As the demand for industrial automation increases, industrial robots have been widely used in various production links and have become an important tool to improve automation levels and production efficiency. As the core component of industrial robots, servo motors adjust the position signal fed back by the encoder through the controller to accurately position and control the movement of each mechanical arm and motor, allowing the robot to complete tasks such as handling, assembly, and welding.
In order for the servo motor to maintain reliable operation under complex working conditions such as high precision, high speed and high load, its controller must have excellent stability, strong anti-interference performance and compact size. These requirements not only pose challenges to the design of the controller, but also set higher standards for the capacitors in it. As a key component inside the controller, the performance of the capacitor directly affects the response speed and operating accuracy of the servo motor.
YMIN provides polymer solid-state laminated capacitor solutions for the above high requirements. Its excellent performance effectively improves the performance and reliability of the servo motor controller and ensures the stable operation of the robot system under various harsh conditions.
01 Vibration resistant
The working environment of industrial robots is usually accompanied by strong vibrations, especially during high-precision movements. The laminated polymer solid aluminum electrolytic capacitor has strong anti-vibration ability, which can ensure stable operation under frequent mechanical vibration and is not prone to failure or performance degradation, thus improving the reliability and service life of the servo motor driver.
02 Miniaturization/thinness
Industrial robots often have high requirements on size and weight. The miniaturization and thin design of laminated polymer solid aluminum electrolytic capacitors provide stronger capacitive performance in limited space, help reduce the size and weight of motor drivers, and improve the space utilization efficiency and flexible movement of the overall system. It is particularly suitable for application scenarios with limited space.
03 Resistant to large ripple current
Industrial robot servo motor drivers need to work stably in high-frequency, large-current current ripple environments. Multilayer polymer solid aluminum electrolytic capacitors have excellent resistance to large ripple currents. The low ESR feature can effectively filter out high-frequency noise and ripples in the current, preventing power supply noise from affecting the precise control of the servo motor, thereby improving Drive power quality and motor control accuracy.
