Description
Product details
A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. The VFD also has the capacity to control ramp-up and ramp-down of the motor during start or stop, respectively. A VSD controls the speed and torque of an AC motor by converting fixed frequency and voltage input to a variable frequency and voltage output. A VVVF (Variable Voltage Variable Frequency) drive controls the speed and torque of an AC motor by adjusting the frequency and voltage of the power supplied to it. This is achieved through a process involving a rectifier, a DC link, and an inverter. In a Variable Frequency Drive (VFD), an Insulated Gate Bipolar Transistor (IGBT) is a crucial component that acts as a high-speed electronic switch, controlling the flow of power to the motor. It enables precise and efficient motor speed and torque control by rapidly switching on and off, converting DC power back into AC power with a variable frequency and voltage.
