Overview
The Kpower DMC300 is a high-voltage coreless servo motor for remote-control cars, boats, fixed-wing aircraft and robotics. It operates at 4.8–8.4 V and combines wear-resistant metal gears with a plastic and aluminum-alloy case featuring an aluminum middle section. Its 120° travel is customizable, while potentiometer position sensing provides feedback. Listed control interfaces are PWM, TTL and RS-485.
Features
- Coreless motor with wear-resistant metal gears.
- Plastic and aluminum-alloy housing with an aluminum middle case.
- Potentiometer position sensor and two ball bearings.
- 120° travel angle, with customization supported.
- PWM, TTL and RS-485 listed as control interfaces.
