MEC 205 - Troubleshooting Advanced Motor Controls

Credits: 3
3 Skills Lab Hours

Prerequisites: EET 103  

 
Description
This course covers the principles, application, troubleshooting and maintenance of rotating electrical motors as used in industry. Topics include various types of single and three-phase alternating current (AC) motors, various types of direct current (DC) motors, reduced voltage starting and braking. The course builds upon principles and applications covered in foundational electrical courses. All course material is supplemented with practical hands-on exposure to the items described.

Learning Outcomes
Upon successful completion of the course, the student will:

  1. Apply basic safety rules to work with electrical rotating machinery under 600 volts.
  2. Describe the operation, function, wiring and schematic symbols for DC series, DC shunt and DC compound motors.
  3. Measure electrical and mechanical motor speeds, torques and loads.
  4. Analyze torque, speed, power and efficiency for DC motors.
  5. Measure AC waveforms, frequency, apparent power, power factor, effective voltage, peak voltage, single-phase and three-phase power.
  6. Describe the operation and function of motor braking by plugging, electromechanical braking, DC injection braking and dynamic braking.
  7. Describe the operation and function of resistor, autotransformer and part-winding motor starting.
  8. Troubleshoot various starting and braking methods.
  9. Describe the function and operation of silicon controlled rectifiers (SCR) and how they may be applied for motor speed control.
  10. Measure the performance characteristics of AC and DC electrical motors.
