Types of 12V Motors
Brushed DC Motors
How they work
Brushed DC motors are one of the simplest 12V motors. They use brushes and a commutator to move electricity to the rotor. When power flows, the brushes touch the commutator, making a magnetic field. This field spins the rotor, creating movement. These motors are easy to use and fix, so they are very popular.
Common applications
Brushed DC motors are found in toys, small gadgets, and cars. For example, they help move car windows and run windshield wipers. They are cheap and dependable, which makes them great for everyday tasks.
Fun fact: In 2023, the car motor market was worth over $36 billion. Brushed motors were a big part of this growth.

DC Brushless Motor | Uses electronics for better performance. | Robots, drones, electric cars |
Moteur à courant continu brossé | Simple design with brushes for power flow. | Toys, small gadgets |
Coreless DC Motors
How they work
Coreless DC motors don’t have an iron core in the rotor. This makes them lighter and faster to start spinning. Without the iron core, they also run smoother and with less noise.
Common applications
Coreless DC motors are great for jobs needing speed and accuracy. They are used in robots, medical tools like blood pumps, and space equipment. Their light design is perfect for satellites and other space uses.
Coreless motors are fast, quiet, and smooth, making them ideal for advanced tech.
Selection Criteria for 12V Motors
Torque Requirements
What is torque?
Torque is the twisting force that makes things spin. In a 12V motor, it shows how much weight the motor can move. It is measured in Newton-meters (Nm) and affects how well the motor works. A motor with more torque can handle heavier tasks or push through resistance. For example, a conveyor belt needs a motor with enough torque to move items smoothly without stopping.
Choosing the right torque
Pick a motor with torque that fits your task. Think about things like friction, slopes, and how fast you need it to start. Use charts to check if the motor’s torque matches your needs. Remember, when speed goes up, torque goes down. This balance is important to keep the motor working well without overheating or breaking too soon.
Parameter | What It Means |
|---|---|
Torque and Speed | |
Inverse Relationship | When speed rises, torque drops. |
Application Needs | Torque depends on friction, slopes, and how fast you need it to move. |
Speed and RPM
Why speed matters
Speed, measured in revolutions per minute (RPM), shows how fast the motor spins. It’s important for tasks needing quick or precise movements. For example, a robotic arm needs high speed to move fast but must stay accurate. The formula for power is: Power = Torque x RPM / 5252. This shows how speed and torque work together to give the needed power.
Finding the right RPM
To pick the right RPM, think about what your task needs. For example, a fan motor needs steady speed to move air well. Compare the motor’s speed to what you want it to do. Charts can help you see how speed and torque affect each other. Knowing this helps you choose a motor that works well without wasting energy.
Efficiency and Power Use
Why efficiency is important
Efficiency shows how well a motor turns electricity into movement. A better motor wastes less energy, saving money and power. In 2020, motors were 88.8% efficient, up from 85.7% in 1990. This improvement helps industries by cutting pollution and making devices last longer.
Balancing power and performance
When picking a motor, balance how much power it uses with how well it works. A motor that uses less power might not be strong enough for your task. For example, 12V motors in electric cars focus on saving energy to go farther while staying powerful. Look for motors that save energy and work well to save money over time.
Power Use Range | Future Revenue Impact by 2032 | Main Goals |
|---|---|---|
3V-12V | Big revenue growth expected | Save energy, cut pollution, improve electric car range |
Tip: Always check the motor’s efficiency and power use to match your needs and make a smart choice.
Environmental Considerations
Operating temperature and conditions
Think about where the motor will work. Temperature affects how well it runs. Hot weather can make it less efficient. Cold weather might slow it down. High places with thin air can also change how it works. Motors need to handle these challenges to stay reliable. Wind and sunlight can wear out materials too. For example, UV rays can damage parts over time. Testing motors in these conditions helps ensure they work properly.
Important environmental tests include:
Checking performance in high-altitude, low-air-pressure areas.
Testing stability in windy conditions.
Measuring how materials hold up under UV light.
Durability and material considerations
How long a motor lasts depends on its materials. Strong materials resist damage and last longer. Motors used outdoors or in factories must handle tough conditions like dust, water, and shaking. Picking a motor made with rust-proof materials helps it work well in harsh places. Always check the motor’s details to match its strength to your needs.
Size and Weight
Compact designs for space-constrained applications
Some devices don’t have much room inside. Small 12V motors are perfect for tight spaces. They fit well without losing power. For example, tiny motors in robots help small arms move precisely. When choosing a motor, find one that is small but still powerful.
Weight considerations for portable devices
Weight matters for things you need to carry. Light motors make devices easier to move and use. For example, lighter motors in electric wheelchairs make them easier to handle. Always pick a motor that balances weight and power so it works well without being too heavy.
Cost and Budget
Balancing cost with performance
Price is important when picking a motor. You need one that works well but doesn’t cost too much. Different motors are made for different jobs. For example, brushed motors are cheaper for simple tasks. Brushless motors cost more but work better for advanced uses. Knowing what you need helps you choose wisely.
Long-term cost-effectiveness
Think about future savings, not just the price now. Efficient motors use less energy, saving money on electricity. Strong motors last longer, so you spend less on repairs. For example, a good motor in factory machines can save money by needing fewer fixes. Always think about how much the motor will cost over time before buying it.
