Examples

Een frequentieregelaar (of ook drive genoemd – variable frequency drive) is een type motorregelaar dat een elektromotor aandrijft door de frequentie en spanning van de voeding te variëren. De drive is ook in staat om het aan- en uitlopen van de motor tijdens respectievelijk het starten en stoppen van de motor te regelen.

“A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current (AC) of one frequency to alternating current of another frequency.

A variable-frequency drive is a type of frequency changer used for speed control of AC motors such as used for pumps and fans. The speed of an AC motor is dependent on the frequency of the AC power supply, so changing frequency allows the motor speed to be changed. This allows fan or pump output to be varied to match process conditions, which can provide energy savings.”
