Servo motor: what is the continuous servo motor?

In summary, the conversation discusses two types of servo motors - continuous and non-continuous. The continuous servo can rotate to any angular position between 0 and 360 degrees, while the non-continuous servo has a limited range of rotation (0 to 180 degrees). The use of endpoints on a transmitter can prevent the servo from reaching undesired angles. The question is raised about using a comparator or difference amplifier to operate the servo based on varying levels of light detected by two sensors.

Hello Forum,

there are two typeos of servo motors. One of them is called continuous. does it mean that it can rotate to any angular position, between 0 degrees and 360?

The other type (the non continuous one) still rotates at any angular position, but only within a limited range, like 0 to 180 degrees...

Is that correct?

thanks,

Sounds correct.
I have been flying RC helis for a few years and have messed around with servos and have never come across either of these terms. How strange.
We use endpoints to stop our servos reaching undesired angles, this is done on a transmitter (TX). I guess you could say this is enough for it to qualify as a non-continuous servo.

cool, thanks.

I need to have the servo move based on the different amount of light falling on two detectors...
would you use a comparator or a difference amplifier to operate the servo?

for the difference amplifier the voltage output is proportional to the voltage difference between the two inputs.

thanks,

1. What is a continuous servo motor?

A continuous servo motor is a type of motor that can rotate continuously in either direction, unlike a standard servo motor that is limited to a specific range of motion. It is commonly used in robotics, automation, and other applications where precise and continuous rotation is required.

2. How does a continuous servo motor work?

A continuous servo motor works by using a control signal to adjust the speed and direction of the motor's rotation. This control signal is usually a pulse-width modulation (PWM) signal, which varies the voltage and frequency to control the motor's speed and direction.

3. What are the differences between a continuous servo motor and a standard servo motor?

A standard servo motor is designed with gears and a limited range of motion, while a continuous servo motor has no gears and can rotate continuously. Additionally, a standard servo motor has a position feedback mechanism, while a continuous servo motor does not.

4. What are the applications of a continuous servo motor?

Continuous servo motors are commonly used in robotics, automation, and other applications where precise and continuous rotation is required. They are also used in camera gimbals, RC vehicles, and other hobby projects.

5. How do I control a continuous servo motor?

To control a continuous servo motor, you will need a microcontroller or a motor controller that can generate a PWM signal. The PWM signal will vary the voltage and frequency to control the motor's speed and direction. You can also use a potentiometer or other sensors to provide analog control of the motor.
