Description
85 kg·cm micro remote control servo has a high-precision brushless motor, engineered for superior performance and durability. Digital radio control (RC) steering servos are widely used in various remote-controlled systems, such as model airplanes, cars, boats, and robots.
Features
- High resolution: Micro RC servo motor uses a non-contact absolute 12-bit encoder (360 degrees 0.088 degrees) with high resolution.
- Serial bus type: Radio control servo motor supports serial bus daisy chain, 254 ID addresses are optional.
- Position servo control mode: Digital remote control servo can rotate 0~360° and multiple turns of any absolute angle.
- Speed control mode: With a wide speed adjustment range, it can control continuous rotation in forward and reverse directions at a constant speed.
- One-button setting of intermediate position: The current position can be freely defined as the initial or intermediate point.

Tips: RC servo motor operation and performance characteristics
The digital radio control servo motor is widely used in automatic control occasions. Its output torque, rotation speed, command update frequency, etc. standardizes the working performance of the radio control servo motor. Normally, the operation of the micro remote control servo motor depends on the unique pulse command high-level time width and has nothing to do with the frequency of the pulse command. Therefore, the function of the pulse waveform that controls the RC servo motor and the PWM waveform that controls the operation of the motor are different. There is a drive circuit board inside the RC servo motor to ensure a proportional relationship between the output angle and the width of the pulse command. The output angular speed of the RC steering servo motor depends on various factors such as the internal mechanical structure, the performance of the motor, and the working voltage. Since the speed of the RC servo motor has nothing to do with the command, in essence, it is not a linear model. When it rotates at a larger angle, its dynamic nonlinearity is more obvious.
