These are a pair of hobby gearmotors from DAGU. These gearmotors are the same ones recommended for use in the Shadow Chassis and offer a cheap and easy-to-use setup to get your wheels turning. Each Hobby Gearmotor also possess a 9mm long output on a straight axis.
These gearmotors require a voltage of 4.5V with a no load current of 190mA while possessing a gearbox ratio of 48:1 and a wheel speed of 140 RPM unloaded.
Every motor order is sold in packs of two.
Note: The RPM listed in the datasheet below is listed as 90RPM. Based on our own testing we found the gearmotors can actually achieve a No Load Speed of about 140 RPM.
Features:
- Suggested Voltage: 4.5VDC
- No Load Speed: 140RPM
- No Load Current: 190mA
- Max. Load Current: 250mA
- Torque: 800 gf-cm

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
