Torque and rotational speed - the most important operating parameters of servomechanisms

Geometric dimensions, own weight, operating range, supply voltage and control method are parameters that must also be taken into account when choosing a micro servo. As in larger counterparts, the final effect is determined by the torque and rotational speed of the servo. Torque describes how much mass the servo can move using an arm of a specific length - this arm is usually a pusher attached with one end to the servo's linkage and the other to the object controlled by the servo. The rotational speed of the servo is usually parameterized as the time needed to rotate the axis with the T-bar through an angle of 60°. This is a standard adopted by all manufacturers - however, remember to check the servo specifications before purchasing! If you are a beginner in robotics and need a servo to control, for example, the height of a small remote-controlled aircraft with a wingspan of less than 1 m, then it will be optimal to use a servo with a rotation speed of 0.17 s/60°. However, to control the tail rotor of a remote-controlled helicopter, it will be necessary to use a servo with a rotation speed of 0.05 s/60° to instantly counteract the torque of the main rotor.

How to control a servo from Arduino?

The process of controlling the servo directly from Arduino has a simple structure. It is best to connect the servo to Arduino via a dedicated shield, due to the fact that the current capacity of the GPIO outputs in Arduino may be insufficient in relation to the hardware requirements of the servo - the maximum operating current from a single Arduino output is 40 mA. Servomechanisms whose current consumption does not exceed the current capacity of the Arduino outputs can be connected directly. Then, the black servo wire should be connected to the ground pin (GND), the red wire to the supply voltage pin (+5 V), and the yellow wire to one of the pins giving a binary signal at the output. You can also connect the red wire to the pin set as a digital output, set to the logical high state, and the black wire to the digital output set to the low state. When using a servo whose current consumption exceeds the energy capabilities of the Arduino, use an external battery or power supply, but for proper and safe operation, the ground pole of the external voltage source must be connected to the ground terminal (GND) in the Arduino. Another method of controlling servos is to upload a dedicated "servo library" to the program code in the Arduino compiler. This library enables comprehensive control of servos. If you want to control a large number of servomechanisms, it is best to use an external controller and an independent power supply with an output voltage in the range of 4.8 V to 6.0 V.

Micro servos - FAQ

To properly match the servo to a specific RC car model, first of all, you should familiarize yourself with the technical parameters. This applies not only to torque, but also to speed, weight and dimensions. The materials from which the servo gears are made are also crucial. In the case of plastic (e.g. nylon), the servo is characterized by low weight. In turn, metal gears are able to transfer greater torque.

Choosing the right server tailored to the project requirements primarily involves adjusting operating parameters. To properly select a servo, you should pay attention to its geometric dimensions, supply voltage range, servo operating range and the way it can be controlled. The two most important parameters of servomechanisms are torque.

A servo drive is a system that is used to control not only speed, but also position. A servo drive is not a separate device, but a set that consists of a servo motor responsible for processing signals into a specific type of movement. Another element of the servo drive is the servo controller, a device whose main task is to communicate not only with the drive, but also with its power supply. In turn, the PLC controller is the master part that is responsible for sending signals containing commands.
