How Brushless DC Motors Work and Their Benefits

Brushless DC (BLDC) motors are becoming increasingly popular in various industries due to

their high efficiency, reliability, and durability. Let's discuss how BLDC motors work and

discuss some of their benefits. We will also explore some of the applications for which they are best suited. Let's dive in.


What are brushless DC motors?

BLDC motors are electric motors that use direct current (DC) instead of alternating current (AC). Unlike traditional brushed DC motors, BLDC motors do not require physical contact between the motor’s internals and its power source on the housing. Instead of brushes, they use electronic components to control the magnetic fields within the motor.


How do Brushless DC Motors Work?


BLDC motors are powered by direct current and a permanent magnet mounted to their rotor

shaft. The motor's speed and position are controlled by an electronic controller, which

manipulates the electric current running through the motor's stator windings. This is the setup for an outrunner motor, and can be reversed in inrunner motors for a more compact design.


This way, the magnetic field needed for forward or backward motion is created. The electronic control allows a BLDC motor to be operated at higher speeds and greater efficiency than a traditional brushed DC motor.


Benefits of Using Brushless DC Motors

BLDC motors offer several advantages over traditional brushed DC motors. Let's discuss some of them.


Improved efficiency - BLDC motors are much more efficient than their brushed counterparts,

allowing for longer run times and lower power consumption.


High speed - A BLDC gear motor can reach speeds far beyond those achievable with a

traditional brushed DC motor. This makes them ideal for applications that require fast

acceleration and quick responsiveness.


Low maintenance - With no physical contact between the power source and the motor, BLDC motors require little to no maintenance compared to brushed DC motors.


Quiet operation - BLDC motors produce far less noise than brushed DC motors. This makes

them perfect for applications in quiet environments such as medical settings or educational

institutions.


Compact size - BLDC motors can be much smaller than brushed DC motors, making them ideal for applications where space is limited.


Applications of Brushless DC Motors


BLDC motors are used in numerous applications, from consumer electronics to industrial

machinery. Some of the most common applications include HVAC systems, robotics, medical

equipment, and consumer electronics.
