servo amplifier

"But this is only a temporary fix; when we have more time I want to replace that lateral servo amplifier.

A servo amplifier indicates an integrated feedback loop to actively control the output at some desired level.

The 6550 was developed by Tung-Sol in 1955 originally for use as a servo amplifier.

An AC servo amplifier, a linear power amplifier, feeds the control winding.

The Ragonnet power reverse mechanism was a general purpose air or steam-powered servo amplifier for linear motion patented in 1909.

Specifically designed for audio amplification, the KT88 has similar ratings to the American 6550 which was designed for use as a servo amplifier.

A different type of receiver, called a control transformer (CT), is part of a position servo that includes a servo amplifier and servo motor.

Also the Servo Amplifiers, picking off the tiny Gyro signals and amplifying this to control the platform gimbalmotors, have tight specifications.

Care must be taken when using these servos to avoid stalling them against the end-stops as large currents will be drawn by the servo amplifier that may eventually cause permanent damage.

A key feature of the Indramat servo was the programming module (called a "Personality Module" in the North American market), which contained all variable settings required to match the servo amplifier with a given motor.

The servo amplifier circuitry is mounted on a small printed circuit board that fits within the case of the servo mechanics and the user is presented with three colour coded wires that terminate at a miniature plug or socket.

Although there are many configurations, most CNC routers have a few specific parts: a dedicated CNC controller, one or more spindle motors, servo motors, servo amplifiers, AC inverter drives, linear guides, ball nuts and a workspace table or tables.

Fortunately all of the electronics for the servo amplifier is usually contained within custom designed integrated circuits and interested readers should refer to the data sheets and application notes for the Signetics NE 544, the Plessey ZN 409 and the Exar XR-2264 for further information.
