Three Phase Variable Frequency Drive is an important tool for manufacturers and building owners to improve energy efficiency, reduce costs, and increase the lifespan of their equipment. This drive adjust and vary the frequency of the electricity supplied to the motor, hence the term variable frequency drives. This allows the motor to operate at different speeds, resulting in greater efficiency and energy savings. Apart from that, this is required to control the speed of AC induction motors in various applications such as industrial machinery, HVAC systems, and electric vehicles.
