The YMIN capacitor series, including polymer tantalum capacitors, film capacitors, aluminum electrolytic capacitors, supercapacitors, and ceramic capacitors, offers miniaturized custom products for robotic applications. These capacitors provide high-voltage filtering and peak assistance functions, crucial for enhancing the performance and efficiency of robotic systems.
Capacitors have extensive applications in robotics and industrial robots, playing crucial roles in several areas:
- Energy Storage and Release: Capacitors can store electrical energy and release it rapidly when needed. This is particularly useful for robots performing tasks that require high energy, such as motor startup, which demands a large current instantaneously. Capacitors provide the necessary high-power output, helping robots start and operate smoothly.
- Filtering and Power Supply Stabilization: In a robot's control system, capacitors are used for filtering to eliminate noise and spikes from the power supply, ensuring stability. This is critical for sensitive electronic components and sensors, ensuring accurate signal reception and processing.
- Energy Recovery Systems: In some industrial robots, especially those that frequently brake and accelerate, capacitors are used for energy recovery. The energy generated during braking can be temporarily stored in capacitors and released when needed, improving energy efficiency and reducing wastage.
- Pulse Power Supply: Capacitors can provide high-current pulse power in a short period, which is essential for specific tasks like welding and laser cutting robots. These tasks require high-energy bursts, and capacitors effectively meet this demand.
- Motor Drive and Control: Capacitors are used in motor drives to smooth motor operation, reducing fluctuations during startup and operation, thereby increasing motor efficiency and lifespan. In variable frequency drives, capacitors are used for DC link filtering, ensuring stable motor operation.
- Emergency Power Supply: In critical mission robots, such as medical and rescue robots, capacitors can serve as part of the emergency power supply. In the event of a main power failure, capacitors can provide short-term power, ensuring the robot can complete emergency tasks or shut down safely.
Through these applications, capacitors play an essential role in enhancing the performance and reliability of robotic and industrial robotic systems.

Capacitors play a crucial role in the development of contemporary robotics in several specific ways:
- Improving Energy Efficiency: Capacitors can store excess energy in energy recovery systems, such as the energy generated during braking processes in robots. This stored energy can be reused when needed, enhancing overall energy efficiency and reducing waste.
- Enhancing Power Stability: Capacitors are used to filter and stabilize power supplies, reducing voltage fluctuations and noise. This is essential for modern robots, particularly those that rely on precise electronic control and sensors. Stable power supply ensures the reliability and accuracy of robotic systems.
- Supporting High Energy Demand Tasks: Modern robots need to perform many high-energy tasks, such as high-speed movement, heavy load handling, and complex operations. Capacitors can provide high-energy output in a short time, meeting the instantaneous power demands of these tasks and improving the robots' performance and efficiency.
- Improving Motor Performance: In robots, motor drivers rely on capacitors to smooth the motor's startup and operation. Capacitors help reduce fluctuations during motor startup and operation, increasing motor efficiency and lifespan. Especially in variable frequency drives, capacitors play a crucial role in DC link filtering, ensuring stable motor operation.
- Increasing System Response Speed: Since capacitors can charge and discharge quickly, they can be used as temporary power reserves in robotic systems, ensuring rapid response when instantaneous power demands increase. This is vital for robotic applications requiring quick reactions and precise control, such as industrial automation and medical surgery robots.
- Enhancing Emergency Power Management: In critical missions and emergency situations, capacitors can serve as part of the emergency power supply. In case of main power failure, capacitors can provide short-term power, ensuring that robots can complete emergency tasks or shut down safely, enhancing system safety and reliability.
- Supporting Wireless Transmission and Miniaturization: As robots advance towards wireless and miniaturized designs, capacitors play a vital role in wireless energy transmission and micro-circuit design. They can store and release energy, supporting the efficient operation of wireless sensors and small actuators, promoting the diversification and flexibility of robot design.
Through these means, capacitors significantly enhance the efficiency, performance, reliability, and safety of robotic systems, driving the advancement of contemporary robotics technology.
