Understanding Brushed and Brushless Motors
Core Differences
Brushed motors and brushless motors are two distinct types of electric motors commonly used in various applications, including electric skateboards. The core differences between these motor types lie in their commutation methods and overall performance.
Brushless motors utilize electronic commutation, which means they rely on electronic circuits to switch the current flow in the motor windings. On the other hand, brushed motors use physical brushes and a commutator to achieve commutation. This fundamental difference in commutation methods has several implications for their performance.
One significant advantage of brushless motors is their higher efficiency compared to brushed motors. The absence of brushes eliminates friction and reduces energy loss, resulting in improved overall efficiency. Brushless motors offer better control over speed and torque due to their electronic commutation system.
In terms of cost and simplicity, brushed motors have an edge over brushless motors. Their design is relatively simpler, with fewer components involved. As a result, brushed motors are generally less expensive than their brushless counterparts. This affordability factor makes them a viable option for beginners or individuals on a tighter budget.
Operational Mechanics
To understand how these motor types function, let’s delve into their operational mechanics.
Brushless motors generate rotational force using a combination of magnets and electromagnets. They consist of a stationary outer magnet (stator) and a rotating inner electromagnet (rotor). By controlling the electric current flowing through the electromagnets using an electronic circuit, the motor produces rotational motion.
In contrast, brushed motors employ brushes that make direct contact with the rotating armature (coil) connected to the power source. As the armature rotates within the magnetic field created by stationary magnets, electrical current flows through different segments of the armature via the brushes and commutator. This flow of current generates torque and drives the motor’s rotation.
Impact on Electric Skateboards
