Collection: Servo Motors

Servo Motors - Servo Motors are simply electric motors that are controlled for specific angular rotation with the help of an additional servomechanism. Generally, these motors do include DC and AC motors. They are used in a closed-loop mechanism that registers its position feedback to control its rotational speed. For control purposes, servo motors consist of large industrial applications. They are majorly seen in remote-controlled toy cars to monitor motion. As the motor moves its tray, these are also used in CD or DVD players. Servo motors are being used in our daily lives.

Simple servo motors use DC motors and position them accordingly through a potentiometer. Until and unless it is stopped at a designated position, a servo motor moves at high speed or by the controller. In radio-controlled devices such as model aircraft and toy cars, these kinds of servo motors are a favorite. As the speed of the shaft can also be controlled, the engine gets to its position quickly without any fail, because they also impose the proportional-integral-derivative control algorithms

Purpose of Servo Motors

Used to rotate and push parts of a machine with precision, servo motors or “servos”, as they are known, are electronic devices and rotary or linear actuators. Servos are mainly used on angular or linear positions and for specific velocity, and acceleration.

Because of how compact and potent it is, companies heavily use servo motors. It is known to be incredibly energy-efficient, as it generates quite the amount of power.

To position control surfaces and rotate objects at precise angles and distances, most of the companies that use servos are manufacturing companies that need it.

Two Types of Servo Motors

In the industrial field, two types of servo motors are available and used:

First is the AC servo motor. Most of the companies use this type of servo motor these days.  In industrial fields, these kinds of motors are being used. AC servo motors are AC motors that rely on encoders. Providing feedback and closed-loop control, these types of servo motors work through controllers. They are known to function with high accuracy and are easily controllable.

The second is the DC servo motor. AC servo motors are easier to use, more effective, advanced, and reliable.

Servo Motor Applications

To fully understand what a servo motor is, it’s also important to understand its applications. Servos are used in radio-controlled airplanes to position control surfaces like elevators, rudders, walking robots, or grippers. They are small, have built-in control circuitry, and have good power for their size.

In food services and pharmaceuticals, the tools are designed to be used in harsher environments, where the potential for corrosion is high due to being washed at high pressures and temperatures repeatedly to maintain strict hygiene standards. Servos are also used in in-line manufacturing, where high repetition yet precise work is necessary.

FAQs on Servo Motors

Q1. What is a servo motor used for?

A: Servo motors or “servos”, as they are known, are electronic devices and rotary or linear actuators that rotate and push parts of a machine with precision. Servos are mainly used on angular or linear positions and for specific velocity, and acceleration.

Q2. Why servo motors are best?

A: Servo motors are a better choice for systems requiring high speed, high acceleration, and high accuracy. The trade-off is a higher cost and complexity. Servo motors are typically used in packaging, converting, web processing, and similar applications.

Q3. Are servo motors AC or DC?

A: There are two types of servo motors, AC servos and DC servos. The main difference between the two motors is their source of power. AC servo motors rely on an electric outlet, rather than batteries like DC servo motors.

Q4. What is the working principle of a servo motor?

A: AC servo motors utilize alternating current for operation. They offer high torque-to-inertia ratios, making them ideal for applications requiring rapid acceleration and deceleration. The working principle involves controlling the amplitude and frequency of the AC input signal to achieve precise motor control.

Q5. Why is it called a servo motor?

A: The term "servo" refers to the control mechanism. In terms of technology, the mechanism that performs control is called the "master" and the mechanism being controlled is called the "slave." Both terms, "servo" and "slave" derive from "servus", the Latin word for slave.

Q6. What is the main function of the servo motor?

A: The function of the servo motor is to convert the control signal of the controller into the rotational angular displacement or angular velocity of the motor output shaft. Servo motor is used to drive the joints.
