Details
Brushless drive and high-precision metal gearing support compact, high-torque joints for robotics and embedded motion.
HBL090 sits in the HBL series line with multi-protocol control (PWM/TTL/RS-485) for flexible integration.
Match torque, speed, rotation angle, and operating voltage to the load profile before selecting a servo for a joint or actuator.
Multiple horn styles help fit different linkages and mounting patterns on robotic arms, grippers, and joint brackets.
Standard PWM positioning maps pulse width to angle, with compatibility guidance for higher-frequency control signals.
Customization support is available for appearance, torque, protocols, wiring sequences, and protection features when projects require it.
For continuous loads, use rated torque rather than stall torque as the practical sizing reference.
Standard 3-wire wiring keeps installation straightforward: brown (GND), red (Vcc), and orange (signal).
Key internal parts—gears, bearings, motor, and position sensor—work together to deliver repeatable, closed-loop motion.
Designed for a wide range of motion-control applications—from robot joints and automation to smart devices and UAV projects.
