Buy KST X08H V6.0 Programmable Micro Servo Drive for your FPV Drone and Miniature Gears!
Ensure precise control of actuators under severe weight constraints. The KST X08H V6.0 servo is designed for high performance models such as DLG and F3K gliders, but is also ideal for controlling light weight drop systems and micro gimbals on FPV drones .
With an ultra-thin housing of just 8 mm thick and a weight of 8 grams, this servo easily integrates into the most compact designs . A wide operating voltage range from 3.8V to 8.4V and programmable Soft Start make it an ideal choice for projects where every detail matters.
-
Premium Coreless motor. Highly efficient coreless motor with improved magnetic properties (N45H) ensures fast response and minimal energy loss .
-
High torque. Develops force up to 2.8 kg/cm at a voltage of 8.4V for confident control of mechanisms.
-
Lightning speed. Just 0.09 seconds per 60 degrees at 8.4V guarantees perfect response to pilot commands.
-
Maximum reliability. Hardened steel gears and dual ball bearings ensure durability and minimal play .
-
Programmable functions. Supports parameter settings, including the Soft Start function, via KST-Tool #3 and #5.
Operating principle and design
KST X08H V6.0 is a digital HV micro servo drive based on advanced coreless motor technology. Unlike traditional iron-core motors, a coreless motor has significantly lower rotor inertia, allowing it to accelerate and decelerate almost instantly, providing exceptional positioning accuracy . Digital technology guarantees higher angular resolution and faster and more accurate position holding compared to analogue servos .
The durable aluminum alloy body, precision machined, not only adds rigidity to the structure, but also effectively dissipates heat from the motor and electronics . Five-pole rotor with N45H magnets provides increased magnetic flux density and reduces winding inductance to avoid speed saturation at high voltage . The hardened steel gearbox with two precision ball bearings minimizes backlash and guarantees durability even under heavy-duty conditions.
