Brushed vs Brushless Motors: Why the Extra Cost?

As we know, there are two types of Marathon Micro Motor: Brushed vs Brushless Motors. What’s the difference? Let’s have a look.

In a conventional electric motor, a rotor (a rotating portion of the machine) is driven in a stator (fixed portion). Both are connected by an electrical connection: a current collector or a commutator that is in contact with a small carbon brush.

Using brushless technology, the rotor consists of a magnet and a coil stator that alternately positively or negatively. Therefore, the magnetic pole attracts and repels, allowing the motor to rotate. The advantage is that there is no physical contact between the rotor and the stator. Energy is transferred from one to the other by the magnetic force between the electromagnets.

Powered by direct current, the motor operates with alternating current generated by an electronic card that converts the direct current into a three-phase variable frequency. Thus, the coils are alternately fed to create a rotating field and thus produce a rotation. An electronic module built into the motor or housing continuously regulates the current so that the motor runs at peak efficiency. This improves overall performance and provides real value for money.

In short, brushless motors are better than brushed units. Users can take advantage of reduced maintenance, increased efficiency, and reduced heat and noise. A brushless motor is a synchronizing unit having one or more permanent magnets. Power tools with brushless motors are now considered high-end products.
