LORDWORLD

LORDWORLD 20KG 7.4V 270° Waterproof Digital Servo Motor

SKU CH-HDYG-R9D8B

High-torque digital servo delivers 20 kg·cm at 7.4 V with 270° controllable rotation and full metal gears in an aluminium case

  • 20 kg·cm torque at 7.4 V powers heavy RC loads
  • Full metal gears improve accuracy and extend service life
  • Aluminium case enhances heat dissipation for stable operation
  • High-precision potentiometer delivers excellent linearity and precise control
  • 270° controllable rotation range with 360° free movement when unpowered

High-Torque Digital Servo

The LORDWORLD servo delivers 20 kg.cm of torque at 7.4 V, making it suitable for RC models and DIY robotics that demand strong, precise actuation. Its full metal gear train and aluminium housing improve durability and heat dissipation during sustained loads.

Voltage and Angle Compatibility

Verify that your power supply can provide a stable 7.4 V output before installation. Ensure the control system supports a 270° programmable range and that the mechanical linkage can accommodate the servo’s full rotation limits.

Build Integration

The aluminium case aids thermal management in compact chassis, while the high-precision potentiometer provides consistent position feedback. Free rotation through 360° when unpowered allows manual adjustment without disassembly.

Questions about this item

Does the LORDWORLD servo come with mounting hardware or do I need to buy horns and screws separately?

The supplier title and description list only the servo motor itself with full metal gears and an aluminium case. No horns, screws or mounting brackets are mentioned, so plan to source those separately for your RC or DIY build.

Should I choose the 7.4 V version or is there a different voltage option for this 20 kg·cm torque model?

The specifications give a single operating voltage of 7.4 V for the 20 kg·cm torque rating. No alternative voltage variants are described, so this is the only version available.

What does the 270 ° controllable angle mean when the servo is installed in my robot arm?

Powered, the servo can be commanded precisely from 0 ° to 270 ° with high linearity. When power is removed the output shaft moves freely through a full 360 ° range, allowing manual repositioning without back-driving the gear train.
