muuttuvanopeusajuri
A muuttuvanopeusajuri, which translates to variable speed drive (VSD) or adjustable speed drive (ASD) in English, is an electronic device used to control the speed of an electric motor. These devices work by varying the frequency and voltage supplied to the motor, thereby altering its rotational speed. The primary benefit of using a VSD is energy savings, as motors can be run at lower speeds when full power is not required, significantly reducing electricity consumption.
Beyond energy efficiency, VSDs offer several advantages. They provide precise control over motor speed, allowing for
The technology behind VSDs typically involves power electronics such as transistors or thyristors to manipulate the
