What is steering gear stroke
Steering gear stroke is a common concept in robots, aircraft models and automation equipment. It refers to the movement range of the output shaft from the minimum position to the maximum position after the steering gear receives a control signal. Understanding servo travel is critical to accurately controlling servo movement. This article will introduce in detail the definition and working principle of the servo stroke and how to adjust the servo stroke, and attach the hot topics and hot content in the past 10 days for reference.
1. Definition of steering gear stroke
The servo stroke is usually expressed in angle or pulse width. The common servo stroke range is 0° to 180°. The range of motion of the servo is determined by the control signal. The control signal is usually a PWM (pulse width modulation) signal, whose pulse width determines the position of the servo.
| parameters | Description |
|---|---|
| Minimum stroke | The minimum position of the servo output shaft, usually corresponding to the minimum pulse width of the PWM signal (such as 500μs) |
| Maximum stroke | The maximum position of the servo output shaft, usually corresponding to the maximum pulse width of the PWM signal (such as 2500μs) |
| neutral position | The middle position of the servo output shaft, usually corresponding to the neutral pulse width of the PWM signal (such as 1500μs) |
2. Working principle of steering gear stroke
The steering gear usually contains a motor, reduction gear set, position feedback potentiometer and control circuit. When the control signal is input, the control circuit drives the motor to rotate according to the pulse width until the voltage of the feedback potentiometer matches the target position.
The travel range of the servo is preset by the manufacturer, but some servos allow the user to change the travel by adjusting the pulse width range of the control signal. For example, some servos can be programmed or physically adjusted to extend or limit their range of travel.
3. How to adjust the steering gear stroke
Adjusting the servo stroke usually requires the following steps:
| steps | Operation |
|---|---|
| 1. Determine the type of steering gear | Check whether the servo supports stroke adjustment. This can usually be confirmed through the manual or the manufacturer's website. |
| 2. Connect the controller | Connect the servo to the controller (such as Arduino, servo tester) |
| 3. Send test signal | Send the minimum and maximum pulse width signals to observe the servo movement range |
| 4. Adjust signal range | Adjust the pulse width range of the control signal as needed to change the stroke |
