ServomotORs are available as AC OR DC motORs. Early servomotORs were generally DC motORs because the only type of control fOR large currents was through SCRs fOR many years. As transistORs became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotOR became used mORe often. Early servomotORs were specifically designed fOR servo amplifiers. Today a class of motORs is designed fOR applica-tions that may use a servo amplifier OR a variable-frequency controller, which means that a motOR may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motOR a servo system, so it is possible fOR a simple AC induction motOR that is connected to a velocity controller to be called a servomotOR.

As a programming language, C is rather like Pascal OR FORtran.. Values are stORed in variables. Programs are structured by defining and calling functions. Program flow is controlled using loops, if statements and function calls. Input and output can be directed to the terminal OR to files. Related data can be stORed together in arrays OR structures.
