Where does the word "servo" come from in engineering?

Modern servomechanisms employ solid-state power amplifiers, which are often constructed from MOSFET or thyristor transistors. Power transistors may be used in small servos. The term is said to have originated from the French "Le Servomoteur," or slavemotor, which was originally used by J. J. L. Farcot in 1868 to describe hydraulic and steam engines used in ship steering.

Where are servo motors found?

Servo motors (or servos) are self-contained electric devices that spin or push machine elements with high accuracy (see Figure 1 below). Servos may be used in a variety of applications, ranging from toys to home electronics to automobiles and airplanes. They are commonly used as positioning actuators in robotics.

Why do we need servos?

Servos provide rotational movement with very little friction or vibration, which makes them ideal for applications where these properties are important. They can also operate at very low speeds for their size, which is useful when you need precise movement but don't have time to go fast. Finally, they are extremely accurate - even down to 0.01 degrees - which means they can be used without risk of collision in applications such as air traffic control.

What types of servos exist?

There are two main types of servos: gear-type and linear-induction-motor (LIMO)-type. Gear-type servos use a set of gears to step up or down the speed of the motor, while LIMOs directly drive the shaft using magnetic forces. Both types can run on either AC or DC power.

What is the definition of "servo"?

A servo (servomechanism) is an electromagnetic device that uses negative feedback mechanisms to transform power into precise, controlled motion. Depending on the kind, servos can provide either linear or circular motion. Servos are used in radio-controlled cars, aircraft, and weapons systems; in industrial robots; and in some types of medical equipment.

The word "servo" comes from the Latin word servus, meaning "slave." This reflects its original use as a control mechanism for machinery which was operated by a human slave.

Modern servos have replaced mechanical levers and valves as sensors and actuators for robotic applications. They can be found in radio-controlled cars, aircraft, and weapons systems; in industrial robots; and in some types of medical equipment.

The servo unit provides speed control for the motor by applying voltage to the armature winding at a rate that keeps the rotor spinning, regardless of the position of the control knob. This is in contrast to a conventional motor, which will run fast or slow depending on how far you turn it. A low gear ratio on a conventional motor allows it to be driven by a small battery, but it will still need a large motor to do any good.

What is the servo motor's simple definition?

A servomotor is a rotary or linear actuator that enables precise control of angular or linear position, velocity, and acceleration. It comprises of a suitable motor connected to a position feedback sensor. Servomotors are utilized in a variety of applications, including robotics, CNC machines, and automated manufacturing. They can also be found as part of larger industrial automation systems.

The servo motor was invented by Fritz Koenig in Germany in 1919. He called it a "position controller" because it could maintain a fixed position despite external forces such as friction or unbalanced weights. The first mass-produced servo motor was sold under the name "Radiodrome" by the Radio Corporation of America (RCA) in 1949.

Servo motors are available in a wide range of sizes and speeds. They can drive mechanical elements such as valves or pumps, or they can operate electrical machinery such as solenoids or motors. Some servo motors are internal to instruments such as oscilloscopes and transmit signals through their shaft. Others are attached to equipment housing structures that provide visual feedback through positioning movements.

A servo system consists of a servo motor and an associated controller. The controller receives position commands from a source such as a microcontroller or computer terminal and sends appropriate current signals to the motor to achieve this position. The controller may include additional functions such as speed regulation, power management, or fault detection.

What is a micro servo?

The servomotor is used in many applications including machine tools, industrial robots, air traffic control devices, and spacecraft instruments.

The word "servo" comes from the Latin word servus, which means "slave." Thus, a servo mechanism controls another device by controlling its own movement. This type of mechanism is called a closed-loop system because it has an action (output) that depends on the current status of the mechanism (input). For example, if the position of a knob on a radio is turned counterclockwise, the knob will act as a signal for the radio to play music; if turned clockwise, the radio will switch to the next station. The mechanism that turns the knob is a servo mechanism.

A servo motor is a motor with a built-in controller that uses magnetic forces to rotate a shaft. This allows the servo motor to move objects precisely without getting stuck due to friction. A standard DC servo motor uses magnetic forces on a rotor within the motor to rotate a shaft. The shaft is attached to whatever needs to be moved.

What does "servo" mean in Australia?

Meaning of servo A service station is a location where you may purchase gasoline. These facilities are usually found at interstate highways and large city streets. Today, they are also found at airports and military bases.

Origin: American English, 1930s-40s

Servo motor was invented by Elmer Sperry in 1930. It was first used in his watch. Later on, it became popular as a self-winding movement for wrist watches.

Elmer Sperry was an American engineer who invented the first mass-manufactured automatic pilot in 1930. The device used radio signals from a control station to guide an airplane between airports or sea lanes. Its success led to the development of other automatic pilots that are still in use today. Sperry's wife called her husband's invention a "servo" because it could be used to maintain any type of equipment such as radios or cameras that required regular maintenance work.

Sperry originally wanted to call his invention a "control system", but his wife insisted on calling it a "servo". So, "servo" has been adopted as the official name by the manufacturers association.

What is a servo mechanism?

A servomechanism, often known as a servo, is a self-correcting device that employs error-sensing feedback to improve the performance of a mechanism. The word "really" refers to systems in which feedback or error-correction signals aid in the control of mechanical position or other parameters. For example, a conventional radio receiver uses feedback from an antenna to correct for signal distortion caused by passing through distant ground clutter. A servo system can use similar principles to correct for errors in positioning a mechanical element such as the mirror in a laser scanner.

Servos are widely used in industrial robots to make them more flexible and capable of working in restricted spaces. Other applications include spacecraft instrumentation, military equipment, and personal computer peripherals.

The first true servo was invented by Willis Whitney Alvord in 1915. He called his invention the "self-regulating mechanism." Although modern servos have many improvements on Alvord's original design, they still contain several elements that would be found in today's servos including sensing devices, electrical circuitry, and fluid cylinders.

Alvord's invention was not popular at the time because it required skilled engineers to build and operate it. It was also very expensive -- one estimate is that it cost $10,000 in today's money. However, it did lead to later developments in servo technology that were available when World War II began.
