3590S-2-502L potentiometer potentiometer connection (or trim resistors etc.) conventional pin (for example, said there are only three pins potentiometer), the resistance value is fixed at both ends, the middle pin on either end pin resistance value is variable; he is equivalent to starting middle pin from the potentiometer resistance is divided into two series, the total resistance of the series is fixed; therefore, if used as a variable voltage divider resistors, the end then the input voltage, the output of intermediate termination, remaining grounded; if used as a variable resistor, one end of the input voltage, the output of intermediate termination, the remaining end is floating, or intermediate end; both sides of the foot is a wholly potentiometer resistance, the intermediate node sliding feet, a foot access power from both sides of the foot from the middle leads, can be varied with the rotation of the intermediate pin voltage. DC motor speed varies with the applied voltage, so that rotation of the intermediate voltage pin change, to change the motor speed. Positive and negative changes in DC power supply, you can make the motor reversal, the potential does not have this feature.
