Buy an original KST HA20-9015 servo for your FPV drone!
Provide precise and reliable control of your drone's actuators. The KST HA20-9015 servo drive is designed for the most demanding applications, including control of camera gimbals, load release mechanisms and other systems where accuracy and speed are important. The device is characterized by high build quality and the use of premium components, which guarantees a long service life even under intensive use. Compact dimensions and low weight allow the servo drive to be easily integrated into designs of any size.
-
High torque. Develops force up to 2.9 kg/cm at a voltage of 7.4V for confident control of mechanisms.
-
Lightning speed. Travel time is just 0.08 seconds per 60 degrees at 7.4V for instant response.
-
Metal gears. The robust, hardened steel gearbox ensures durability and shock resistance.
-
Double ball bearings. Provide smooth running and minimal play of the output shaft.
-
High voltage (HV) support. Operates directly from 2S LiPo (up to 8.4V) without additional stabilizers.
Operating principle and design
The KST HA20-9015 servo drive belongs to a class of digital microservos designed for precise positioning in confined spaces. It is powered by a high-speed microprocessor that processes signals from the receiver or flight controller at high frequencies, ensuring exceptional precision and smooth movements. Digital technology guarantees quick retention of a given position without jerking or overshoot.
The robust metal gearbox ensures resistance to the shock loads that are inevitable during hard landings of drones. Two precision ball bearings on the output shaft minimize backlash, ensuring positioning accuracy even after long periods of use. The compact aluminum housing effectively dissipates heat, maintaining stable performance over long periods of operation.
