Overview
The Kpower HB1200T is a brushless servo motor for large-scale drones, special aircraft, eVTOL drones and industrial equipment. Its 1200 kg·cm stall torque, magnetic encoder and CNC steel gears support demanding positioning tasks. Operating at 24–32 V, it offers PWM, TTL and RS-485 interfaces, a customizable 120° travel range and a 25T, Ø16 mm horn spline for mechanical integration.
Features
- Brushless motor with magnetic encoder position sensing.
- CNC steel gears, an aluminum-alloy case and six ball bearings (6BB).
- Splined output shaft and mounting flanges for mechanical installation.
- PWM, TTL and RS-485 interfaces.
- 120° travel angle range, customizable.
- Operating temperature range of −40 to 85 °C and IP42 protection rating.
