Overview

The Kpower HB300T is a brushless servo motor for large-drone mechanisms, robotic actuation and industrial automation. It delivers 300 kg·cm stall torque and a no-load speed of 0.18 s/60° at 24 V. Steel gears and magnetic-encoder position sensing support controlled movement, while the 64 × 33 × 92.3 mm housing helps define installation space. Its operating voltage range is 24–32 V.

Features

  • Brushless motor with steel gears and magnetic-encoder position feedback.
  • Aluminum-alloy case with six ball bearings (6BB).
  • Splined output shaft with a central threaded opening and mounting flanges with fastening holes.
  • 25T output spline with an 11.8 mm diameter.
  • PWM, TTL and RS-485 interfaces.
  • 120° travel angle, with customization indicated for the travel range.
