What Is the Difference Between Brushed and Brushless Motors? Insights from Huameng

Electric motors are the driving force behind a plethora of modern devices, ranging from scooters and e-bikes to robots and industrial machinery. Some of the most commonly used ones are brushed and brushless motors. Even though they do the same, their internal workings, output, and areas of operation are different in a lot of ways.

At Huameng, we are the experts in 150 cc scooter motors, gear motors, and advanced 48v brushless motors among other high-efficiency motors for a variety of uses. Here, we are going to break down the main differences between brushed and brushless motors and help you to decide the one best for your application.

Brushed Motors: Simple and Time-Tested

Brushed motors use carbon brushes and a commutator to supply current to the motor windings. As the rotor spins, the brushes maintain contact with the commutator, allowing electricity to flow and generate motion.

Pros:

• Simple design and low production cost
• Easier to control with basic circuitry
• Ideal for light-duty applications such as toys, small tools, or low-speed scooters

Cons:

• Brush wear over time leads to maintenance and shorter lifespan
• Sparking and friction can cause energy loss and overheating
• Typically less efficient than brushless alternatives

Brushed motors can still be found in some entry-level 150 cc scooter motor systems, where cost-saving and simplicity are prioritized.

Brushless Motors: Efficient and Maintenance-Free

In a bürstenloser Motor, the mechanical brushes and commutator are replaced by electronic controllers. The motor uses a permanent magnet rotor and electronically commutated stator coils to produce rotation—eliminating the physical wear points found in brushed designs.

Pros:

• Longer lifespan due to lack of physical contact
• Higher efficiency and lower energy loss
• Reduced noise and smoother operation
• Ideal for high-performance applications, such as e-bikes, drones, and automation systems

For example, Huameng’s 48v brushless motor is widely used in electric vehicles, where performance, quiet operation, and durability are critical.

Cons:

• Higher initial cost
• Requires electronic controller for operation
• Slightly more complex integration into systems

Application Differences

The choice between brushed and brushless depends largely on your use case:

• Brushed Motors: Best for simple, low-cost systems where occasional maintenance is acceptable.
• Brushless Motors: Preferred for demanding, continuous-use applications where efficiency and reliability are key.

In the case of a gear motor, brushless versions offer quieter, more precise movement, making them ideal for robotics, automation, and medical equipment. Brushed gear motors, on the other hand, remain popular in budget-sensitive environments.
