What does the steering gear rely on to return to the neutral position?
Steering gear is a common electromechanical device that is widely used in robots, model aircraft, industrial automation and other fields. The return-to-neutral function of the servo is one of its core features, but many users do not know how to achieve the return-to-neutral position of the servo. This article will analyze in detail the principle of returning the servo to the neutral position, and provide readers with comprehensive answers based on hot topics and hot content in the past 10 days.
1. The principle of returning the steering gear to the neutral position
The steering gear's return-to-neutral function mainly relies on its internal feedback system and control circuit. The following are the key components of returning the servo to neutral position:
| components | Function |
|---|---|
| Potentiometer | Detect the current position of the servo and feed the signal back to the control circuit |
| control circuit | Compare the target position and the current position to drive the motor to rotate |
| Motor | Rotates according to the control signal to drive the output shaft |
| gear set | Slow down and transfer power, increase torque |
When the servo receives the instruction to return to the neutral position, the control circuit will set the target position to the intermediate value (usually a 1500 microsecond PWM signal), and then drive the motor to rotate until the current position detected by the potentiometer is consistent with the target position.
