A servo drive is an electronic amplifier used to power electric servomechanisms. ... or computer, which analyses incoming signals while controlling the mechanism. The ...
In 2001 the company introduced a line of equipment designed to provide repair shops and plant maintenance personnel the ability to test run many types of servo motors with one common drive device. A patent was later issued to the company for "an apparatus that allows a non-standard brushless motor to be driven with a standard drive amplifier." [2]
Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...
Following a specified motion trajectory is called servoing, [4] where "servo" is used as a verb. The servo prefix originates from the Latin word servus meaning slave. [1] The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed, attitude or any other measurable variables. [5]
Embedded servo or wedge servo is a type of servo configuration used on hard disks. Embedded servo systems embed the feedback signals for the read/write head positioner (usually a voice coil motor) inside gaps (wedges) in the data tracks of the disk. This setup allows the entire set of platters to be used, instead of having to reserve one or two ...
Until the early 1980s the majority of servo drive systems used to control motion in industrial machinery were based upon analog electronics.The accepted interface to control such devices was an analog voltage signal, where polarity represented the desired direction of motion, and magnitude represented the desired speed or torque.
A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...
For certain forms of computer data storage, however, such as modern hard disk drives and some tape drives, degaussing renders the magnetic media completely unusable and damages the storage system. This is due to the devices having an infinitely variable read/write head positioning mechanism which relies on special servo control data (e.g. Gray ...
