What is a servo motor?

Servo Motor is an engine that controls the operation of mechanical components in a servo system. It is an indirect transmission device that assists the motor. Servo motors have very accurate control speed and position accuracy and can convert voltage signals into torque and rotational speed to drive control objects. Its working principle is similar to the feedback control system. When the control signal is sent to the control circuit of the servo motor, the control circuit will adjust the speed and position of the engine according to the feedback signal to accurately achieve the predetermined target.

The main features of servo motors include small electromechanical time constant, high linearity, starting voltage, etc., and can quickly respond to changes in input signals. In addition, servo motors also have the advantages of high precision, high efficiency, good stability, and easy maintenance. Servo motors can be divided into DC and AC depending on the type. Their main characteristics are that there is no rotation when the signal voltage is zero, and the rotation speed decreases at a constant speed as the torque increases.

Servo motors are widely used in automation control, robotics, CNC machining, industrial production lines, and other applications requiring precise angle, speed, and position control. They are used in conjunction with other control systems, sensors, and controllers to achieve more complex motion control and automation functions, thereby improving production efficiency, product quality, and operating costs.

How do servo motors work?

The working principle of the servo motor is based on a closed-loop control system, which achieves precise driving of mechanical components by receiving input signals and accurately controlling its output. Specifically, the working principle of the servo motor can be broken down into the following key steps:

First, the control system sends a command signal containing the desired position, velocity, or acceleration information. The command signal can be a voltage signal, a pulse signal, or other electronic signal.

Next, the servo motor driver receives this command signal and converts it into a current or voltage signal suitable for the motor’s operation. The driver is the core part of the servo motor control system. It is responsible for converting the command signal into one the motor can understand and execute.

Then, after receiving the current or voltage signal output by the driver, the motor starts to rotate or move according to the command signal’s requirements. Servo motors usually have high-precision encoders or sensors for real-time detection of the motor’s position and speed information.

During the motor’s movement, the encoder or sensor continuously feeds back the motor’s actual position, speed, and other information to the control system. The control system calculates the error signal by comparing the command signal and the feedback signal and adjusts the driver’s output according to the error signal to correct the motor’s motion state.

By constantly comparing the command signal and the feedback signal and adjusting the driver’s output, the control system can ensure that the servo motor moves accurately according to the command signal’s requirements. This closed-loop control method ensures that the servo motor has very high accuracy and stability and can meet various complex and precise control needs.

Key components in servo motors and their functions

A servo motor is a complex system containing several key components, each integral in ensuring the motor’s precise and efficient operation. Here is a brief introduction to these components and their respective roles:

1. Motor body: The motor body is the core component of the servo motor. It converts electrical energy into mechanical energy through the principle of electromagnetic induction. It consists of a motor rotor and a stator. The rotor generates a magnetic field through permanent magnets, and the stator generates a magnetic field through coils. When the two interact, the motor can rotate or produce linear motion.

2. Controller: The controller is the “brain” of the servo motor. It is responsible for receiving signals or instructions from the outside and calculating the control signals according to the preset control algorithm. These control signals are then sent to the motor driver for precise control of motor movement. The controller can precisely control position, speed, and torque, ensuring the motor can act accurately according to instructions.

3. Driver: The driver is the bridge connecting the controller and the motor body. It converts the controller’s control signals into current and voltage signals that the motor can understand. The driver is not only responsible for driving the motor to rotate but also adjusts the motor’s speed, steering, and output torque according to the control signal. Through the driver’s function, the motor can achieve smooth start, stop, speed regulation, and high-precision position control.

4. Feedback device: The feedback device is integral to the servo motor closed-loop control system. It usually consists of an encoder and corresponding circuits. The encoder can detect the motor’s position, speed, and steering information in real-time and feed this information back to the controller. The controller adjusts the motor movement in real-time based on the comparison between the feedback signal and the command signal to ensure the motor movement’s accuracy. The feedback device gives the servo motor higher control accuracy and stability.

Installation of servo motor

1. Install the motor base: Install the motor base in a fixed place to ensure that the base is firmly installed to avoid shaking during operation.

2. Install the servo motor: correctly install the servo motor on the motor base according to the instructions.

3. Install the servo motor driver: Make sure that the connecting cable plug between the driver and the motor is tight and not loose.

4. Connect the power cord: When connecting the power cord, be careful not to connect it directly to the industrial power supply to prevent damage to the motor. At the same time, it is necessary to ensure the stability of the power supply and avoid the impact of voltage fluctuations on the motor.

5. Connect the control lines: Connect the control lines correctly according to the requirements of the control system.

6. Debugging: Follow the debugging steps in the manual to debug the servo motor to ensure it operates normally.

During the installation process, you also need to pay attention to the following points:

If the servo motor is connected to a reducer, an oil seal should be used to prevent oil from the reducer from entering the servo motor.

The bend radius of the cable should be as large as possible to avoid placing excessive tension on the cable.

When installing/removing the coupling component to the servo motor shaft end, do not directly hit the shaft end with a hammer to avoid damaging the encoder.

Ensure that the radial and axial loads on the servo motor shaft are controlled within specified values.

Maintenance of servo motor

1. Cleaning and dust prevention: Clean the servo motor driver regularly and keep the surface of the casing and radiator clean. Use methods such as a soft brush or air pressure blowing to remove accumulated dust and debris.
