1. 85kg.Cmrs485 Metal Servo Motor, Metal Shell Brushless Motor, 360 Magnetic Encoding Servo Motor 2. Sturdy And Structural Design, All-Aluminum Alloy Shell + Cnc Precision Manufacturing, Improves The Heat Resistance, Dimensional Stability, Rigidity And Mechanical Performance Of The Servo Motor Shell 3. Brushless Motor, Steel Gearbox, Equipped With High-Quality Brushless Motor And Steel Gearbox To The Strength And Durability Of Servo Motor Power Transmission 4. High-Precision 360 Magnetic Encoder, Using 12-Bit High-Precision Magnetic Encoding Angle Sensor. Compared With Carbon Film Potentiometers, The Usable Angle Of Magnetic Encoders Is Expanded To 360, And The Resolution Is Increased By 4 Times. Since There Is A Space Between The Magnetic Encoder Elements And The Radial Magnet, There Is No Friction, Which Effectively Extends The Service Life Of The Servo Motor. 5. When The Voltage Reaches The Typical Voltage, The Locked-Rotor Torque Can Reach 85kg.Cm, Which Can Be Used To Build Four-Legged, Six-Legged, Robotic Arms And Other Robot Projects That Require Multiple Servo Motors, Easily Handling Large Robots.
