learning Outcomes
Upon successful completion of the course, the student will:

  1. Describe the function, operation and construction of DC spindle drives, axis drives and pulse width modulation drives.
  2. Describe the role of current, voltage and velocity feedback from a tachometer in DC drives.
  3. Operate DC motors using armature and field control.
  4. Configure variable frequency AC drives to control starting, stopping, speed, torque, boost and braking.
  5. Troubleshoot drive faults, parameters and systems incorporating variable frequency AC drives.
  6. Describe vector control, current and encoder feedback in an AC vector drive.
  7. Write motion control programs to drive servo and stepper motors.
  8. Identify the operation and main components of a servomotor.
  9. Select test equipment and troubleshoot the various types of electronic drives.
