In a motor where precision and control are paramount, the servo motor takes center stage. But What is the servo motor working principle and application? This blog post will delve into the working principles of servo motors and explore their wide range of applications across industries from robotics to consumer electronics.
Servo Motor Principles
The working principle of the servo motor is mainly based on a closed-loop control system, which can accurately control the position, speed and torque of the motor.
When the servo system receives a control signal, the servo controller processes and analyzes the signal, and then sends the result to the servo motor. After the servo motor receives the signal, it converts the electrical signal into mechanical motion through the internal control algorithm and drive device.
At the same time, every time the servo motor rotates by an angle, it will send out a corresponding number of pulses, forming a closed-loop system.
The Servo Motor’s Key Components
Servo motors comprise three key components: the motor stator rotor, an encoder for feedback, and a controller. The motor is responsible for generating mechanical motion control, while the encoder provides data on the motor’s current position. The controller interprets this feedback and makes adjustments to maintain the desired state.
Types Of Servo-Electric Motors
Servo motors are mainly divided into two categories: DC motors and AC motors. Among them, DC servo motors can be divided into brushed and brushless motors. In addition, stepper servo motors and linear servo motors are also common servo motor types.

FAQS
How are servo motor laminations manufactured?
Servo motor laminations manufacturing through the use of a precision stamping process(such as compound stamping, progressive stamping, and rotary notching).
This involves feeding a continuous strip of electrical steel (often silicon steel) through a die set, where it is stamped and cut into laminations with precise shapes and dimensions. These laminations are then stacked and insulated to create the motor’s core.
