A servomechanism, usually shortened to just servo, is a device used to provide mechanical control at a distance. For example, a servo can be used at a remote location to proportionally follow the angular position of a control knob. The connection between the two is not mechanical, but electrical or wireless, for example.
The most common type of servo is that mentioned, which gives positional control. Servos are commonly electrical or partially electronic in nature, using an electric motor as the primary means of creating mechanical force, though other types that use hydraulics, pneumatics or magnetic principles are available. Usually, servos operate on the principle of negative feedback, where the control input is compared to the actual position of the mechanical system as measured by some sort of transducer at the output. Any difference between the actual and wanted values (an "error signal") is amplified and used to drive the system in the direction necessary to reduce or eliminate the error. A whole science of this type of system has been developed, known as control theory.
Servos are found in many applications. They operate the throttle of engines that use a cruise control. CNC machines use servos to make the motion axes of a machine tool follow the desired tool path. Fly-by-wire systems in aircraft use servos to actuate the control surfaces that control the aircraft. Radio-controlled airplanes use servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the focus.
I believe that servo is motorized and solenoid is magnetically activated.
A brake servo is a servo that is used for brakes That's all folks
The main function of a valve actuator is to control the valves ON to Close or modulating the valve,and the motor operated valve actuator is one important kind of valve actuator,the main different between kind valve actuators is it drive by electric power.
A servo mechanism is one where there is a control system, and actuator; and where there is feedback from the actuator to provide agreement with the control signal. The cruise control on your car is a servo system, for it senses the actuator's effect (road speed) and sends back a signal to the accelerator to adjust the car speed to the set target. Early servo mechanisms (but not the earliest) used an electrical motor, which was also able to send back information on its position. This feedback is the essential part of a servo mechanism. Probably the origin of the word is allied to "servant".
A stabilizing servo. To quote Blitzwing:Careful you clobber clad klutz! You stepped in something! But with a few dancing lessons you'll be light on your stabilizing servo's like me!
What is the difference between servo valves and proportional valvesThere are no strict rules between Servo valves and proportional valves, because the proportional valve"s performance is getting better, gradually close to the servo valve, so in recent years there has been proportional servo valve. The difference between servo and proportional valve can be divided into the following points: 1. Drive different.2. Different performance parameters.3. Different valve structure and precision.4. Function in different types.5. Valve rated pressure drop are different.So people can choose the different kinds of valves on the basic of you require.Angad kumar pandey

it is a regulator of servoing and pressure control to oversee the valve
A Servo Valves is a device that meters the flow of oil in response to an electrical input signal or command to control position, velocity, pressure or force in some type of machine or device (usually through a piston or cylinder).
They are either servo type or non servo type, they can't be both types.
A micro servo is a small servo. The term can be used to describe any servo that is smaller than a "typical" servo. For example a servo that is about 1.5" x 1.5" x 0.5" would probably be called a micro servo. Most servos use the same signals and voltages, so usually a micro servo can be plugged into any servo controller or radio receiver that a regular servo can be plugged into.
A brake servo is a servo that is used for brakes That's all folks
Piero Servo's birth name is Servo, Giampiero.
Servo in Finnish is a loan-word from the English word servomechanism or servo.
why are air brakes considered non-servo
Servo brakes x2
The servo motor is a type of motor which acts according to the command of the user. which serves the purpose of the user. therefore it is called as "servo" motor
