This gearmotor is a miniature high-power, 6 V brushed DC motor with long-life carbon brushes and a 4.995:1 metal gearbox. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. Pololu 3060

Miniature high-power motor from the Pololu MP series. Gear motor 5: 1,
the rotational speed of the shaft is 4400 rpm, the torque is 0.1 kg * cm (0.01 Nm).
The motor has an extended shaft which makes it easy to attach the encoder. Pololu 2376

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.

This tiny, cylindrical gearmotor consists of a coreless brushed DC motor and a 26:1 plastic planetary gearbox. The entire assembly has a diameter of just 6 mm (0.24″) and an extremely light weight of 1.2 g (0.042 oz), making it a great actuator for miniature robots and very small mechanisms.

Key specs at 6 V: 2500 RPM and 35 mA free-run, 1.5 oz-in (0.1 kg-cm) and 400 mA stall.

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

DC motor set with a two-sided shaft and a matching 66mm diameter wheel with the tire. HC02-48

This is the Wheel Encoder Kit from DAGU, a simple add-on to any wheeled robot that can help measure the speed or distance the chassis travels. ROB-12629

This two-part aluminum assembly mounts directly to 6 mm diameter motor output shafts like those on our 37D mm gearmotors and allows you to drive most scooter, skateboard, inline skate, and other common wheels that are compatible with popular 608 ball bearings.

Hybrid bipolar stepper motor eith integrated 18cm (7″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7A at 2.8V, allowing for a holding torque of 3.7kg-cm (51 oz-in). Pololu 2689

Compact engine with 75: 1 LP transmission, shaft speed is 290 rpm, torque is 0.8 kg * cm (0.08 Nm), plate with connector PH 2.0. DFRobot FIT0457

These 17 mm long aluminum adapters convert a 3 mm diameter shaft to a 12 mm hex shaft that compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four M3 set screws for securing the adapters to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.
