What are Brushed Motors?
Brushed motors have been in use for over a century and are widely used in small to medium-sized applications, including household appliances and power tools. Brushed motors operate by passing a current through carbon brushes that make contact with a rotating armature, generating electromagnetic force that spins the rotor. The brushes also serve as a commutator, reversing the current’s direction as the armature rotates, resulting in a continuous rotation.
One of the significant advantages of brushed motors is their simplicity and lower cost. However, they are also less efficient, generate more heat, have a shorter lifespan, and require more maintenance than brushless motors.
What are Brushless Motors?
Brushless motors are a newer technology and operate using a more complex design than brushed motors. Instead of brushes, brushless motors use a control unit that manages the current and magnetism in the rotor. The rotor has multiple permanent magnets that interact with electromagnets on the stator, creating a rotating magnetic field that spins the rotor.
Brushless motors have several advantages over brushed motors. They are more efficient, generate less heat, have a longer lifespan, and require less maintenance. They are also more reliable, have smoother and quieter operations, and can operate at higher speeds and torques.
Differences between Brushed and Brushless Motors
The primary difference between brushed and brushless motors is the design and how they operate. Brushed motors have brushes that come into contact with the rotating armature, while brushless motors use a control unit and permanent magnets.
Brushed motors are simpler and less expensive but have lower efficiency, generate more heat, and have a shorter lifespan. Brushless motors are more complex and more expensive but have higher efficiency, generate less heat, and have a longer lifespan.
Another significant difference between brushed and brushless motors is their maintenance requirements. Brushed motors require more maintenance due to the brushes and commutator, while brushless motors require less maintenance due to their design.
Advantages of Brushed Motors
- Simpler design
- Lower cost
- Widespread availability
- Easy to control speed and torque
- Good for low power applications
Advantages of Brushless Motors
- Higher efficiency
- Longer lifespan
- Lower maintenance requirements
- Smoother and quieter operation
- More reliable
- Better performance at high speeds and torques
Choosing the Right Motor for Your Application
When choosing between a brushed and brushless DC motor, it is essential to consider the specific application’s requirements and constraints. Factors to consider include:
- Power requirements: Brushed motors are suitable for low-power applications, while brushless motors are better for high-power applications.
- Speed range: Brushless motors have a wider speed control range than brushed motors, making them more suitable for high-speed applications.
- Control complexity: Brushed motors are simpler to control than brushless motors, which require electronic speed controllers.
- Maintenance requirements: Brushless motors have lower maintenance requirements than brushed motors, which require regular brush and commutator replacement.

FAQs
What is the difference between a brushed and brushless motor?
Brushed motors have carbon brushes that make contact with a rotating armature, while brushless motors use a control unit and permanent magnets to generate a rotating magnetic field.
Which is more efficient, a brushed motor or a brushless motor?
A brushless motor is generally more efficient than a brushed motor because there's no physical contact between the rotor and stator, which reduces energy loss due to friction and heat.
Which is more expensive, a brushed motor or a brushless motor?
A brushless motor is generally more expensive than a brushed motor because it requires more complex control systems and manufacturing processes.
What are brushed motors used for?
Brushed motors are used in a wide range of applications, including power tools, toys, and small appliances.
What are brushless motors used for?
Brushless motors are used in a wide range of applications, including robotics, medical equipment, and aerospace.
Can Rax Motor provide customized electric motors?
Yes, Rax Motor can provide customized electric motors to meet specific customer requirements.
Which type of motor should I choose for my application?
The choice between a brushed motor and a brushless motor depends on the specific requirements of your application. For low-cost applications that don't require high efficiency or long lifespans, a brushed motor may be suitable. For high-end applications that require precise control and high efficiency, a brushless motor may be the better choice. Rax Motor can help you choose the right motor for your application based on your requirements.
