Product Description
Structure and working principle of servo motor:
Servo motor is 1 of the commonly used motor,it is a motor that absolutely obeys the command of the control signal.Before the control signal is sent, the rotor is stationary;when the control signal is sent,the rotor rotates immediately;when the control signal disappears, the rotor can stop immediately.
As a special type of motor,synchronous servo motor is different from most other motors,it is designed for precise positioning,rather than speed controlling.

How are servo motors used in CNC machines and other precision machining equipment?
Servo motors play a crucial role in CNC (Computer Numerical Control) machines and other precision machining equipment. They provide precise and dynamic control over the movement of various axes, enabling high-accuracy positioning, rapid speed changes, and smooth motion profiles. Here’s a detailed explanation of how servo motors are used in CNC machines and precision machining equipment:
1. Axis Control:
CNC machines typically have multiple axes, such as X, Y, and Z for linear movements, as well as rotary axes for rotational movements. Servo motors are employed to drive each axis, converting electrical signals from the CNC controller into mechanical motion. The position, velocity, and acceleration of the servo motors are precisely controlled to achieve accurate and repeatable positioning of the machine’s tool or workpiece.
2. Feedback and Closed-Loop Control:
Servo motors in CNC machines are equipped with feedback devices, such as encoders or resolvers, to provide real-time information about the motor’s actual position. This feedback is used in a closed-loop control system, where the CNC controller continuously compares the desired position with the actual position and adjusts the motor’s control signals accordingly. This closed-loop control ensures accurate positioning and compensates for any errors, such as mechanical backlash or load variations.
3. Rapid and Precise Speed Changes:
Servo motors offer excellent dynamic response, allowing CNC machines to achieve rapid and precise speed changes during machining operations. By adjusting the control signals to the servo motors, the CNC controller can smoothly accelerate or decelerate the machine’s axes, resulting in efficient machining processes and reduced cycle times.
4. Contouring and Path Tracing:
CNC machines often perform complex machining tasks, such as contouring or following intricate paths. Servo motors enable precise path tracing by accurately controlling the position and velocity of the machine’s tool along the programmed path. This capability is crucial for producing intricate shapes, smooth curves, and intricate details with high precision.
5. Spindle Control:
In addition to axis control, servo motors are also used to control the spindle in CNC machines. The spindle motor, typically a servo motor, rotates the cutting tool or workpiece at the desired speed. Servo control ensures precise speed and torque control, allowing for optimal cutting conditions and surface finish quality.
6. Tool Changers and Automatic Tool Compensation:
CNC machines often feature automatic tool changers to switch between different cutting tools during machining operations. Servo motors are utilized to precisely position the tool changer mechanism, enabling quick and accurate tool changes. Additionally, servo motors can be used for automatic tool compensation, adjusting the tool’s position or orientation to compensate for wear, tool length variations, or tool offsets.
7. Synchronized Motion and Multi-Axis Coordination:
Servo motors enable synchronized motion and coordination between multiple axes in CNC machines. By precisely controlling the servo motors on different axes, complex machining operations involving simultaneous movements can be achieved. This capability is vital for tasks such as 3D contouring, thread cutting, and multi-axis machining.
In summary, servo motors are integral components of CNC machines and precision machining equipment. They provide accurate and dynamic control over the machine’s axes, enabling high-precision positioning, rapid speed changes, contouring, spindle control, tool changers, and multi-axis coordination. The combination of servo motor technology and CNC control systems allows for precise, efficient, and versatile machining operations in various industries.
What factors should be considered when selecting a servo motor for a specific application?
When selecting a servo motor for a specific application, several factors need to be considered. These factors help ensure that the chosen servo motor meets the requirements and performs optimally in the intended application. Here are some key factors to consider:
1. Torque and Power Requirements:
One of the primary considerations is the torque and power requirements of the application. The servo motor should be able to generate sufficient torque to handle the load and overcome any resistance or friction in the system. Additionally, the power rating of the motor should match the power supply available in the application. It is essential to evaluate the torque-speed characteristics of the servo motor to ensure it can deliver the required performance.
2. Speed and Acceleration:
The required speed and acceleration capabilities of the servo motor should align with the application’s needs. Different applications have varying speed and acceleration requirements, and the servo motor should be able to meet these demands. It is crucial to consider both the maximum speed that the motor can achieve and the time it takes to accelerate or decelerate to specific speeds. Evaluating the servo motor’s speed-torque characteristics and acceleration capabilities is necessary for selecting the right motor.
3. Positioning Accuracy and Repeatability:
The desired positioning accuracy and repeatability of the application play a significant role in servo motor selection. If precise positioning is crucial, a servo motor with high accuracy and low positioning errors should be chosen. The feedback mechanism, such as encoders or resolvers, should provide the required resolution to achieve the desired accuracy. Repeatability, the ability to consistently reach the same position, should also be considered, especially in applications where repetitive movements are necessary.
4. Environmental Conditions:
The environmental conditions in which the servo motor will operate should be taken into account. Factors such as temperature extremes, humidity, dust, and vibration can affect the motor’s performance and lifespan. In harsh environments, it may be necessary to choose a servo motor with appropriate protection ratings, such as IP (Ingress Protection) ratings, to ensure reliable operation and longevity.
5. Control System Compatibility:
The compatibility of the servo motor with the control system used in the application is crucial. The motor should be compatible with the control signals and communication protocols employed in the system. This includes considerations such as voltage compatibility, control signal types (analog, digital, pulse), and communication interfaces (such as Ethernet, CAN, or Modbus). Ensuring compatibility will facilitate seamless integration and efficient control of the servo motor within the application.
6. Size and Weight Constraints:
The physical size and weight limitations of the application should be considered when selecting a servo motor. The motor’s dimensions should fit within the available space, and its weight should not exceed the application’s weight capacity. Compact and lightweight servo motors may be preferred in applications where space is limited or weight is a critical factor.
7. Cost Considerations:
The cost of the servo motor and its overall value for the application should be evaluated. It is essential to consider the initial purchase cost as well as the long-term maintenance and operational costs. While cost is a factor, it should not be the sole determining factor, as compromising on quality or performance may lead to suboptimal results.
By considering these factors, one can make an informed decision when selecting a servo motor for a specific application. It is recommended to consult with manufacturers or experts in the field to ensure the chosen servo motor meets the application’s requirements and provides reliable and efficient performance.
