Description
The small, lightweight yet powerful N20 series engines, compatible with Polol's engines, are used as drive units by robot constructors. The units can be powered up to 9 volts (depending on the model), the useful power is over 3 volts. The optimum voltage at which the power to strength ratio is best is 6 V.
Motor dimensions
The motor body is a 24 x 10 x 12 mm cuboid. The gearbox is 9,27 mm long. There is a 3 mm D-shaped shaft at the output. Total weight is about 10 g.
The drawing shows the dimensions of the micro motor with the gearbox.
Accessories
The N20 motors are compatible with Polol motor accessories.
- Mountings: For mounting the motors, special mountings in white orblackare designed. Anextendedversion is also available, as well asaheavy-dutyaluminium version.
- Wheels, crawlers,hubs:Wealso offer wheels and crawlers, matching Pololmicroengine shafts. Installation of non-standard wheels is facilitated by adapters.
- Motor Controls:Direction and speedcontrolare provided by DC motor controllers. We offer both self-solderingintegratedcircuits and ready-to-connect, cooperating with sets (e.g. Arduino) modules.
