Frequency converters - An important device in production

A frequency converter is particularly important in production as it can vary the frequency which directly affects the rotational speed of the asynchronous motor it controls.

An adaptation of the rotational speed can be used for energy saving in, for example, ventilation and cooling systems, so that the motor can run at low speed when not much cooling or ventilation is needed.

It can also be used in practical terms to ensure that the engine runs at a speed that suits the purpose.
