Difference between a Brushed and Brushless DC Motor

Direct Current (DC) motors are used in many industries known for their reliability and versatility. The two main types mainly brushed and brushless DC motors have unique features that make them suitable for different applications. In this blog we will discuss what exactly a DC motor is and will understand the difference between the two. So let us get started!
Understanding a DC Motor.

In simple words a dc motor is a direct current motor that converts electrical energy into mechanical energy. Generally a DC motor uses magnetic fields and currents to convert electrical energy into mechanical energy. The motor generally has two parts, one is the stator and the other is the rotor. The Stator maintains a magnetic field, whereas on the other hand, the rotor is also termed as the armature rotates inside the magnetic field.

Difference between Brushed DC Motors and Brushless DC Motors

a. Basic Design
Brushed DC Motors use carbon brushes and a commutator to transfer electric current.
On the other hand, a Brushless DC motor mainly focuses on electronic controllers to direct the current thereby eliminating the need for brushes.

b. Durability
Brushes and Commutators wear down over time that leads to shorter lifespans and frequent replacements.
With no brushes or any commutators in between, brushless DC motors have a minimal wear and tear over time that leads to a longer lifespan.

c. Efficiency
Brushed DC motors are less efficient due to energy loss that is caused by friction between the brushes and commutators resulting in heat generation.
On the other hand, Brushless DC motors are highly efficient as there is no friction from the brushes, thereby reducing energy loss and heat generation.

d. Cost
Brushed DC motors are cost-effective.
On the other hand, brushless DC motors are most expensive because of the advanced electronic components and manufacturing processes involved.

e. Complexity
Brushed DC motors are simple to use and repair.
On the other hand, a brushless DC motor is considered to be more complex that requires specialised knowledge for operation, troubleshooting and repairs.

f. Key Advantage
As a DC Motor is low cost and easy to repair, it is ideal for budget conscious users or meant for applications that require less power, effort and operational intensity.
On the other hand, a Brushless DC Motor is highly efficient and durable and is perfect for advanced applications.
