Rate of rotation measurement using back-EMFS associated with windings of a brushless DC motor [PDF]

open access: yes, 2000
A system and method are provided for measuring rate of rotation. A brushless DC motor is rotated and produces a back electromagnetic force (emf) on each winding thereof. Each winding's back-emf is integrated and multiplied by the back-emf associated with

A Study of the Degradation of Electronic Speed Controllers for Brushless DC Motors [PDF]

open access: yes
Brushless DC motors are frequently used in electric aircraft and other direct drive applications. As these motors are notactually direct current machines but synchronous alternating current machines; they are electronically commutated by a power inverter.

The Control of Brushless DC Motors

open access: yes, 2015
In this paper, about brushless DC motors and their structures, working principles, types, control logic and control methods commonly used are given general information. Nowadays, using BLDC motors are increased because of their advantages. For example, simple structure, easy control, small size and high effiency etc.
