As explored in the article “The Difference Between Brushed and Brushless Motors,” the world of motors is divided into two fundamental categories: brushed and brushless. While it’s true that one uses brushes and the other does not, the real question lies in understanding the purposes and distinctions between these two technologies.
Before we delve into their comparative analysis, let’s take a moment to explore each type in isolation.
What is a brushed motor? Brushed DC motors operate by utilizing wound wire coils, known as the armature, acting as a two-pole electromagnet. The key to their operation is the commutator, a mechanical rotary switch that reverses the direction of current twice per cycle. This reversal causes the electromagnet’s poles to attract and repel against the permanent magnets located on the motor’s exterior. Simultaneously, the commutator switches the polarity of the armature’s electromagnet as its poles interact with those of the permanent magnets, ultimately generating a direct current.
These brushed motors have been a workhorse in various applications for decades, but they come with inherent limitations.
The article goes on to provide a comprehensive comparison of brushed and brushless motors, shedding light on their respective advantages and limitations. This knowledge is invaluable for industries ranging from manufacturing to robotics and beyond.
