Variable frequency drives (VFD) allow us to control and regulate the AC rotational motor speed and torque by varying motor input frequency and voltage are usually placed between the power supply and the motor.
Electric motors are present in thousands of applications and allow the operation of electrical appliances, fans, pumps, machines, etc. These motors need electrical energy to operate and provide speed to the elements where they are installed. This means that the AC motors will run at the right speed according to demand. In addition to saving energy, the VFD (known as frequency converter as well) also helps to reduce maintenance costs and noise emissions.
Why using an VFD? Here are some benefits to it:
- Save energy and improve network, systems, and HVAC efficiency
- Easy control of motor speed, flow and pressure in electric pumps and fans
- Soft start of motors
- Reduction of temperature and less maintenance of connected devices
- Match the speed and power of the drive to the process requirements
