Many electric motors operate under conditions of frequent changes of operating modes (starts and stops, variable load). Frequency converters allow the motor to start smoothly, reduce the maximum starting torque and heating of the equipment. This is important, for example, in hoisting machines and allows you to reduce the negative impact of sudden starts.

With the help of the frequency converter, it is possible to smoothly regulate the operation of blowing fans, pumps and allows you to automate technological processes.

The use of frequency converters in conveyors, conveyors, elevators allows you to increase the service life of their components, as it reduces jerks, shocks and other negative factors when starting and stopping equipment. They can smoothly increase and decrease the engine speed, carry out reverse movement, which is important for a large number of high-precision industrial equipment.

A soft starter is a mechanical, electrical (electronic) or electromechanical device used to soft start (stop) electric motors with a small starting torque (for example, with a fan characteristic).

A soft starter is a device that is necessary to control the process of starting, operating and stopping electric motors, providing smooth acceleration, soft stopping, decreasing the starting current, matching the motor torque with the load torque.
