Introduction and application environment of frequency-sensitive potentiometer

Frequency-sensitive potentiometer is a static non-contact electromagnetic component, which is widely used in occasions where current needs to be adjusted according to frequency. Its structure is similar to the secondary winding of a three-phase transformer, but it has higher iron loss characteristics and is mainly used for starting and regulating three-phase AC asynchronous motors.Not only does it perform well in data, inductor coil custom wholesale In the market share, it is also gradually expanding, so that more people can benefit. https://www.lbcoil.com/

Frequency-sensitive potentiometer is particularly suitable for three-phase AC asynchronous motors with a power of 22kW and 50Hz. It is often used in equipment that occasionally needs to start light and heavy loads, such as water pumps, air compressors, rolling mills, etc., or equipment that needs to start frequently in a short time, such as 2.2kW to 125kW bridge cranes, hoists, mine conveyor belts, etc.

Applicable environment:

Frequency-sensitive potentiometers have clear environmental requirements to ensure their long-term stable operation:

Altitude: not more than 4000 meters;

Ambient temperature: maximum not more than +40¡æ, minimum not less than -30¡æ;

Air humidity: relative humidity not more than 85% (20¡À5¡æ);

Protection requirements: prevent rain and snow, avoid long-term exposure to water vapor environment;

Vibration and shock: general vibration and shock are allowed;

Installation angle: can be installed at any angle and vertical tilt angle;

Environmental conditions: It is forbidden to use in an environment with explosive gas or corrosive media to avoid metal damage insulation or the presence of conductive dust.

In summary, frequency-sensitive potentiometers have broad application prospects and are suitable for the start-up and control of a variety of industrial equipment. Their special design enables them to adapt to a variety of environmental conditions and provide reliable current regulation functions.
