Motor Control For Designers (Part 1): Basic Principles Of Motor Theory
by Dennis Feucht, Innovatia Laboratories, Cayo, Belize, How2Power Today, Jul 15 2025
Focus:
With the rise of electronically commutated motors such as brushess dc motors, permanent
magnet synchronous motors and variable reluctance motors, requirements for motor control
and motor drive design are growing. This article kicks off a mini-course on motors and
circuits that aims to inform both circuit and motor designers by covering 1) motor theory,
2) motor design, 3) motor-drive design, and 4) motion control. The goal is to convey a
working design knowledge of electric machines and the electronics and software to control
them. Topics in part 1 include motor theory history, quantities of electricity and
magnetism, magnetic reference frames, Maxwell's equations, magnetic-electric analogs, and
inductance.
What you’ll learn:
- How to understand the key terms, concepts and relationships in electricity and magnetism that are needed to explain how motors work
