Description
The HT4310 is a compact 24V hollow-shaft brushless gimbal motor designed for camera gimbals, optical payloads, stabilization platforms and precision rotary systems.
With a 49 mm outer diameter and 0.25 N·m nominal torque, the HT4310 provides higher torque than smaller compact gimbal motors while maintaining a low-profile pancake-style structure. It operates at a nominal speed of 250 RPM and supports speeds up to 690 RPM under no-load conditions.
The hollow-center design provides a convenient path for routing cables through the rotational axis, making the motor suitable for multi-axis gimbals, optical pods and robotic vision systems.
Optional AS5600, AS5048A and AS5047P magnetic encoder configurations are available for applications requiring rotor position feedback. Encoder versions are supplied with an encoder housing.
