Nowadays, servomotors and servomashinki are the most basic and often used part of all people who are engaged in modeling moving vehicles. Management of moving details without such an adaptation is not that difficult, but almost impossible.
Now, as for the motors themselves
Servomashinki can be found a variety of, a variety of capacities and rotation angles. Yes, and there are also many sizes, from small mini-motor to large, for huge models. Most often, standard views are found. Such servomashinki are manufactured for models performed on a 1:10 scale. But if you want to make a big and powerful or small and elegant model, do not be upset. After all, as mentioned above, the models have all sizes, for all the needs of the consumer. Their power is measured in units of sec/city. That is, the time for which they will turn the shaft to a given angle. For aircraft air models, there are special types for chassis. In such servomashins, the angle of rotation of the shaft is mainly in the range of 190 degrees. Their working voltage fluctuates from 4.8 to 6 volts, depending on the model.
If you need servomashinki for management, that is, steering, then when choosing data, you will need to pay attention to the material from which they are made by the reducer of such a servomashinka and the type of case. Corps for them are of two types: shock -resistant and moisture resistant. Servomashinki in shock -resistant housings are used mainly on car or aircraft models, where collisions often occur. Moisture -resistant species are used for models of boats, boats, yachts or other water vehicles.
Behind the control signal, they are divided into analog and digital. Digital models are put mainly in case of need to obtain the full effect of the servo drive, a special microcontroller is also sewn in them for the performance of complex actions. The advantage of digital machines is that they have a rapid response and accurate positioning of the shaft, but due to high cost they are used only in complex mechanisms, where accuracy and reaction are weight. Standard servomes have a low price range, which allows us to rationally use them in simple mechanisms that require less attention.
