Brushed Motors: How 24 Volt DC Electric Motors Work
Key Components and Operation
You might wonder why brushed motors remain popular in so many industries. The answer lies in their straightforward design and reliable performance. When you use a 24 volt dc motor with brushed technology, you get a system that converts electrical energy into mechanical motion using a simple yet effective process. The main parts of a brush motor each play a specific role in making this happen. Here is a table that breaks down the key components and their functions:
Component | Function | Key Details |
|---|---|---|
Armature (Rotor) | Carries current and interacts with the magnetic field to produce torque. | Made of copper wire to reduce resistance. |
Rotates to deliver mechanical energy at the motor shaft. | Laminated iron core reduces eddy current losses. | |
Commutator | Reverses the current direction in the windings as the rotor turns. | Works closely with the brushes. |
Ensures that the armature torque remains unidirectional. | Ensures continuous current flow during rotation. | |
Brushes | Transfer electric current from the external circuit to the commutator. | Subject to wear and require regular replacement. |
The contact causes friction and sparking. | ||
Field Magnets | Establishes a magnetic field that interacts with the armature. | The stronger the magnetic field, the higher the torque. |
Shaft | Transmits rotational mechanical energy to the external load. | Often connected to gears, pulleys, or wheels. |
Bearings | Support the rotating shaft, allowing it to spin freely. | Typically ball or sleeve bearings. |
Motor Housing | Encloses and protects the internal components. | Made from aluminum or steel for strength and durability. |
Windings | Carry the electrical current that creates magnetic fields for motion. | Wound in specific patterns to maximize efficiency. |
Cooling System | Removes heat generated by current flow and friction. | May include fans, heat sinks, or air ducts. |
When you supply power to a brushed motor, the brushes press against the commutator. This action allows current to flow into the armature windings. The interaction between the magnetic field from the field magnets and the current in the armature creates torque. The shaft then spins, delivering mechanical energy to your application. The commutator and brushes work together to keep the rotation smooth and continuous.
Common Applications
You often see brushed motors in places where you need a balance of power, reliability, and cost-effectiveness. Here are some of the most common uses for a 24 volt brush motor:
Electric vehicles: You get dependable power for electric bikes, scooters, and small cars.
Robotics: Brushed motors handle heavy tasks and provide steady movement in robotic arms and platforms.
Medical tools: You find them in devices that require accuracy and reliability, such as pumps and surgical equipment.
Home automation: Brushed motors power systems like automated blinds, locks, and small appliances.
Green energy systems: You use them in solar and wind power setups to convert energy efficiently.
You choose brushed motors for these applications because they offer simple control, easy integration, and proven performance. The design of a brush motor lets you achieve reliable results without complex electronics. When you need a dc motor that works right out of the box, brushed motors often provide the best solution.
Brushless Motors: How 24 Volt DC Electric Motors Work
When you look at brushless motors, you see a different approach to creating motion. Brushless motors use electronic commutation instead of brushes. This means you get a system that switches the current in the windings as the rotor turns. The stator holds the coils, and the rotor uses permanent magnets. The interaction between these magnetic fields produces torque. Brushless motors rely on Lorentz’s force law. When current flows through the coils, it creates a magnetic field. This field interacts with the rotor’s magnets, causing rotation. The electronic controller changes the current direction, so the magnetic poles keep shifting. This process keeps the rotor moving smoothly. Unlike brushed motors, brushless motors do not use brushes or a commutator. You get less friction, less wear, and more efficiency. The method of commutation is the main reason why brushless motors last longer and need less maintenance.

Brushed vs. Brushless Motors: Performance Comparison
Efficiency and Power
You want your 24 volt DC electric motor to deliver high performance and reliable efficiency. When you compare brushed and brushless motors, you notice clear differences in how they use energy and produce power. Brushless motors stand out for their high performance, especially in demanding applications. They use electronic commutation, which reduces friction and energy loss. This design leads to higher efficiency and more consistent power output.
Take a look at the efficiency ratings:
Motor Type | Efficiency Rating |
|---|---|
Brushless Motors | 85-90% |
Brushed Motors | 75-80% |
You see that brushless motors convert more electrical energy into mechanical motion. This means less waste and lower operating costs. In real-world applications, such as INEED’s brushless gear motors for pool cleaners, you get high performance and energy efficiency. These motors help pool cleaners climb stairs and handle debris without losing power. Brushed motors, while reliable, cannot match the efficiency or high performance of brushless designs. You might choose brushed motors for simple tasks, but when you need high performance and energy efficiency, brushless motors are the better choice.
Durability and Maintenance
You want your motor to last as long as possible with minimal maintenance. Brushless motors excel in this area. They do not have brushes that wear out, so you get a longer lifespan and less frequent maintenance. Here is a comparison of average lifespans and working hours:
Motor Type | Average Lifespan (Years) | Average Continuous Working Hours |
|---|---|---|
Brushless Motors | 7 to 10 | 20,000 to 30,000 |
Brushed Motors | 2 to 3 | 1,000 to 5,000 |
Brushless motors typically last between 7 to 10 years and can operate for 20,000 to 30,000 hours. Brushed motors have a lifespan of only 2 to 3 years, with 1,000 to 5,000 hours of continuous use. You also need to consider maintenance requirements:
Motor Type | Maintenance Requirements | Impact on Cost of Ownership |
|---|---|---|
Brushed Motors | Regular inspection of brushes and commutator, replacement of brushes, cleaning commutator, lubricating bearings, checking electrical connections | Higher long-term costs due to frequent maintenance and potential downtime |
Brushless Motors | Minimal maintenance, occasional bearing checks | Lower long-term costs due to reduced maintenance needs and longer lifespan |
You spend more time and money maintaining brushed motors. You need to replace brushes, clean the commutator, and check for wear. Brushless motors require only occasional bearing checks. This low maintenance design saves you time and money. For example, INEED’s brushless motors in electric dental handpieces provide high performance and reliability with minimal maintenance, making them ideal for healthcare environments.
Cost and Value
You want to know which motor gives you the best value over time. Brushed motors have a lower initial cost, so you might choose them for budget-sensitive projects.
