Overview
The Kpower RC03T is a 9G-class micro coreless servo motor for compact positioning mechanisms in robots, robotic arms and equipment. Its 20.5 × 11 × 17.5 mm body combines copper gears with a 7075 aluminum case. Travel is 180° ± 5°, while stall torque at 5.0 V is 1.6 ± 0.20 kg·cm, helping buyers assess its suitability for small linkages and joints.
Features
- Coreless motor in a compact micro-servo format.
- Precision metal gearing made from copper.
- 7075 aluminum case.
- Pulse-control signal range of 500–2500 μs, with a 3 μs dead band and 50–333 Hz refresh frequency.
- Function customization support.
