Product Description
The HT7215 is a compact 24V hollow shaft brushless outrunner motor engineered for robotics, servo systems, industrial automation, rotary platforms, camera gimbals, and precision motion control applications. Designed with a high torque-to-size ratio, smooth operation, and low rotor inertia, it is an ideal solution for demanding closed-loop motion systems.
The encoder-free version features a large 35 mm through-hole, allowing convenient cable routing or limited slip-ring wire installation. Encoder-equipped versions integrate the encoder within the motor housing and are available with AS5600, AS5048A, or AS5047P magnetic encoders to satisfy different positioning accuracy requirements.
With its compact form factor, high dynamic response, and compatibility with modern FOC servo controllers, the HT7215 is suitable for robotic joints, pan-tilt mechanisms, rotary stages, AGVs, inspection equipment, and automation machinery requiring reliable brushless servo performance.

FAQ
What is the difference between the encoder and non-encoder versions?
The encoder-free version includes a 35 mm through-hole for cable routing. Encoder versions integrate a magnetic encoder inside the motor and do not include the full through-hole.
Which encoder options are available?
The HT7215 is available without an encoder or with AS5600, AS5048A, or AS5047P magnetic encoders.
Which encoder is recommended?
AS5600 is suitable for general positioning applications, while AS5048A and AS5047P are better choices for higher-precision closed-loop servo systems.
Can this motor be used in robot joints?
Yes. The HT7215 is designed for robotic joints, rotary actuators, servo mechanisms, and precision motion systems.
Does the motor support FOC control?
Yes. The HT7215 is designed for brushless servo applications and is compatible with appropriate FOC motor controllers.
What is the rated voltage?
The rated operating voltage is 24V DC.
Can the hollow shaft be used for cable routing?
Yes. The encoder-free version includes a 35 mm through-hole for routing cables or limited slip-ring wiring.
Is this suitable for rotary tables or pan-tilt systems?
Yes. The compact hollow shaft structure makes it well suited for rotary stages, pan-tilt mechanisms, and gimbal applications.
