DC motor with 1:48 plastic gearbox. equipped with incremental encoder with Hall sensors. Includes bracket, mounting hardware and cord

Tiny, cylindrical gearmotor consists of a coreless brushed DC motor and a 136:1 plastic planetary gearbox. 500 RPM and 45 mA free-run, 8 oz-in (0.6 kg-cm) and 400 mA stall. Pololu 2358

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.

DC motor with 1:84 planetary gear with a supply voltage from 6 to 24 V and a rotational speed of 140 RPM. Maximum current consumption up to 1.3 A. SparkFun ROB-15277

DC motor equipped with a plastic gear 48:1 with a cut shaft on both sides and an additional shaft for connecting an encoder

This compact, inexpensive plastic gearmotor (high-power 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.
