Overview
The Kpower DHV822 is a high-speed servo motor for controlled angular positioning in robotic mechanisms. Its coreless motor, steel gears and CNC aluminium case combine with a compact 40 × 20 × 39 mm body. Listed PWM, TTL and RS-485 protocols provide control-interface selection criteria, while voltage-specific speed, torque and current figures help assess power and motion requirements.
Features
- DHV822 high-speed servo with a coreless motor.
- Steel gears and a CNC-machined 7075 aluminium case.
- Listed control protocols: PWM, TTL and RS-485.
- 120° ± 3° travel angle, 3 μs dead band and 50–333 Hz refresh frequency.

Applications
- Robotic linkage positioning: Use the 120° ± 3° travel range for bounded angular movement in a linkage or small joint mechanism.
- Repeated angular actuation: The high-speed coreless servo supports mechanisms requiring repeated position changes; use the voltage-specific no-load speed and current figures when planning motion and power requirements.
