120:1 Mini Plastic Gearmotor, 90° 2mm Spline Output

120:1 Mini Plastic Gearmotor, 90° 2mm Spline Output.
This compact, inexpensive, low-current gearmotor (brushed DC motor with a 120:1 reduction gearbox) is well suited for use in small robots. While intended for operation at 4.5 V, it should run comfortably in the 3 V to 6 V range. The splined output shaft has a crest diameter of 2 mm and is perpendicular to the motor shaft. The gearbox is protected by a built-in safety clutch that helps protect the gears from excessive loads.

Specifications:

• Voltage: 4,5V
• no load performance: 120 RPM, 80 mA
• stall extrapolation: 1.4 kg⋅cm (20 oz⋅in), 800 mA
