700:1 Sub-Micro Plastic Planetary Gearmotor 6Dx21L mm

This tiny, cylindrical gearmotor consists of a coreless brushed DC motor and a 700:1 plastic planetary gearbox. The entire assembly has a diameter of just 6 mm (0.24″) and an extremely light weight of 1.3 g (0.046 oz), making it a great actuator for miniature robots and very small mechanisms.

Key specs at 6 V: 90 RPM and 45 mA free-run, 12 oz-in (0.9 kg-cm) and 400 mA stall.
