his compact, inexpensive plastic gearmotor (brushed DC motor with a 180:1 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 gearbox has a 9.7mm-long, 3 mm-diameter D-shaped output shaft that is perpendicular to the motor shaft, and a built-in safety clutch helps protect the gears from excessive loads.

Key specs at 4.5V: 80 RPM and 80 mA free-run, 30 oz-in (2.2 kg-cm) and 0.8 A stall.

Specifications:

  • Size: 54.5 x 20 x 13.8mm
  • Weight: 19.5g
  • Shaft diameter: 3 mm
  • Shaft type: 90° 3mm D
  • Typical operating voltage: 4.5V
