If you have bought a cordless drill, impact driver, or circular saw in the last few years, you have probably seen “brushless” stamped across the packaging with a price tag to match. For tradesmen weighing up whether that premium is worth it, the short answer is that it usually is, but only once you understand what the technology actually does on site.<\/span><\/p>

This guide breaks down how a brushless motor works, why it improves runtime and tool life, and what that means for the way you buy, run, and maintain your kit. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Every electric motor turns electrical energy into rotational movement using magnetism. The difference between the two main types comes down to how they switch the current that keeps the motor spinning.<\/span><\/p>

A traditional brushed motor uses small carbon blocks, the brushes, that press against a rotating part called the commutator. As the motor turns, these brushes physically slide across the commutator to feed current into the windings and reverse it at the right moment. It works, and it has done for over a century, but that constant physical contact creates friction, heat, and wear.<\/span><\/p>

A brushless motor removes those carbon brushes entirely. Instead of mechanical contact doing the switching, a small electronic controller senses the position of the rotor and feeds current to the coils in a precisely timed sequence. That single change drives almost every benefit that follows.<\/span><\/p>

In most power tools, the layout works like this:<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
