Are Brushed Motors Ac Or Dc: Unveiling The Power Source

Brushed motors, including both brushed DC and AC/DC universal motors, are often criticized for several reasons. However, one of the primary concerns, albeit somewhat overstated, relates to the gradual wear and tear of the graphite brushes and the segmented copper commutator they ride on over time. These components wear out as the motor operates, which can lead to a fine, and in some cases, hazardous situation. Brushed motors, whether they run on AC or DC power, are subject to this issue, which has prompted discussions about their durability and safety. This topic has been debated, with some expressing exaggerated concerns, as of August 7, 2022.

Is a brushed motor considered a type of DC motor? In the realm of DC motors, two primary categories exist: brushed motors and brushless motors, often referred to as BLDC motors. The key distinction lies in the presence or absence of brushes. DC brushed motors feature brushes as a vital component, serving the crucial function of commutating the motor to induce rotation. Conversely, brushless motors eschew this mechanical commutation mechanism, relying instead on electronic control for motor operation. In summary, brushed motors are indeed a subset of DC motors, relying on brushes for commutation, whereas brushless motors employ electronic control for this purpose.
