1. What is a geared DC motor?

A geared DC motor is a DC motor and gearbox. The gear box is used to reduce the speed while increasing the torque, giving the motor the ability to rotate more load than a traditional DC motor. A gear motor is any electric motor coupled with a gear train. It can be defined as a combination of motor and reduction gear train or it can also be defined as an extension of a DC motor.

2. How to use a gear motor?

Geared DC motors can be used just like regular DC motors. The only difference is that a geared motor will generally rotate slower but give better torque output, hence being able to provide more force with each turn. Gear motors are used in applications that require lower shaft speed and higher torque output. This means that it can be used for a wide range of applications and scenarios, including many of the machines and equipment we interact with on a daily basis.

3. What is the difference between a DC motor and DC geared motor? How do I choose a gear motor?

Geared DC motor is a regular DC motor coupled with a gearbox. The gearbox helps the motor provide more torque (rotational force), in favor of speed. A regular DC motor should be used in applications where speed is the priority while geared DC motor should be used in applications where torque is required (motors to lift heavy equipment)

4. How do we use the gearbox in a motor?

Gearbox is a built in component of the geared DC motor and the user does not have to specially set up or interface with it. The DC motor shaft connects to the gearbox and ends up rotating the gear shaft at a particular speed, for the given input speed. This ratio helps us determine the gear ratio

5. What is a gear reduction motor?

Gear reduction motor contains an arrangement of gears in such a way that the output speed is lowered in favor of more torque. Typically all geared motors contain a gear reduction set, and that is what helps the motor convert its speed to more torque.

6. What are DC gear motors used for?

DC gear motors are used to convert rotational motion from a DC motor into lower-speed, higher-torque output via a gearbox. On the collection page you’ll see that they’re described as “top-grade high-torque DC gear motors for DIY & robotic projects.” They’re ideal for driving wheels, arms, tracks, conveyors, and any mechanical motion where controlled speed + strong torque matter.

7. Which gear motor is best for robotics projects?

The best gear motor for a robotics project depends on the robot’s load, speed and space constraints. For small wheeled robots, a mid-RPM (100-300 RPM) high-torque geared motor is often optimal. For example, the site lists a “12V 300 RPM-geared motor” as suitable. If you need high torque for lifting or pushing, choose a lower RPM gear ratio so the motor delivers more force. If you need faster motion, pick a higher RPM variant with appropriate torque.

8. What torque and RPM ranges are available?

The collection offers a wide range of RPM ratings: for example you’ll find gears rated at 100 RPM, 150 RPM, 300 RPM and more. Torque values depend on gear ratio and motor size; some micro motors list ~2 kg-cm for ~100 RPM type. The key takeaway: you’ll find motors from low-RPM high-torque types up to higher-RPM lower-torque options in this collection.

9. Are these motors compatible with Arduino & Raspberry Pi?

Yes, they are compatible. These are standard DC geared motors (for example 12V versions) that you can control using motor driver modules connected to microcontrollers like Arduino or Raspberry Pi. The site describes them as “DIY & robotic projects” motors which implies microcontroller use. You’ll need a suitable driver board, power supply and ensure the motor’s voltage/current fits your system.

10. Do gear motors come with wheels or mounting brackets?

In many listings the motor is sold alone (just the geared motor). The collection page doesn’t guarantee that wheels or brackets are always included. For example, a motor is described simply as “300 RPM DC Geared Motor” without mention of wheels. If your project needs wheels or mounting brackets you should check the “Package Includes” section of each listing to see whether accessories are bundled or need to be purchased separately.

Motor Selection Chart: Torque vs RPM

Output Speed (RPM)	Approx. Output Torque*	Typical Use Case
~60 RPM	High torque (e.g., ~1–3 kg·cm)	Robot drive wheels, slow actuation, mobile platforms
~100 RPM	Medium-high torque (~0.6–1.5 kg·cm)	Small automation, robotics arms, mechanisms
~200–300 RPM	Moderate torque (~0.4–1.0 kg·cm)	Fast motion tasks, light duty conveyors, small car wheels
>300 RPM	Lower torque (~0.2–0.5 kg·cm)	High speed rotation, fans, toy-motors, lightweight drives

*Values are approximate and depend on gearbox ratio, motor voltage, and load. Use for guidance.

Common Applications: Robots, Automation & 3D Printers

Robotics: Drive robot wheels, arms or grippers using gear motors at ~60-100 RPM for good control and torque.

Automation: Conveyor belts, lifting platforms, actuator mechanisms where high torque and controlled speed are required.

3D Printers / Mechanisms: Use moderate-speed gear motors for filament feed, build platform motion or secondary movements where torque is needed but speed moderate.

Wiring & Connection Guide

Power supply: Match the motor’s rated voltage (e.g., 3 V, 6 V, 12 V) and ensure the power supply can handle the current.

Motor driver/bridge: Use an H-bridge (e.g., L298N) or MOSFET driver to control direction and speed (via PWM) since gear motors draw higher current especially at load.

Direction control: Wire “IN1/IN2” (or equivalent) on driver to microcontroller digital pins for reversing motor direction. Use “ENA/ENB” pins for enabling and speed control (via PWM).

Mounting the motor: Secure the motor body to your chassis using mount holes/brackets. Make sure the output shaft is properly aligned with wheels, gears or couplers to avoid misalignment or mechanical stress.

Shaft coupling & output: If using dual-shaft motors, mount wheels on both ends or use one end for output and the other for balancing. For single-shaft, ensure the shaft is connected neatly to gear, pulley or wheel.

Testing & safety: Test at low speed under no load first. Monitor motor for heating. If the motor stalls or overheats, reduce load, check gear ratio or supply.
