Transfer function

A mathematical expression or a graph that expresses

the relationship between the outgoing and the

incoming signals of a process or control element. An

important property of motors is that their response to a

pure sinusoidal current signal is also sinusoidal at the

same frequency. Suppose a pure sinusoidal current

signal at frequency

and amplitude

is injected

into a motor, and the motor speed is sinusoidal with an

amplitude

and phase

relative to the current

signal. The transfer function of the motor at the

frequency

therefore has an amplitude and

phase

AB /

(Figure G-4).
