AC Motor Drive

We are offering ac motor drive. With modern power electronics and advanced microprocessor technology, sakthi's ac motor drives are able to efficiently control motor speed, improve machine automation and save energy. Taking advantage of our strong position in power electronics technology, sakthi's vfd series of ac motor drives has evolved rapidly. Each drive series is designed to meet specific application needs. Our ac drives accurately control speed and torque, smoothly handle an increased load, and provide numerous custom control and configuration operating modes. Our ac motor drive product line provides a full range of motor control technologies and is used throughout a wide range of industries, to enhance and improve machine automation.
backed by our team of experts, we are able to offer a wide range of motor drives that is available with a constant voltage limit charger with advanced technology and is available in various sizes.
