Servo Motor Position Control
Basically, pulse width modulation is used for servo motor position control
allowing a rotation limit of from 90 to 180. These servo motors are applied
in areas, where precision positioning is crucial. Such applications include
control of robotic arms and legs, RC helicopter toys and sensor scanners.
The position where the servo motor can potentially move in either clockwise
or anticlockwise direction is generally referred to as the neutral position.
Through sending an electrical pulse of variable width to the motor, the
position of the shaft can be determined and the rotor turns to the anticipated
position based on the duration of this pulse. In every 20 ms, a pulse is
expected by the servo motor in order to operate. It is also good to note that
the length of this pulse determines how far the motor will turn. The servo
resists from moving out of a position if an external force tries to move it out
of this position. The servo can exert a maximum force known
