Motor Fundamentals

  • 8:00am-4:30pm

This course begins with a brief review of electrical fundamentals including AC and DC electricity then expands to cover magnetism, electromagnetism, induced voltage, inductive and capacitive reactance and capacitors.  It then covers motor principles, induction motors, common single-phase and 3-phase motors, 3-phase soft start methods, VFD operation and nameplate data.  Then motor electric troubleshooting instrument are described and common electrical and mechanic motor problems are covered.  Next motor protection devices, common motor circuits and DC motors, brushless DC motors and stepper motors are covered.  Class overview:

  • Describe the basic operation of electrial AC and DC circuits including the relationship between volts, amps and ohms.
  • Describe how magnets and electromagnets are used to operate a motor and the usefulness of inductive and capacitive reactance as it relates to motors.
  • -Describe the components that make up a motor and the operation of the various types of single-phase and 3-phase motors and the common methods for soft-starting 3-phase motors.
  • Demonstrate how to interpret the information found on old and new motor nameplates.
  • Identify the various electrical instruments used to troubleshoot and test motor operation and describe the procedure for using them.
  • Describe how common motor protective devices work.
  • Describe the operation of common DC motors, brushless DC motors and stepper motors.
