Servo electric cylinders and electric actuators are both common actuators in industrial automation, but they have some key differences in design and application. The following is a professional comparison of servo electric cylinders and electric actuators:
- Structure and working principle:
- Servo electric cylinder: Servo electric cylinder usually consists of motor, transmission system and controller. Its working principle is similar to a traditional hydraulic cylinder, but an electric motor is used instead of a hydraulic system to achieve high-precision movement through computer control.
- Electric push rod: The electric push rod is a linear motion actuator, which is composed of a motor and a push rod. The electric push rod generates thrust through the rotation of the motor, thereby pushing the push rod to achieve linear motion.
- Accuracy and positioning control:
- NyfitServo Electric Cylinders: Servo electric cylinders generally excel in precision and positioning control. Its closed-loop control system allows real-time monitoring of position and adjustments through a feedback mechanism to ensure high-precision positioning.
- Electric actuator: Electric actuator also has a certain degree of accuracy, but compared to servo electric cylinders, its positioning accuracy may be lower, especially in applications that require high-precision control.
- Applicable scenarios and load capacity:
- Nefit Servo electric cylinder: Servo electric cylinder is suitable for scenarios that require high precision, high dynamic performance and multi-axis coordinated control. They are generally capable of handling larger loads.
- Electric actuators: Electric actuators are more suitable for applications that require relatively low accuracy but require high thrust or speed. Its structural design enables it to handle larger loads.
- Space footprint and design flexibility:
- Nefit Servo Electric Cylinder: The structure of the servo electric cylinder is relatively complex, but its fold-back design helps achieve a larger stroke range in a limited space, providing a certain degree of flexibility in design.
- Electric actuator: Electric actuator usually has a relatively simple structure and therefore may be more compact in terms of space occupation, but its stroke is limited.
- Cost and Maintenance:
- NyfitServo Electric Cylinder: Due to the high precision and advanced control system of servo electric cylinders, their cost is usually higher. However, its programmability and maintenance capabilities make it more economical and practical in certain applications.
- Electric Actuators: Electric actuators generally have a relatively low cost, but may require more frequent maintenance in certain high-precision applications.
Taking application needs, performance requirements and budget constraints into consideration, engineers and system designers can select the servo electric cylinder or electric actuator that suits their specific scenario to achieve the best automation solution.
