A compact all-metal DC gearmotor family from DFRobot, sold here as one motor in seven gear ratios. Every version shares the same 6 V brushed motor, the same 4 mm D-shaped output shaft and the same mounting footprint — the only thing that changes is the gearbox, which trades speed against torque from a slow, very strong 15 RPM / 10 kg·cm right through to a brisk 357 RPM / 0.7 kg·cm.
Metal gears throughout give these a much longer life than the plastic-gearbox motors they compete with, which is why they hold up in classroom robots that get rebuilt every term. Pick the ratio by the job: high torque for lifting, driving loaded wheels and pan-tilt mechanisms; high speed for light drive wheels and anything that needs to actually get moving.
Compare the seven speeds
All seven are the same price and the same physical motor. No-load speed is measured at 6 V; torque figures are locked-rotor (stall).
| Speed | Stall torque | Gear ratio | Gearbox length | No-load current | Weight | SKU |
|---|---|---|---|---|---|---|
| 15 RPM | 10 kg·cm | 478:1 | 27 mm | 50 mA | 74 g | DF-FIT0495-A |
| 20 RPM | 7.5 kg·cm | 362:1 | 27 mm | 50 mA | 74 g | DF-FIT0495-B |
| 73 RPM | 2.5 kg·cm | 99:1 | 23 mm | 50 mA | 72 g | DF-FIT0495-E |
| 97 RPM | 1.9 kg·cm | 75:1 | 23 mm | 50 mA | 70 g | DF-FIT0495-F |
| 162 RPM | 1.2 kg·cm | 45:1 | 21 mm | 50 mA | 68 g | DF-FIT0495-G |
| 191 RPM | 1 kg·cm | 34:1 | 21 mm | 60 mA | 68 g | DF-FIT0495-H |
| 357 RPM | 0.7 kg·cm | 20:1 | 19 mm | 50 mA | 66 g | DF-FIT0495-I |
Which one should I pick?
| If you are building | Choose |
|---|---|
| A lifting arm, winch or geared-down joint | 15 RPM · 10 kg·cm |

| A loaded robot chassis | 73 RPM · 2.5 kg·cm |
| A small two-wheel drive robot (the usual pick) | 97 RPM · 1.9 kg·cm |
| Quicker drive wheels that still need pull | 162 RPM · 1.2 kg·cm |
| A line-follower or light chassis that needs pace | 191 RPM · 1 kg·cm |
| The fastest option, for light loads only | 357 RPM · 0.7 kg·cm |

A note on driving them
These are plain two-wire brushed DC motors with no encoder and no built-in driver — you will need an H-bridge motor driver to run one from a microcontroller. Stall current is 0.6 A per motor, so size the driver and supply for the number of motors you are running simultaneously. If you need closed-loop speed or position control, look at the encoder versions of this motor instead.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
- kg·cm
- A torque unit often used for hobby servos, meaning how many kilograms of force the servo can hold at a 1 cm arm length. A higher kg·cm rating means the servo can move or hold heavier loads, but power supply current needs may also increase.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- Stall torque
- The maximum twisting force a servo can produce when its output is held still and cannot move. It helps you judge whether the servo is strong enough for a robot joint, steering linkage, or other load.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
