Servo motor refers to the engine that controls the operation of mechanical components in the servo system. 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, high linearity, starting voltage, etc. It can convert the received electrical signal Converted into angular displacement or angular velocity output on the motor shaft. Divided into two categories: DC and AC servo motors.   Working principle A servo mechanism is an automatic control system that enables the output controlled quantities such as the position, orientation, and state of an object to follow any changes in the input target (or given value). The servo mainly relies on pulses for positioning. Basically, it can be understood that when the servo motor receives a pulse, it will rotate at an angle corresponding to the pulse, thereby achieving displacement. Because the servo motor itself has the function of emitting pulses, every time the servo motor rotates through an angle, it will emit a corresponding number of pulses. In this way, it forms a response to the pulses received by the servo motor, or is called a closed loop. In this way, the system will know How many pulses are sent to the servo motor and how many pulses are received back at the same time. In this way, the rotation of the motor can be controlled very accurately, thereby achieving precise positioning, which can reach 0.001mm. Classification of servo motors Servo motors can be divided into DC servo motors and AC servo motors. DC servo motor The basic structure of a DC servo is similar to that of a general DC motor. Motor speed n=E/K1j=(Ua-IaRa)/K1j, where E is the armature counter electromotive force, K is a constant, j is the magnetic flux of each pole, Ua and Ia are the armature voltage and armature current, Ra is The armature resistance, changing Ua or changing φ, can control the speed of the DC servo motor, but the method of controlling the armature voltage is generally used. In the permanent magnet DC servo motor, the excitation winding is replaced by a permanent magnet, and the magnetic flux φ is constant. . DC servo motor has good linear adjustment characteristics and fast time response. However, AC servo motors have limitations in brush commutation and speed, have additional resistance, and produce wear particles. AC servo motor The basic structure of an AC servo motor is similar to an AC induction motor (asynchronous motor). There are two excitation windings Wf and control windings WcoWf with a phase space displacement of 90° electrical angle on the stator. They are connected to a constant AC voltage and use the changes in the AC voltage or phase applied to Wc to control the operation of the motor. AC servo motors have the characteristics of stable operation, good controllability, fast response, high sensitivity, and strict nonlinearity indicators of mechanical characteristics and adjustment characteristics (required to be less than 10% to 15% and less than 15% to 25% respectively). Shungrui Motor, a subsidiary of Shunge, specializes in high-power and high-torque permanent magnet AC servo motors. It currently has two series, 18 and 25, which can meet the needs of most customers.

Control motors can be categorized into different types based on their functionality and application. The classification includes servo motors, stepper motors, torque motors, switched reluctance motors, and brushless DC motors. 1. Servo Motors Servo motors are extensively used in control systems for precise speed and position control. They convert input voltage signals into mechanical output, allowing controlled components to be manipulated. Servo motors are available in both DC and AC variants, with AC permanent magnet synchronous and DC brushless motors being commonly used. 2. Stepper Motors Stepper motors translate electrical pulses into angular displacement. By controlling the number of pulses, precise positioning, speed regulation, and acceleration can be achieved. Common types of stepper motors include reactive stepper motors, permanent magnet stepper motors, hybrid stepper motors, and single-phase stepper motors. 3. Torque Motors Torque motors are flat multi-pole permanent magnet DC motors designed to minimize torque and speed pulsations. They exhibit a good response and their output torque is proportional to the input current, regardless of rotor speed or position. Torque motors can operate at low speeds without the need for gear reduction, providing a high torque-to-inertia ratio. 4. Switched Reluctance Motors Switched reluctance motors feature a simple and robust structure, low cost, and excellent speed regulation performance. They are a competitive alternative to traditional control motors, although they may exhibit torque pulsation, noise, and vibration which require optimization and improvement for practical applications. 5. Brushless DC Motors Derived from brushed DC motors, brushless DC motors rely on AC drive current. They can be classified into brushless speed motors and brushless torque motors. The drive currents for brushless motors can be trapezoidal waves (commonly referred to as "square waves") or sine waves. Brushless DC motors are compact and lightweight compared to brushed DC motors, with reduced moment of inertia. Their capacities typically fall below 100kW. These classifications provide a comprehensive breakdown of control motors, each serving specific functions across various industries and applications.

After the industrial revolution, mechanical equipment was widely used in all walks of life. We usually see all kinds of large and small household appliances, but there is one thing that is important but not well known. It is——servo motor. industrial revolution Servo motor, or “servo” refers to the engine that controls the operation of mechanical components in the servo system. It is an indirect transmission device that assists the motor. Although servo motors are compact, they are very powerful and are known to be incredibly energy-efficient. Servo motors are used in home appliances, cars and industrial equipment. Servo motors can control speed and position accuracy very accurately, and can convert voltage signals into torque and rotational speed to drive control objects. 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, high linearity, starting voltage, etc. It can convert the received electrical signal Converted into angular displacement or angular velocity output on the motor shaft. They are divided into two categories: DC and AC servo motors. Their main feature is that there is no rotation when the signal voltage is zero, and the rotational speed decreases at a constant speed as the torque increases. All in all, servos can rotate and push parts of a machine with precision by its electronic devices and actuators, and is widely used by manufacturing companies. servo motor parts

Motors are designed to provide precise control over speed and direction, making them ideal for a wide range of applications. Using the suitable servo motor to develop an energy-saving solution for production, the power saving could reach at least 30%. A few factors are needed to take into consideration when it comes to customize your own servo motors: Servo Motor Nameplate 1. Determine the torque, power and speed requirements of your application. Determine the voltage and current requirements for the servo motor. Decide on the rotor type: Permanent magnet surface mount rotor or Permanent magnet embedded rotor. Choose a motor that can be supplied with the appropriate power source. This will help narrow down the selection of servo motors that are powerful enough to handle the workload. 2. Consider the environment or the using occasion such as equipment where the servo motor will be used. Operating temperature, humidity, and other environmental factors should be taken into consideration. Some motors are optimized for harsh industrial environments, while others are designed for more delicate laboratory settings. 3. Since protection level of servo motors is important, choose those with robust construction and high reliability. The motor's durability and performance are important factors to consider, especially if it is used in demanding applications that require it to operate continuously under heavy loads. 4. Decide on the cooling method: air cooling/ liquid cooling/ natural cooling. 5. Evaluate the control mechanisms and feedback systems of different servo motor options: Whether encoder is needed and which encoder type is appropriate? Whether matching driver of the servo motor is needed? resolver or other feedback device to control the position of the servo motor.Some motors have built-in motion control capabilities that can simplify system integration and improve performance. 6. Check the compatibility with the other components of your system. The servo motor you select must be compatible with the rest of your system, including the controller, power supply, and cabling.  7. Confirm on the size and weight: Consider the size and weight of the servo motor for your application. Choose a servo motor size that will fit within the available space. 8. Determine the cost of different servo motors and compare them against other factors such as performance, reliability, and compatibility. Remember that the cheapest option may not necessarily be the best option for your production needs.
