Product description: N20-BT18 micro 5:1 250RPM 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.
The drawing shows the dimensions of the micro motor with gearbox.
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.
