A 200:1 plastic gearmotor with a 90-degree output shaft, offering a compact and affordable solution for small robot designs. The low-current brushed DC motor is well-suited for use with common motor drivers, and the recommended operating voltage range is 3–12V.
The gearbox is fully enclosed and protected by a built-in safety clutch that slips before gear teeth can shear, preventing damage during stall conditions. The output shaft is 6mm long and 7mm in diameter with two flattened sides.
Key Features
- 200:1 Gear Ratio – Higher torque, lower speed configuration
- 90° Output Shaft – Output shaft perpendicular to motor axis
- Built-in Safety Clutch – Protects gears from damage during stalls
- Pre-Assembled – Ready to use with fully enclosed gears
- Compact Size – Ideal for small robot platforms
- Two Mounting Holes – Compatible with L-bracket mounting
Specifications (at 6V)
- Gear Ratio: 200:1
- Operating Voltage: 3–12V
- No-Load Speed: ~51 RPM
- Stall Torque: ~100 oz·in
- Free-Running Current: 70mA
- Stall Current: 800mA
- Output Shaft: 7mm diameter × 6mm long, dual-flat
- Output Angle: 90° from motor axis
Ideal For
- Small robot platforms and drivetrains
- Low-speed, high-torque applications
- Educational robotics kits
- Battery-powered mobile projects
Package Contents
- 1× 200:1 Plastic Gearmotor (90° output, pre-assembled)
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
