Variable frequency drives for linear motion .

The terms "variable frequency drive" (VFD) and "variable speed drive" (VSD) are often used interchangeably, although there is a distinction between the two. A VFD controls AC motor speed by varying the frequency of the voltage supplied to the motor, while a VSD can control the speed of either an AC or a DC motor, and can do so via mechanical, electrical, or hydraulic means.

What is a variable frequency drive? | Danfoss

A variable frequency drive (VFD), also known as AC variable speed drive, AC variable frequency drive, VFD inverter or variable voltage variable frequency drive, is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. VFD control also has the capacity to control ramp-up and ramp-down of the motor during start or stop, respectively.

Variable frequency operation Hence the speed of the motor depends on the applied frequency, as well as the winding arrangement, and a little on the load. Therefore in order to control the motor speed it is necessary to control the frequency of the supply. If the frequency is reduced, the voltage must be reduced or the magnetic flux will
