Starting Principle of Variable Frequency Distribution Box
A variable frequency drive, also called frequency inverter, adjustable speed drive, the basic working principle is adjusting the electrical supply to an AC motor with a corresponding frequency and voltage change in the motor's speed and torque output. The core working principle of a VFD involves converting incoming AC power to DC, and then transforming it back to AC with a variable. The term “variable frequency drive” refers to a category of motor controllers that can be used in a wide variety of applications, ranging from home electronics to industrial compressors and more The variable frequency drive, or VFD, is primarily used to drive and control the speed and torque of the. Variable Frequency Drive (VFD) is the type of AC motor drive that controls the speed and the torque. It can control the speed by changing the frequency of the current. Think of it as a sophisticated dimmer.
