RAILWAY AC/AC VARIABLE FREQUENCY DRIVES
Railway VFDs: Moving forward with new solutions
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.
