Drones are widely used in agriculture, logistics, security, aerial photography and other fields, and are constantly developing in a more efficient, intelligent and stable direction. As the core of drone power transmission, the motor drive system has increasingly higher performance requirements.
Capacitors play important roles in motor drive, such as filtering, voltage stabilization, and ripple suppression. Choosing the right capacitor can provide a solid power supply guarantee for the motor drive system of the drone. YMIN provides a variety of high-performance capacitor solutions for different application scenarios and technical requirements of drone motor drive systems – supercapacitors, polymer solid aluminum electrolytic capacitors, and polymer hybrid aluminum electrolytic capacitors, to help customers choose the most suitable capacitor solution according to actual needs.
Solution: Supercapacitors
When the drone motor starts, the current demand increases dramatically. The supercapacitor can provide high power output in a short time and respond quickly. The auxiliary battery helps the motor start smoothly, thus ensuring that the drone can take off quickly and run stably.
01 Low internal resistance
Supercapacitors can release electrical energy quickly in a short period of time and provide high power output. In the UAV motor drive system, the low internal resistance characteristic can effectively cope with the high current demand when the motor starts, reduce energy loss, and quickly provide the required starting current to ensure smooth motor start-up, avoid excessive battery discharge, and extend the service life of the system.
02 High capacity density
Supercapacitors have the characteristics of high capacity density, which can provide drones with high-power support for a longer period of time during flight, especially in the moments of rapid takeoff or when high power output is required, providing sufficient energy for the motor and improving flight stability and efficiency.
03 Wide temperature resistance
Supercapacitors can withstand a wide temperature range of -70℃~85℃. In extremely cold or hot weather, supercapacitors can still ensure the efficient startup and stable operation of the motor drive system, avoid performance degradation due to temperature changes, and ensure the reliability and stability of drones in various complex environments.

Solution: Polymer solid state & hybrid aluminum electrolytic capacitors
In the motor drive system, polymer solid aluminum electrolytic capacitors & polymer hybrid aluminum electrolytic capacitors can effectively stabilize the power output, smooth voltage fluctuations, and avoid the interference of current noise on the motor control system, thereby ensuring the precise control and stable operation of the motor under various workloads.
01 Miniaturization
In drones, volume and weight are very critical design parameters. Miniaturized capacitors can reduce space occupancy, reduce weight, optimize the overall system design, and provide stable power support for the motor, thereby improving flight performance and endurance.
02 Low internal resistance
In the drone motor drive system, there will be a short-term high current demand when the motor starts. Capacitors with low impedance characteristics can quickly provide current, reduce current loss, and ensure that the motor has sufficient power support when starting. This not only helps to improve the starting efficiency, but also effectively reduce the battery burden and extend battery life.
03 High quantization
During the flight of the drone, the motor will experience rapid load changes, and the power system needs to quickly provide stable current to maintain stable operation of the motor. Polymer solid aluminum electrolytic capacitors & polymer hybrid aluminum electrolytic capacitors can store a large amount of energy and quickly release electricity when there is a high load or high power demand, ensuring that the motor maintains efficient and stable operation throughout the flight, thereby improving flight time and performance.
04 High ripple current tolerance
UAV motor drive systems usually operate under high-frequency switching and high-power loads, which will cause large current ripples. Polymer solid aluminum electrolytic capacitors & polymer hybrid aluminum electrolytic capacitors have excellent large ripple current tolerance, can effectively filter out high-frequency noise and current ripples, stabilize voltage output, protect motor control systems from electromagnetic interference (EMI), and ensure precise control and stable operation of motors under high speed and complex loads.
