Brushless Vs Brushed Motor: Why You Should Know The Difference

Everyone knows that a cordless drill is a drill that does not need to be plugged in. Suitable for people who work in areas that are far from power outlets, work outside the home, or work where the power cord of an electric drill cannot reach and can be easily carried. The cordless drill uses battery power to drive the motor to rotate. In this article, we will focus on the motor of a cordless drill. There are generally two types: brushed motors and brushless motors. What is the difference between these two types of motors? Let's get to know the cordless drill motor together!

Types of Cordless Drill Motors

1. Brushed motor: It works by passing electric current through two brushes attached to the commutator and sending the electric current to cause the motor to rotate. Thus causing the work of the drill.
   
2. Brushless Motor: It uses the frequency of electricity that comes from the electronic circuit in the drill itself to drive the motor to make the motor shaft rotate. This means that there is no need for carbon brushes anymore. So this is the origin of the name of this type of motor. This circuit board, although small, is very powerful and very complex.
   

Pros-Cons of Brushed Motors

• Pros : This type of motor has easy maintenance. Even though their work requires friction with other components, when these carbon brushes begin to wear out they can be easily repaired or replaced by yourself. Most importantly, they are cheaper than brushless motors. Because it is a motor that does not have a complicated circuit board or sensors to control current like a brushless motor.
• Cons : It is probably a matter of performance that is inferior to brushless. Because it cannot control the electricity supply and will work at full power as soon as it is pressed down. This means that heavy work and light work will lose energy equally. Resulting in having to charge the battery more often.

Pros-Cons of Brushless Motors

• Pros : This type of motor has a longer lifespan. The advantage is that there is less wear and tear because there are no brushes to rub against the commutator. No need to worry about sparks as there are no brushes. There is no heat buildup in the drill body. Thus helping to save more battery life. Importantly, it also provides higher torque than a brushed motor and provides more stability in running.
• Cons : The main thing is that they are quite more expensive than motors with carbon brushes because brushless motors have more complicated technology and are more difficult to repair, making the cost more expensive as well. Therefore, it is suitable for technician work from general use to professional technicians who want to buy and use for a long time to make it worth the money spent.
