HP8-A45・Datasheet
1. Features
- Supports standard PWM control signals and is widely compatible with microcontrollers, servo controllers, and robot development platforms
- Equipped with a high-performance coreless motor for faster response and stronger torque output
- Built-in high-precision potentiometer position feedback enables smooth and stable closed-loop angle control
- Uses the industry-standard 25T output spline, compatible with common servo horns, metal arms, and structural accessories
- Built with a high-strength reinforced metal gear train that provides strong wear resistance and impact resistance
- Uses an aluminum CNC center case for better heat dissipation under high load
