A typical Servo looks like a rectangular box with a motor shaft coming out of one end and a connector with three wires out of the other end. The three wires are the power, Control, and Ground. Servos work with voltages between 4 and 6 volts. The control line is used to position the servo. The servo motor comes in different sizes, which affect the overall size of the servo. The gears of a servo vary from servo to servo. Inexpensive servos have plastic gears, and more expensive servos have metal gears which are much more rugged but wear faster. The potentiometer of a servo is the feedback device. The electronics of a servo are pretty much the same in all servos, but the output shaft bearing of a servo has either a plastic on plastic bearing that will not take much side load or a metal on metal bearings that stand up better under extended use, or ball bearings which work best. We highly recommend ball bearing servos if your application demands heavy side loads.

How is the Servo Controlled?
Servos are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire. There is a minimum pulse, a maximum pulse, and a repetition rate. A servo motor can usually only turn 90° in either direction for a total of 180° movement. The motor's neutral position is defined as the position where the servo has the same amount of potential rotation in the both the clockwise or counter-clockwise direction. The PWM sent to the motor determines position of the shaft, and based on the duration of the pulse sent via the control wire; the rotor will turn to the desired position. The servo motor expects to see a pulse every 20 milliseconds (ms) and the length of the pulse will determine how far the motor turns. For example, a 1.5ms pulse will make the motor turn to the 90° position. Shorter than 1.5ms moves it in the counter clockwise direction toward the 0° position, and any longer than 1.5ms will turn the servo in a clockwise direction toward the 180° position.
When these servos are commanded to move, they will move to the position and hold that position. If an external force pushes against the servo while the servo is holding a position, the servo will resist from moving out of that position. The maximum amount of force the servo can exert is called the torque rating of the servo. Servos will not hold their position forever though; the position pulse must be repeated to instruct the servo to stay in position.
Frequently Asked Questions
What is the difference between a wire and a cable?
The core of the differentiation between wire harnesses and cable assemblies lies in the fact that wires and cables are two entirely separate things. A wire is a single strand of a conductive material like tin or copper. Once a bundle of wires is twisted or braided together and contained within a protective outer sheath, they have become a cable.
Why are wire harness & cable assembly often confused?
By nature, both wire harnesses and cable assemblies contain cables and wires. The main difference is in the engineering of the component to match the application. Wire harnesses are low-cost means with which to provide a bundle of cables and wires some degree of protection, while keeping them organized for ease of installation and future service. Cable assemblies provide a much more robust protection by keeping components snug within a rugged outer sheath. Cable assemblies are meant to be used in demanding environments where things like heat, friction, or moisture could prematurely wear out a cable or wire.
