AC drives or Variable frequency drives control speed, torque, acceleration, deceleration, and rotation direction of AC motors. AC drives save energy by tailoring the power delivered to meet the actual load requirements. AC drives replace mechanical gearboxes, belts, hydraulic couplings, DC drives, servo-drives, or eddy current drives in many situations. AC drives provide an accurate and wide range...
