Why use a variable frequency drive VFD?
Jun 16 , 2022

1. Reduce energy consumption and energy costs If your application does not require full speed operation, you can reduce energy costs by using a variable frequency drive to control the motor, which is one of the advantages of variable frequency drives. VFDs allow you to match the speed of motor-driven equipment to load requirements. No other AC motor control method will allow you to achieve this. 2...
