Accessories
We offer a range of accessories that work with Polol's micro motors:
- Fixings
Special fixtures in white orblackhave been designed for mounting the motors. Anextendedversion is also available, as well asan aluminium version withincreasedstrength.
In the case of micro 1000:1 and 1000:1 HP motors, the mountings do not cover the entire gearbox.
- Wheels, crawlers, hubs,Encoders
Our offer also includes wheelsand tracks,matched to themicro engine shafts of Polol. There is also a special version of wheels with speed measuring encoders available. Installation of non-standard wheels is facilitated by adapters.
- Engine drivers
Direction and speed control are provided by DC motor controllers. In our offer there are bothintegratedcircuitsforself-soldering and ready to connect, cooperating with sets (e.g. Arduino) modules.
There are many otherenginesin the shop's offer.
