AI Overview
These are 12V DC motors with gearboxes; the main choice is output speed, torque, and whether you need an encoder.
- High torque, low speed: Metal DC Geared Motor – 12V 50RPM 50kg.cm has a 100:1 metal gearbox and 50 kg·cm stall torque ($20.95).
- Budget options without encoders: 12v JGA25-370 DC speed reduction motor 60 RPM and 12v JGA25-370 DC speed reduction motor 280 RPM are $8.80 each.
- With speed feedback: 12V GA25-370 DC Gear motor with Speed Encode 60 RMP and 12V GA25-370 DC Gear motor with Speed Encode 280 RMP include encoders ($16.45 each).
- Higher-spec choices: 47:1 Metal Gearmotor 25Dx52L mm HP 12V runs at 220 RPM no-load ($44.05); Metal DC Geared Motor w/Encoder – 12V 122RPM 38Kg.cm combines a 90:1 gearbox with a quadrature encoder ($47.70).
