The motor drive system of drones has extremely high requirements for power response speed and stability, especially when taking off, accelerating or load mutations require instantaneous high power support.
YMIN capacitors have become the core components for optimizing motor performance with their characteristics such as resistance to large current impact, low internal resistance, and high capacity density, significantly improving the flight efficiency and reliability of drones.
1. Supercapacitors: Strong support for transient power
Low internal resistance and high power output: YMIN supercapacitors have extremely low internal resistance (can be lower than 6mΩ), which can release more than 20A of impact current at the moment of motor start-up, relieve battery load, and avoid power lag or battery over-discharge caused by current delay.
Wide temperature adaptability: Supports -70℃~85℃ working environment, ensuring smooth motor start-up of drones in extremely cold or high temperature environments, and preventing performance degradation caused by temperature fluctuations.
Extended battery life: High energy density design can store more electrical energy, assist in power supply when the motor is running at high load, reduce battery peak consumption, and increase battery life.
2. Polymer solid & hybrid capacitors: lightweight and high performance
Miniaturization and lightweight design: Ultra-thin packaging is used to reduce the weight of the motor control system and improve the thrust-to-weight ratio and maneuverability of the drone.
Ripple resistance and stability: The ability to withstand large ripple currents (ESR≤3mΩ) effectively filters out high-frequency noise, prevents the motor control signal from being interfered with by electromagnetic interference, and ensures precise speed control.
Long life guarantee: The life span is more than 2,000 hours at 105°C, and it can withstand 300,000 charge and discharge cycles, reducing maintenance frequency and adapting to long-term high-frequency operation scenarios.
3. Application effect: Comprehensive performance improvement
Starting efficiency optimization: Supercapacitors and batteries work together to respond to motor peak demand within 0.5 seconds and accelerate lift-off efficiency.
Enhanced system reliability: Polymer capacitors maintain voltage stability during frequent motor starts and stops, reduce damage to circuit components caused by current mutations, and extend motor life.
Environmental adaptability: The wide temperature characteristics support the stable flight of drones in areas with drastic temperature differences such as plateaus and deserts, expanding the operation scenarios.
Conclusion
YMIN capacitors solve the instantaneous power bottleneck and environmental adaptability problems in drone motor drives through the technical advantages of high response, impact resistance, and lightweight, providing key support for long-flight and high-load missions.
In the future, with the further improvement of capacitor energy density, YMIN is expected to promote the evolution of drones towards stronger power and intelligence.
