Brushed DC Motors: Features and Applications
How Brushed Motors Are Built
Brushed DC motors are simple machines that turn electricity into motion. They have important parts like a rotor, stator, commutator, brushes, and magnets. The rotor spins and has wires that make a magnetic field. The stator stays still and holds the magnets and brushes. The commutator, connected to the rotor, helps move electricity with the brushes.
Part | What It Does |
|---|---|
Rotor | Spins and makes a magnetic field. |
Stator | Stays still and holds magnets and brushes. |
Commutator | Moves electricity between the rotor and brushes. |
Brushes | Carry electricity to the commutator. |
Magnets | Create the magnetic field for the motor to work. |
Brushed motors use strong materials like samarium-cobalt or strontium ferrite for magnets. These materials help the motor work better and save energy. They can be up to 90% efficient when used correctly. Their simple design makes them easy to fix and dependable.
How Brushed Motors Work
Brushed motors use electromagnetism to work. When electricity flows, it goes through the brushes to the commutator and rotor wires. This makes a magnetic field that pushes against the stator’s magnets. The push makes the rotor spin. You can change the spin direction by switching the electricity’s polarity.
But, the fast switching of electricity in the commutator can cause noise and uneven spinning. This can make controlling the motor harder in some cases. Still, their simple design makes them useful for many jobs.
Main Features of Brushed Motors
Brushed DC motors have many good points that make them useful. They are small, light, and save energy because of their magnets. They start with strong power and are easy to control, which is great for precise tasks. They are also cheap and can run on simple batteries.
Feature Type | Details |

Brushless DC Motors: Features and Applications
How Brushless Motors Are Made
Brushless DC motors are carefully designed to work well and last long. The stator is made of steel layers and has windings in star or delta shapes. These shapes affect how much power and speed the motor can give. The rotor has strong magnets with many poles, which control the motor’s speed and power.
Unlike brushed motors, brushless ones don’t need brushes or a commutator. This design reduces damage and helps the motor last longer. Special sensors, like Hall sensors, are added to guide the motor. These sensors help the motor adjust to different tasks, making it run smoothly.
Nota: No brushes mean the motor lasts longer, is quieter, and works better.
How Brushless Motors Work
Brushless motors use electronics instead of brushes to work. Electricity flows through the stator windings, creating a magnetic field that spins the rotor. A controller changes the current to keep the motor’s speed and power steady.
The motor adjusts when the load gets heavier. If the motor slows down, increasing the voltage can bring back its speed. This control helps the motor perform well in many situations.
Main Features of Brushless Motors
Brushless motors have many benefits that make them special:
High Efficiency: They save energy by turning more electricity into movement.
Longer Lifespan: No brushes mean less wear, so they last longer.
Low Noise: They are quieter because there’s no brush friction.
High Torque-to-Weight Ratio: They give strong power without being heavy.
Reduced Maintenance: No brushes to replace means less upkeep.
Feature | Motor cepillado | Motor sin escobillas |
|---|---|---|
De por vida | Shorter | Longer |
Maintenance Requirements | Needs frequent fixes | Needs very little |
Eficacia | Baja | Higher |
Noise Levels | Louder | Quieter |
These features make brushless motors a top choice for jobs needing precision, energy savings, and reliability.
Advantages of Brushless Motors
Brushless motors have many benefits, making them popular in industries. They don’t use brushes, so they last longer and need less fixing. This makes them more reliable and easier to maintain over time.
Another big advantage is energy savings. Brushless motors turn more electricity into movement, wasting less energy. The International Energy Agency (IEA) says these motors could lower global electricity use by 10% by 2030. This makes them a great choice for eco-friendly and long-running tasks.
They are also very quiet. Without brushes, they make less noise, which is perfect for quiet places like hospitals or smart homes. Their smooth running also reduces shaking, making them more comfortable to use.
Here’s a table comparing brushed and brushless motors:
Factor | Brushed Motors | Brushless Motors |

Performance Comparison: Brushed vs. Brushless Motors
Efficiency and Energy Use
Brushed and brushless motors work differently in saving energy. Brushless motors are better at turning electricity into movement. They waste less energy, making them great for saving power. Brushed motors lose more energy because of friction from their brushes.
Brushless motors also work well with different voltage levels. This keeps them steady and reliable in changing conditions. For example, advanced systems like free-piston engine linear generators (FPELG) show how efficient designs save energy. These systems lose less than 5% of energy to friction, proving brushless motors are energy-efficient.
Lifespan and Strength
How long a motor lasts is very important. Brushless motors last much longer than brushed ones. They can run for 20,000 to 25,000 hours, while brushed motors last about 1,500 hours. Brushless motors don’t have brushes, so they wear out slower. This makes them a strong choice for tough jobs needing high power.
Both types of motors have been tested for strength. Tests show both can work for 10,000 hours without breaking. But brushless motors need less fixing, making them better for long-term use.
Noise and Smooth Running
Quiet motors are important in places needing low noise. Brushless motors are quieter than brushed ones because they don’t have brushes. No brushes mean no friction noise, which is great for medical tools and smart devices.
Motor noise can come from unbalanced parts or worn bearings. Brushless motors solve this with better designs that reduce shaking. Using good bearings and controlling gaps also lowers noise. These features make brushless motors smooth and quiet, perfect for sensitive jobs.
Cost and Affordability
When comparing these motors, cost is a big difference. Brushed motors are cheaper at first. For example, electric skateboards with brushed motors cost less than brushless ones. Brushed die grinders are also more affordable, making them good for tight budgets. But, they need more maintenance, which adds to costs later.
Brushless motors cost more upfront because they use better technology. However, they last longer and need less fixing. This saves money over time. For instance, brushless die grinders work longer and break less often. They also use energy more efficiently, lowering overall expenses.
Your choice depends on your budget and needs. If you need something cheap for now, brushed motors are fine. But for long-term savings and better performance, brushless motors are the better pick.
Maintenance and Reliability
How much care a motor needs is important. Brushed motors need regular maintenance. Their brushes wear out from friction and must be replaced. This can cause delays and extra costs. While brushed motors work well for simple jobs, they aren’t great for tough tasks.
Brushless motors are better for reliability and need less care. They don’t have brushes, so there’s no wear from friction. This means fewer repairs and steady performance. Brushless motors are great for high-efficiency jobs, like running medical tools or factory machines. They are dependable and require little upkeep.
