Circuit measures currents in dc
12/06/2001 EDN - Design Ideas / The simple
circuit design in Figure 1 lets you measure all
components of a current flowing in a dc servo
motor. The rectified output of the circuit uses
ground as a reference, so you can measure the
output by using a single-ended A/D converter.
The current-sense resistor, R1, has a value of
Servo Slew Rate Control:
A circuit that limits the rate of change of a
signal; a feature of this design is that the
positive and negative rates can be different.
Servo-motor acceleration control

Whenever the speed of a dc servo motor must be
controlled with absolute accuracy, there’s no
substitute for tachometer-based feedback
combined with a fullblown servo loop. But in
other applications, adequate steady-state
precision and sometimes. .
