Servo motor projects8/10/2023 ![]() So, in this article, we are going to see What is a Servo Motor? How does it work? Types of Servo Motors and Applications where it is used.Ī servo motor is an electric motor that can rotate with great precision and high efficiency. Servo Motors are the perfect mechanism to achieve these accurate movements. In all these applications one thing is common that the precise and accurate linear and angular movements. There are plenty of other applications like automatic door opening/closing, antenna positioning, solar panel movement, etc. We often see printer printing a paper and see the accurate movement of the printing head on the paper to write or draw. Like the servo size, simply make sure the shaft accessories you choose match the spline type of your servo.We have seen the working of robotics arms in many industries and most of us thought that how these arms move very precisely. Depending on your servo, you may see something like “C1 Spline” for a standard Hitec servo or possibly “3F Spline” for a standard Futaba one. Servo manufacturers like Hitec and Futaba have several types of splines for their various servo classes. Just remember when choosing an accessory for your servo to make sure it will work with your servo’s size.Ī Servo’s Spline Size refers to the size and number of “teeth” on the output shaft. We covered servo sizes in the previous section so we’ll focus on Servo Splines here. There are two important factors to consider when choosing a servo accessory: Spline Size or Spline Count and Servo Size. ![]() From shaft extensions to gripper kits and pan-tilt brackets, there are all sorts of hardware and components you can add to your servo to augment and improve its functionality. It is worth noting that any measurement between no load and the stall torque spec will more than likely slow down the operating speed listed.Ī servo on its own cannot do much so accessories connected to the drive shaft are necessary to get the most out of your servo. 16 seconds with no load, and has a higher torque limit of 4.1kg/cm. At 6V, the high end of the test voltage, the servo can move 60° at a speed of. Also operating at 4.8V, this servo motor can drive a load up to 3.3kg/cm ( Stall Torque). 21 seconds without any limiting force factors (load). The datasheet shows that at 4.8V the servo can move 60° at a speed of. The first thing to notice is that this servo lists a Test Voltage, often labeled Operating Voltage, from 4.8V to 6V. We've pulled out a few key power specs from this datasheet for the Hitec HS-422 (Standard Size) servo. Let's take a look at an example :Īn exerpt from a datasheet for the Hitec HS-422 It is important to check the specifications of the servo you intend to use to make sure your power supply has the proper voltage range and can deliver enough current to move the servo with your load attached. ![]() When unloaded, a common hobby servo can pull as little as 10mA, but larger servos under load can pull in excess of an Ampere or more. More important than voltage is the current draw a servo can pull while moving and with a load attached. Depending on the size and torque output of your servo the input voltage will vary, but most hobby servos will work fine with 5V from your preferred microcontroller or battery circuit.
