Motor Driven Variable Resistor

Motor Driven Variable Resistors, also known as rheostats or potentiometers, are a type of resistor that can be adjusted manually or by a motor to vary the resistance in an electrical circuit. They are commonly used in various electrical and electronic equipment for controlling voltage, current, or signal levels.

These resistors consist of a resistive element, typically made of a wire or carbon composition, and a movable contact that can be adjusted along the resistive element. By changing the position of the contact, the resistance value can be varied, allowing for precise control of the circuit parameters.

Motor driven variable resistors are often used in applications where continuous adjustment of resistance is required, such as in volume controls, dimmer switches, and motor speed controls. They can be operated manually by turning a knob or remotely by using a motor to drive the adjustment mechanism.

In the supply class Resistor, which falls under the supply group Electrical and Electronic Equipment Components, motor driven variable resistors are available in various specifications, including different resistance values, power ratings, and mounting options. These resistors can be sourced from suppliers specializing in electrical and electronic components.

When selecting a motor driven variable resistor, it is important to consider the specific requirements of your application, such as the desired resistance range, power handling capability, and physical dimensions. Additionally, it is advisable to consult the datasheets and technical specifications provided by the supplier to ensure compatibility with your circuit design.

Overall, motor driven variable resistors are versatile components that offer precise control over resistance in electrical circuits, making them essential in many electrical and electronic applications.
