Variable Speed Drives and Frequency Drives
Variable Frequency Drives (VFDs) and Variable Speed Drives (VSDs) help regulate motor speed, torque, and energy use across industrial and commercial applications. These AC drives support motor control by matching output to actual load demand, rather than running equipment at full speed. A VFD converts incoming AC power into DC through a rectifier, smooths the DC supply with capacitors, and then uses an inverter to convert it back into controlled AC output. By adjusting frequency and voltage, energy-efficient drives help improve speed regulation, reduce energy waste, and support reliable operation in pumps, fans, compressors, HVAC systems, machines, and process equipment. For cost-sensitive industrial motor control projects requiring precise speed regulation, energy efficiency, and predictable operational costs, shortlisted VFD options include Easy Altivar 310 and Altivar 12. Altivar Machine ATV320 may also be considered where applications need more advanced machine control.
