Understanding Brushless Motors: A Comprehensive Guide

Click For Summary
SUMMARY

This discussion centers on the complexities of understanding brushless motors, specifically 3-phase brushless motors commonly used in applications like floppy disk drives. Participants express confusion regarding whether these motors are controlled by AC or DC power. A recommendation for further reading includes the "TI Motor Control Compendium" which provides a comprehensive overview of brushless motor operation and concepts such as reluctance torque. Additionally, there is a mention of building an electronic speed controller for 3-phase brushless motors.

PREREQUISITES
  • Understanding of 3-phase brushless motor technology
  • Familiarity with AC and DC motor control principles
  • Basic knowledge of electronic speed controllers
  • Awareness of torque concepts, including reluctance torque
NEXT STEPS
  • Research "3-phase brushless motor control techniques"
  • Study "Electronic Speed Controller (ESC) design for brushless motors"
  • Explore "Reluctance torque in brushless motor operation"
  • Read the "TI Motor Control Compendium" for in-depth knowledge
USEFUL FOR

Engineers, hobbyists, and students interested in motor control systems, particularly those focusing on brushless motor technology and electronic speed controllers.

So here is the thing.

I was searching the internet for information about brushless motors. Everywhere I went, they had mixed statements about it. Long threads about which is it, is it controlled by AC or DC or what have you.

I am interested in book, that is covering this subject in depth. I am focusing mainly on 3-phase brushless motors, like the ones found in old floppies. And if I'm confused if it is or isn't 3-phase, I want to learn what it actually is.

Please suggest me a book on this subject.

Thank you.

Thank you. I did like it. But it introduced a few concepts that scared me a bit. Reluctance torque etc. But, the operation of brushless motor is explained very well. I will try and build this electronic speed controller for 3 phase brushless motors.
 
scared me too. I will no longer be able to fix wife's washing machine when it's built around computer controlled multiphase motors.

hahaha yes, well it certainly won't make my life easier either :D
