Kunstoffgetriebe Motor mit einer Übersetzung von 120:1.
Die Welle hat einen Durchmesser von 3mm und bei 4,5V Versorgungsspanung eine Lehrlaufdrehzahl von 120 UpM.

This compact, inexpensive, low-current gearmotor (brushed DC motor with a 120:1 reduction gearbox) is well suited for use in small robots. At 4.5 V, it has a free-run speed of 120 RPM and a stall torque of approximately 20 oz-in (however, the built-in safety clutch might start slipping before the stall torque is reached). The D-shaped output shaft has a diameter of 3 mm and works with the Pololu wheels and 3mm universal aluminum mounting hub. This gearbox output shaft is perpendicular to the motor shaft.

This brushed DC gearmotor is very compact and weighs only 0.7 ounces (19.5 grams) — perfect for building a quick, miniature robot. 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, the motor has a free-run current of 80 mA and a stall current of 800 mA; this relatively low current draw makes this a great match for our qik 2s9v1 dual serial motor controller and programmable Orangutan robot controllers. 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.

This gearmotor features a 3 mm D-shaped output shaft that matches those on our micro metal gearmotors and works with the Pololu wheels and 3mm universal aluminum mounting hub:

The gearbox output shaft is perpendicular to the motor shaft.

Gearmotor Versions

This gearmotor is available with two different output shaft orientations—offset from but parallel to the motor shaft or perpendicular to the motor shaft—and in two gear ratios—120:1 (for higher speed) or 180:1 (for higher torque). The 120:1 gear ratio versions are also available with a 2mm-diameter spline output shaft that can be used with custom wheels or our adapter for LEGO wheels. In all, we offer six different versions of this gearmotor:
