Back to Basics: Electric Motors (Source: Consulting-Specifying Engineer)

By Jeff Thomas

Electrical engineers should understand the basics of motors and how to specify them in various applications. This session will cover background information on motors, the different types, how NEMA classifies motors and what that means to electrical engineers.

Learning objectives:

Understand the typical types of motors: induction, synchronous, stepping, specialty.
Learn the NEMA motor types and their main differences (A, B, C and D).
Know how best to start/control motors, including across the line, soft and variable frequency drive.
Review the things to consider and trade-offs when selecting a motor.
