Brushed DC motors are designed for cost reduction through comprehensive in-house manufacturing. A wide range of sizes is available to suit various applications, including round types from 24 mm to 35.7 mm, oval types from 8 mm to 24.2 mm, and square types (S series) from 8 mm to 30 mm. The square S series achieves twice the torque within the same volume footprint, delivering a compact, lightweight, high-torque, and quiet design. Furthermore, the square architecture utilizes the space in the four corners to achieve miniaturization, enabling space-saving installation.
Alongside standard products, the lineup features high-torque models equipped with gearboxes and vibration motors that generate vibration via the centrifugal force of a weight. Specifications, torque characteristics, and overall views for each product are detailed in the downloadable "Product Catalog".
Customizations for brushed DC motors, such as the integration of gearboxes, weights (vibration motors), or encoders, are also available. For more information, see Engineering Information > Rotary Components > Technical Column in the top main menu.

FAQ
Where are brushed DC motors used in multi-function printers (MFPs)?
They power paper feeds, move ink cartridges and scanner heads, and operate trays.
They are ideal for applications requiring simple unidirectional or reciprocating motion.
What are the advantages of choosing a brushed DC motor over a brushless one?
The primary advantage is its simple configuration, which requires no motor driver.
They operate simply by connecting them to a DC power supply, and speed is easily controlled by varying the voltage via PWM. This reduces costs and saves PCB space. As long as they meet your required lifespan, brushed DC motors are the more cost-effective choice.
How can the lifespan of a brushed DC motor be extended?
Effective measures include operating within rated limits, providing rest periods, and adding capacitors.
Fundamentally, you must adhere to specifications by avoiding excessive loads and overcurrent. Adequate rest periods prevent overheating, while adding capacitors absorbs sparks that degrade the contacts, ultimately extending the motor's life.
How can I reverse the rotation direction of a brushed DC motor?
Simply swap the positive (+) and negative (-) terminals (polarity reversal).
The ability to change direction without complex electronic circuits is a key advantage.
Can a brushed DC motor be run directly from a household AC outlet?
No. As the name implies, they operate on direct current (DC).
You must convert alternating current (AC) to DC using an AC adapter or similar device before connection.
