High Performance

High-performance variable frequency drives (VFD) enable speed control for three-phase AC motors such as those in conveyors, fans, pumps, HVAC and material handling. Available in sizes up to 300hp offer advanced features such as STO, closed-loop vector control and a built-in logic controller. High-performance AC drives are top-of-the-line drives that 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 (full torque available at very low or zero speeds), or if a torque control mode is required (controlling and maintaining torque as opposed to speed).
