Features and Benefits
Electronic Variable Speed control (EVS, are similar to variable speed pulleys, but the speed is controlled electronically rather than manually by turning a dial. They feature several speeds within a specified speed range.
Three-phase refers to three individual lines (coils) that connect to and run voltage through the motor. Each line alternates in a sequence as they reach their voltage peak. They provide a more stable flow of voltage and more horsepower to the equipment.
