A variable frequency drive, known as a VFD, is an electronic drive system used to control electric motors. Its purpose is varying motor speed by controlling input frequency and voltage. Variable frequency drives convert AC voltage to DC current and can be thought of as "pulsing" this DC current to the motor to vary the motor speed. Variable ...AC Motor Drive systems utilizing variable frequency controls produce high frequency electrical noise. The noise is superimposed on the power drive lines of the motors in the form of common mode noise. The common mode noise creates a voltage (dv/dt) across the rotor/stator of the motor resulting in a discharge current through the motor bearings to

Global Variable Frequency/Speed Drives (VFD/VSD) Market Report 2013 - 2017. Variable Frequency Drives: An Explanation Introduction Conventionally, motors are connected directly to a power source with switches that determine on/off functionality. When the motor is needed, the power source turns the motor on abruptly. This leads to a high initial current surge, or inrush current, What is a variable frequency drive or adjustable speed drive? Variable frequency drives (VFDs), also called adjustable speed drives (ASDs), allow induction-motor-driven loads such as fans and pumps to operate at increased efficiency. By controlling motor speed so that it finely corresponds to varying load requirements,

Figure 3 demonstrates volt-age and frequency being increased up to the base speed. At base speed, the voltage and frequency reach the rated values as listed in the nameplate. We can drive the motor beyond base speed by increasing the frequency further.

The overall frequency for the VFD output signal to the motor will be determined by the frequency of the PWM sine wave. The frequency can be adjusted from 0 - 400 Hz on some VFDs and typically it can be adjusted from 0 - 120 Hz. The amplitude of the signal will change to change the voltage of the signal.controller capable of providing a standard three phase AC induction motor with variable frequency and voltage. 2.
