SERVO MOTOR
Servo
Motor : as compared to traditional
DC or AC motors, servo motors had
advantage of motor feedback. This
feedback can be used to detect unwanted
motion, or to ensure the accuracy of the
commanded motion. The feedback is
generally provided by an encoder of some
sort. Servos, in constant speed changing
use, have a better life cycle that
typical a/c wound motors. Servo motors
can also act as a brake by shunting off
generated electricity from the motor
itself. |
