An AC Drive or Variable Frequency Drive (VFD) is a power control device that converts a fixed-frequency AC power source (e.g., grid-supplied 50Hz or 60Hz AC) into an AC power source with adjustable voltage and frequency to drive an AC motor.
This conversion process allows precise control of the motor’s speed, resulting in more efficient energy utilization, smoother starting and stopping, and more precise process control.
All of these motors rely on electricity to operate. In order to do their job of providing torque and speed, motors require a corresponding amount of electrical energy. All these motors provide the required torque or speed by consuming electricity.
Inverters convert fixed frequency AC power into variable frequency, variable voltage AC power.
Let us see how this is done below:
- 1.converts the incoming AC power into DC power
- 2.Smooth DC waveform
- 3.Inverters convert DC power to AC power
- 4.Calculation and repetition
Recommended models of ABB frequency converters
ABB frequency converters are used to control and regulate the speed of three-phase AC asynchronous motors.
They have stable performance, rich combination functions, high-performance vector control technology, low-speed high torque output, good dynamic characteristics, and super strong overload capacity. The main models include AZY-FC6810, AZY-FC6845,etc.
