What is variable frequency drives?

Variable frequency drives (VFDs) are a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for VFDs are variable speed drives, adjustable speed drives, adjustable frequency drives, AC drives, micro drives, and inverter drives. VFDs are used in applications ranging from small appliances to large compressors. About 25% of the world's electrical energy is used by electric motors in industrial applications. VFDs can reduce energy consumption and improve system performance by matching motor speed to the actual process requirements, leading to significant energy savings and improved process control.

motor starts

Motor starters (e.g., across-the-line starters) offer basic motor control functionality, serving as a simpler, less efficient alternative to VFDs, especially in applications that don't need variable speed control.
