Bldc motor: A brushless DC Motor ( BLDC

A brushless DC Motor ( BLDC Motor ) is a highly efficient and powerful motor powered by a direct current (DC) supply. It does not have brushes and commutator. It commutated electronically to generate the magnetic field. Due to its power and efficinecy, these brushless DC motor used in various applications such as industrial automation, medical devices, electric vehicles and others. ABSTRACT This application note provides a general overview of BLDC motors , including their advantages against other commonly-used motors , structure, electromagnetic principles, and mode of operation. This document also examines control principles using Hall sensors for both single-phase and three-phase BLDC motors , and a brief introduction to sensorless control methods using BEMF for a three-phase BLDC motor . INTRODUCTION Brushless Direct Current ( BLDC ) motors are one of the motor types rapidly gaining popularity. BLDC motors are used in industries such as Appliances, Automotive, Aerospace, Consumer, Medical, Industrial Automation Equipment and Instrumentation. A brushless DC motor (also known as a BLDC motor or BL motor) is an electronically commuted DC motor which does not have brushes. The controller provides pulses of current to the motor windings which control the speed and torque of the synchronous motor.
