High Precision 360° Magnetic Encoder

Adopts 12-bit high-precision magnetic encoding angle sensor. Compared with the carbon film potentiometer, the angle of the magnetic encoder is enlarged to 360°, and the resolution is increased by 4 times. Since there is a gap and no friction between the magnetic encoder and the radial magnet, the motor lifetime is effectively extended.

RSBL85-12 / RSBL85-24 Servo Motor, with high precision 360° magnetic encoder
Small size, Large Torque

Up To 85kg.Cm Torque On typical Voltage, Suitable For Building Quadruped Robots, Hexapod Walkers, Robotic Arms And Other Robotic Projects Requiring Multiple motors

RSBL85-12 / RSBL85-24 Servo Motor, with large torque, suitable for Robotic arms

Note: the robot arm in the picture above is not included, but we provide its open-source drawing on the wiki. Please refer to the Package Content for detailed part list

UART Serial Bus Control

Up to 253 servo motors controlling at the same time, with simple wiring, reducing the occupation of the serial port

RSBL85-12 / RSBL85-24 Servo Motor, with large torque, up to 253 servo motors controlling

Note: though one channel UART can control up to 253 servo motors, due to the high power of the motors, it is necessary to consider whether the power supply solution is enough when using too many motors.

Acceleration Start-stop Function

The speed and acceleration values are settable to make the motion effect softer and reduce impact from inertia


One Button to Calibrate the Middle Position

360° installation at any position, one button to set the current position as middle position. Easy to install and debug

Click Release to unlock, then turn the servo motor to the middle position where you want to set

Click Set Middle Position then confirm.

Turn the servo motor to any angle, then click Middle, and the servo motor will automatically return to the middle position initially set.

Closed-loop feedback with real-time protection

The servo motor Will Provide Various Feedback Like Position, Load, Speed, Input Voltage, Current and Temperature In Real Time, with unloading force protection when the servo motor is overheated or overloaded

RSBL85-12 / RSBL85-24 Servo Motor, supports closed-loop feedback with real-time protection
Multiple operation modes
suitable for more application scenarios

Angle servo mode
Default mode, the angle position is controllable at 0~360° degrees

Speed closed-loop mode
Intelligently control and maintain speed when the load changes

Step mode
Can perform step motion relative to the current position

Multi-Loop angle Position control

Supports angle position control in both positive and negative directions up to 7 loops under the default precision setting, but the number of loops will not be saved in case of power loss. Lowering the angle resolution can double the number of control loops
