Overview
The Kpower DMC027 is a coreless digital servo for RC models, drones and compact actuation tasks. It combines titanium gears, a CNC-machined aluminum alloy mid-case and a 25T output spline. Specified torque is 2.8 kg·cm at 4.8 V and 3.6 kg·cm at 6.0 V, with corresponding speeds of 0.06 and 0.05 seconds per 60°, helping buyers match response and output to their mechanism.
Features
- Coreless cup motor with digital servo control.
- Semi-aluminum construction with a CNC-machined aluminum alloy mid-case.
- Precision-machined titanium gears and a 2BB bearing arrangement.
- 25T output spline for mechanical connection.
- PWM, TTL and RS485 are listed control interfaces.
- Custom wire lengths and OEM customization are available.

Applications
- RC aircraft, helicopters and drones: drive control linkages or landing-skid mechanisms using the coreless motor and the specified 0.06 s/60° response at 4.8 V or 0.05 s/60° at 6.0 V.
- RC cars and boats: actuate steering or other control linkages with a 25T output spline and titanium gear train.
- RC robots: position compact moving mechanisms with a 36 × 15 × 29 mm servo body and a 2 μs dead band.
- Smart-home and medical-equipment mechanisms: provide compact servo-driven positioning where the specified torque, response and physical size suit the mechanism.
