Waveshare 20kg.Cm Bus Servo Motor, 106PRM High Speed, Large Torque, with 360 Degrees High Precision Magnetic Encoder, Two-Way Feedback, Servo/Motor Mode Switchable - ST3215-HS Servo Motor

• Servo motor will provide various feedback like position, speed, torque lock, working mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control. Ideal choice for building wheeled robots, 3D printers, etc. that require accurate closed-loop speed control or stepping control. it can also be used for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servo motors. (This product provides the open source model of the quadruped robots as shown in the picture below.) Up To 20kg.Cm Torque On 12V Voltage, Suitable For Building Quadruped Robots,Hexapod Walkers, Robotic Arms And Other Robotic Projects Requiring Multiple Servo. Motors With Large Torque And High Speed Performance. Allows Controlling Up To 253 Bus Servo Motors At The Same Time With The Flat Key Shaft Flange Designed For The Serial Bus Servo, It Is Possible. To Drive Various Transmission Parts Adopts 12-bit high-precision magnetic encoding angle sensor. Compared with the potentiometer, the angle 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 lifetime of the motor is effectively extended.
