Quizplus · Accepted Answer

A variable-frequency drive (VFD) controls the frequency of the electrical supply to the motor, allowing for precise control over the speed and torque of the motor. This is important in many industrial and commercial applications where varying the speed of the motor can improve efficiency and reduce wear and tear. Standard-frequency and voltage drives do not offer this level of control.
