Introduction of Servo Motor

A servo motor is a rotary or translational motor driven by a servo amplifier to apply torque or force to a mechanical system such as an actuator or brake. Servo motors allow precise control of angular position, acceleration and velocity. This type of motor is associated with a closed loop control system. A closed-loop control system takes the current output into account and changes it to the desired condition. The control action in these systems is based on the output of the motor. It uses a positive feedback system to control the movement and final position of the axes.


There are two types of current in these motors - AC and DC. AC servo motors can handle higher current surges and are therefore more common in heavy industrial machinery. ISL's DC Servo Motors are best suited for small applications and provide excellent control and feedback. In a servo motor, the speed is determined by the frequency and number of poles of the applied voltage.


Servo motor (servo motor) refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect transmission device.


The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into the motor shaft. The angular displacement or angular velocity output. It is divided into two categories: DC and AC servo motors. Its main feature is that there is no self-rotation phenomenon when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque.

what is Industrial Servo Motors ?

A servo motor is an electromechanical device that produces torque and velocity based on the supplied current and voltage. A servo motor works as part of a closed loops system, which is comprised of a motor, feedback device, and servo drive providing important feedback on aspects such as position, velocity or torque.

Brief Description of Servo Motor

DC permanent magnet brushless synchronous servo motors can be widely used in machine tools, textiles, plastics, printing and dyeing, printing, building materials, packaging. woodworking, chemical industries and other fields.

The motor is composed of stator, rotor, high precision, feedback components (such as: incremental photoelectric encoder, resolver, etc.. The use of high-performance rare earth permanent magnetic materials to form the air gap magnetic field, and the use of inorganic shell stator cores, with large temperature gradients and high heat dissipation efficiency have the following characteristics:

●Compact structure, high power density:.Small moment of inertia, fast response.Ultra-high intrinsic coercivity rare earth permanent magnet material: strong resistance to demagnetization:
●Almost constant torque output in the entire speed range:
●Low-speed torque ripple is small: high balance accuracy, stable high-speed operation:
●Low noise, low vibration: fully sealed design, high cost performance.

Working of Servo Motor

A servo motor is an electrical device that converts electrical signals into mechanical motion. It is a closed-loop system that uses feedback to control the position or speed of a load. The basic working principle of a servo motor involves three main components: a control circuit, a motor, and a feedback mechanism.
The control circuit sends a signal to the motor, which rotates a shaft to a desired position. The feedback mechanism, usually a potentiometer or an encoder, measures the actual position of the shaft and sends the information back to the control circuit. The control circuit then adjusts the motor's rotation until the shaft reaches the desired position.
Servo motors are known for their accuracy, precision, and repeatability. They can operate at high speeds, and their torque can be controlled with great accuracy. These characteristics make servo motors ideal for use in robotics, manufacturing, and automation.
In summary, a servo motor works by receiving a signal from a control circuit, rotating a shaft to a desired position, and using feedback to ensure that the shaft is in the correct position.

Advantages of Servo Motor

Servo motors are increasingly being used in a wide range of industrial applications due to their numerous advantages over traditional motors. Here are some of the key advantages of servo motors:

High Precision: Servo motors offer extremely high precision, making them ideal for applications where accurate positioning and control is essential. They are capable of achieving very precise speed and torque control, which ensures the highest level of accuracy and repeatability.

High Efficiency: Servo motors are also highly efficient, with energy conversion rates of up to 90%, compared to the 50% efficiency of traditional motors. This means that they consume less energy and produce less heat, resulting in lower operating costs and longer lifespan.

Fast Response: Servo motors offer a very fast response time, enabling them to quickly adjust to changes in load or speed. This makes them ideal for applications where rapid changes in position or speed are required.

Wide Range of Motion: Servo motors can operate over a wide range of motion, from slow and steady movements to high-speed, dynamic movements. This versatility makes them suitable for a wide range of applications, from robotic automation to CNC machinery.

Low Maintenance: Servo motors require minimal maintenance due to their simple design and high reliability. This reduces downtime and maintenance costs, while improving overall productivity and efficiency.

Overall, the advantages of servo motors make them an excellent choice for a wide range of industrial applications, from precision manufacturing to heavy machinery.

What are Servo Motors Used For?

Servos are mostly used for industrial purposes. Important industries such as robotics, pharmaceutics, food services and in-line manufacturing also make use of servos. Servos are also most-suited for electrically operated pieces of machinery such as elevators, rudders, walking robots, and operating grippers.

Servo motors can also be used in many fields. According to the above advantages, we can also see that servo motors will be more used in industrial applications. Below, we will give examples of the advantages of servo motors in applications:
