Drives and Soft Starters

A wide range of AC variable frequency drives (VFD) is available for motor speed control and other industrial control applications. Drives are available from a range of trusted brands including WEG, Toshiba, and AutomationDirect's DURApulse/GS series and IronHorse series.

Micro variable frequency drives (VFD) offer an affordable price in a compact footprint. For applications with smaller motors, many micro drives support single-phase input power and some have high-end features such as vector control or a built-in PLC. Micro drives are available in sizes up to 10hp.

General purpose variable frequency drives enable speed control for AC motors such as those in conveyors, fans, pumps and material handling. Various models offer V/Hz, sensorless vector or field oriented vector control modes. General purpose drives are available in sizes up to 30hp.

High-performance AC drives are usually specified when a high degree of precision in speed control is required, when full torque is needed through the speed range of the motor, or if a torque control mode is required. They offer advanced features such as STO, closed-loop vector control and a built-in logic controller. High-performance drives are available in sizes up to 300hp.

NEMA 4X-rated drives are suitable for washdown-duty applications. They offer V/Hz, sensorless vector or field oriented vector control up to 30hp, depending on series.
