Overview
The Kpower DMC090 is a coreless digital servo for RC steering, helicopter control and other positioning tasks. Its titanium gears, aluminum-alloy mid case and 25T output spline provide key construction and fit details for selecting a servo. Torque is specified at 7.9 kg·cm at 4.8 V and 8.8 kg·cm at 6.0 V, with corresponding speeds of 0.12 and 0.11 seconds per 60°.
Features
- Coreless cup motor with digital servo control.
- Semi-aluminum construction with a CNC-machined aluminum-alloy mid case.
- Precision-machined metal gears, specified as titanium.
- 2BB bearing arrangement and 25T output spline.
- PWM, TTL and RS485 control compatibility.
- Three-wire lead with a three-position connector.
- Waterproof construction.
