The main functions and common applications of servo motors
1. A brief introduction to servo motors
A servo motor is an engine that controls the operation of mechanical elements in a servo system. It is an auxiliary motor indirect speed change device. A servo motor can convert voltage signals into torque and speed to drive the control object. Its core features are very high control speed and position accuracy. It can be used as an actuator in an automatic control system and has characteristics such as small electromechanical time constant and high linearity.
2. Structural components of servo motors
1. Stator: Made of laminated silicon steel sheets, with three-phase windings embedded to form a rotating magnetic field. The stator is the fixed part of the motor, usually called the excitation winding of the motor.
2. Rotor: Made of permanent magnetic material, it rotates with the rotating magnetic field. The rotor is the rotating part of the motor, usually called the armature winding.
3. Encoder: Used to detect the position and speed of the rotor, usually installed on the rotor shaft. The encoder has an approximate sensor that can determine the speed and revolutions per minute of the motor.
4. Driver: Receives instructions from the controller and converts them into drive signals to control the operation of the servo motor. The driver controls the speed and direction of the rotating magnetic field by controlling the current of the three-phase coil, thereby controlling the speed and direction of the servo motor.
3. The main functions of the servo motor
1. Accurately control the speed and position: The servo motor can accurately control the speed and position according to the change of the voltage signal to achieve uniform and stable movement. It is positioned by pulse signals. Every time a pulse current is received, it will rotate a corresponding angle, thereby achieving high-precision positioning with an accuracy of up to 0.001mm.
2. Convert voltage signals into torque and speed: The servo motor can convert the input voltage signal into torque and speed to drive the control object. This feature makes it an important actuator in the automation control system.
3. Fast response and high-precision feedback: The servo motor has the characteristics of fast response and can respond to the input signal in a short time. At the same time, it uses a closed-loop control system to feedback pulse signals in real time to ensure the accuracy of motion control.
4. Suitable for high-precision positioning scenarios: Servo motors are widely used in scenarios that require precise positioning, such as CNC machine tools, steering gears, etc. Its fast start-stop speed, small rotational inertia, large starting torque and rapid braking make it perform well in these fields.
5. Core role in servo system: The servo motor is a key component in the servo system, used to control the operation of mechanical elements. It achieves high-precision motion control by converting electrical signals into angular displacement or angular velocity output.
4. Common application industries of servo motors
1. Industrial automation: Servo motors are commonly used in CNC machine tools, printing equipment, packaging machinery and food processing equipment, etc., which can achieve high-precision and high-speed motion control and significantly improve production efficiency and product quality. In automated production lines, servo motors are used in robotic arms, conveyor belts, assembly machines, etc. to achieve precise position and speed control.
2. Robotics: Servo motors are key components of robot joint drives, which can convert electrical energy into mechanical energy, enabling robots to perform precise movements according to predetermined paths and motion modes.
3. Aerospace: Servo motors are used for attitude control and rudder drive of aircraft to ensure stable flight of aircraft in various environments.
4. Automotive manufacturing: Servo motors are used in engine management, brake systems, steering systems, etc. in automotive manufacturing to improve the performance and safety of automobiles.
5. Medical equipment: Servo motors are widely used in surgical robots, X-ray machines, CT scanners and other equipment to improve the accuracy and safety of medical operations.
6. Research equipment: Servo motors are used in scientific research for precision measurement, data analysis and other equipment to improve the accuracy and reliability of experiments.
7. Other industries: Servo motors are also used in medical examination equipment such as CT machines, B-ultrasound machines, and MRI machines to move patients; in the food packaging industry, such as the vacuum packaging production of snacks such as French fries; in the logistics and transportation industry, such as AGV vehicles in large storage warehouses for the transportation and allocation of goods; in microelectronics production and processing, such as chip production; and in cutting machines, such as water jet machines, which require servo motors to move the cutter head.
