Induction and Synchronous Motor Fundamentals
Rebecca Johnson, P.E.
Overview
The
two most common motor classes are synchronous and induction motors.
Synchronous motors are more efficient than induction motors, but are more
expensive and complicated and typically have a shorter life span. This
course covers fundamentals of these motor classes and is geared towards
engineers of all disciplines who are responsible for sizing, specifying,
selecting, or purchasing electric motors.
The student must take a multiple-choice quiz consisting of
ten questions at the end of
this course to obtain PDH credits.
