Rotary Potentiometers, Rheostats Overview

Rotary potentiometers, also known as rheostats, are two-terminal resistive components that feature adjustable resistance. These components are used in a wide range of analog applications, such as voltage control and current regulation. The resistance of a rheostat is determined from the contact area between the two terminals and the adjustable resistance arm. The resistance between the two terminals can be adjusted by either turning the arm or moving it along its length.Rotary potentiometers, rheostats, are most often used for voltage dividers. These are circuit elements where a resistive material is used to divide a voltage such that the output voltage is a fraction of the input voltage. This is useful in applications where precise control of the output voltage is needed. Rheostats are also used to control large currents, such as those used in motor control applications.

6373R20KL.5 Application Field and Working Principle

The 6373R20KL.5 is a rheostat manufactured by Motorola. The 6373R20KL.5 features an adjustable resistance of 20K ohms and is suitable for use in motor control applications. The rheostat features a four-terminal surface-mount design with an adjustable arm and an insulation sleeve.The 6373R20KL.5\'s working principle is based on a voltage divider configuration. The voltage divider circuit uses the two terminals of the rheostat as its two resistors. A voltage is applied across the two terminals, and the arm of the rheostat is then adjusted to adjust the resistance. This changes the output voltage of the circuit, which allows for precise control of the output voltage.The 6373R20KL.5\'s application field is mainly motor control. The rheostat can be used to regulate the current in an inductive load, such as a motor. By adjusting the arm of the rheostat, the current can be accurately controlled. This can help to reduce power consumption, improve accuracy, and extend the life of the motor. The rheostat is also suitable for use in voltage regulation applications, such as battery chargers and AC power supplies.
