By changing the voltage and frequency of the power, AC Drives can change the speed of AC motors. They are installed for stepless speed controlling of squirrel cage induction motors in manufacturing and other plants. They are designed using high-grade rectifier and inverter units for converting AC to DC voltage and vice-versa. These AC Drives come with varied advantages such as large energy savings, enhanced life of rotating components and reduced noise and vibration level. In addition to this, they are also ideal to reduce thermal and mechanical stresses to enhance the quality and productivity.
