Product description: N20-BT37 micro 210:1 140 RPM motor - 9V
Small, lightweight yet powerful motors from the N20 series, compatible with Pololu's 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.
The drawing shows the dimensions of the micro motor with gearbox.

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.
Attention! N20 motors are not compatible with Pololu micro motor encoders. |
