PowerHD Servo WH-40KG – High-Voltage Digital Servo for RC Models
The PowerHD WH-40KG is a standard-size digital HV servo designed for RC models and robotics applications requiring high torque and fast response. It delivers 40 kg/cm of holding torque at 8.4V, making it suitable for demanding motion control tasks.
40 kg/cm holding torque at 8.4V provides strong, reliable actuation for heavy RC loads
Digital HV technology ensures precise positioning and fast 0.17s response time
Coreless motor design reduces friction and extends operational lifespan
Standard servo size (40.7 × 38.5 × 20.5 mm) fits most RC chassis and mounting setups
Unlike standard analog servos, the WH-40KG uses digital HV processing for significantly higher accuracy and speed. The coreless motor eliminates iron-core cogging, resulting in smoother motion and less wear over time.
Ideal für...
RC hobbyists building airplanes, helicopters, or ground vehicles that require a compact, high-torque servo. Also suited for robotics projects and automated models where precise angular control is critical.
Anwendung von PowerHD WH-40KG
Mount the servo in the designated compartment of your RC model, connect the signal and power leads to the receiver or controller, and secure the output shaft to the control surface or mechanism. Operate within the specified voltage range for optimal performance.
PowerHD manufactures standard-size digital servos for the RC and model-building market. The WH-40KG is positioned as a high-torque, high-voltage option within their servo range, targeting hobbyists and robotics builders who need reliable actuation in a compact form factor.
The WH-40KG is a standard-size digital HV servo used in RC models and robotics for precise, high-torque motion control of control surfaces, landing gear, and mechanical actuators.
The servo operates at 8.4V and delivers its rated 40 kg/cm holding torque at that voltage. Always use a compatible RC receiver or BEC that supplies 8.4V.
The servo measures 40.7 mm in length, 38.5 mm in height, and 20.5 mm in width, making it a standard-size servo that fits most RC chassis mounting positions.
The delivery includes one PowerHD WH-40KG digital HV servo. Mounting hardware and servo leads are not included unless specified in the product listing.
PowerHD provides a 24-month manufacturer warranty on the WH-40KG servo, covering manufacturing defects under normal operating conditions.
