Anmelden & bestellen →KST is a Chinese brand specializing in high-quality servos for RC models and robotics. The company produces brushless and digital series A, B, X, DS. The range includes models for aviation, cars, helicopters and drones. KST is known for its reliability and superior accuracy.
The microcontroller receives a PWM signal from the receiver. It determines the desired rotation angle. The brushless motor drives hardened steel gears. Two ball bearings ensure smooth running. The potentiometer monitors the actual position of the shaft. When there is a divergence, the controller turns the motor further. You get precise and powerful control.
Model A15-1812 operates at 6.0–8.4 VDC. Nominal voltage 7.4 V. Stopping torque 18 kg cm at 7.4 V. Nominal torque 5 kg cm. Stall current 2.85 A, rated current 0.92 A. No-load speed 0.12 seconds at 60 degrees.
Nominal speed 0.18 seconds. Operating frequency 1520 µs / 333 Hz. Default rotation angle is ±50° (total 100°). Operating temperature range from -20 to +65°C. Soft start is programmed via PC. Aluminum alloy body. Hardened steel gears. Position sensor – potentiometer. Two ball bearings. Case dimensions 35.5×15×32.5 mm. Weight 42 g ±10%.
The servo is designed for heavy RC airplanes and drones. Ideal for high voltage steering wheels. The brushless design requires no maintenance. High torque holds large surfaces. Programmable soft start prevents jerking.
