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.

All About DC Gear Motors – High Torque Motors for Robotics & DIY Projects

Motor Selection Chart: Torque vs RPM

Common Applications: Robots, Automation & 3D Printers

Frequently Asked Questions

1. What is a geared DC motor?

2. How to use a gear motor?

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

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.
