The 1122-POLOLU is a mini size, inexpensive low current DC brushed gearmotor perfect for building quick small robots. 

The recommended operating voltage range for this motor is 3 to 6 V, though the gearmotor can start rotating at voltages as low as 0.6 V. At 4.5 V, it has a free-run speed of 120 RPM and a stall torque of approximately 20 oz-in. The motor at 4.5V has a free-run current of 80 mA and a stall current of 800 mA. The stall current, torque, and rotation speed will approximately scale linearly with the motor voltage. The gearbox is protected by a built-in safety clutch that will typically slip before gear teeth can shear.

Features:

  • Typical operating voltage: 4.5V
  • Gear ratio: 120:1
  • Free-run speed/current @ 4.5V: 80 rpm/80 mA
  • Stall current/torque @ 4.5V: 800 mA/30 oz·in

The splined output shaft has a crest diameter of 2 mm and is offset from but parallel to the motor shaft.
