Product description: Motor Polol MP 75:1 double-sided shaft
Polol's small, lightweight yet powerful engines are used as drive units by robot constructors. The units can be supplied with voltage up to 9 V, the useful power is above 3 V. The optimum voltage at which the power to strength ratio is best is 6 V. This version has an extended shaft with a length of 4.5 mm, allowing the installation of speed sensors - encoders.
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 Polol micro motor with gearbox.
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.
