Why is a brushless motor better？

Brushless Motors - An Overview

Brushless motors are gaining more popularity due to their superior performance, efficiency, and reliability compared to their brushed counterparts. In this article, we will explore why micro brushless motors are better than brushed motors.

Working Principle

The working principle of a brushless motor involves a permanent magnet rotor and an electromagnet stator. The rotor rotates due to the interaction of the magnetic fields created by the rotor and stator. The flow of current changes as the rotor rotates, creating a rotating magnetic field that keeps the rotor turning.  In contrast, brushed motors utilize the interaction of a rotor and a commutator. By coming into physical contact with a commutator, the motor creates the magnetic field needed to turn the rotor.  

Advantages of Brushless Motor

Higher Efficiency

Brushless motors are more efficient than brushed motors.  Brushless motors have fewer internal friction points than brushed motors. Because they do not have brushes that rub against the commutator. This reduces heat buildup and energy losses in the motor, making them more efficient.

Maintenance-Free Operation

One of the primary advantages of micro brushless motors is that they require no maintenance.  Since they are brushless, there are no brushes that can wear down. This means that the motor can run for an extended period without any maintenance, reducing downtime, and increasing overall productivity.

Compact Design

Being electrically commutated, 8mm BLDC Brushless Vibration Motor has a more streamlined design compared to their brushed counterparts. This means that they can be designed to be much smaller in size, making them suitable for use in compact devices such as drones, medical equipment, and wearable technologies.

Longer Lifespan

Brushless motors have a longer lifespan than brushed motors due to their brushless design and superior control systems, which reduces wear and tear on the motor components.
