Product description: N20-BT38 micro 250:1 120 RPM motor - 9V
Small, lightweight yet powerful, the N20 series of Pololu-compatible motors are used by robot builders as drive units. The units can be powered by up to 9 V (depending on the model), and gain their useful power above 3 V. The optimum voltage, at which the ratio of power to strength is most favourable, is 6 V.
Dimensions of the motor
The motor body is a cuboid measuring 24 x 10 x 12 mm. The gearbox is 9.27 mm long. There is a 3 mm D-shaped shaft at the output. Total mass is about 10 g.

Accessories compatible with the N20 series
N20 motors are compatible with Pololu motor accessories.
- Mounts: Special mounts in white or black have been designed for mounting the motors. An extended version and one made of high-strength aluminium are also available.
- Wheels, tracks, hubs: We also offer wheels and tracks to match the micro shafts of Pololu engines. Installation of non-standard wheels is facilitated by adapters.
- Motor controllers: Direction and speed control is provided by DC motor controllers. We offer integrated circuits for individual soldering as well as ready to connect, cooperating with kits (e.g. Arduino) modules.
