Features and Benefits
Variable speed pulleys are driven by a V-shaped belt system and a variable speed assembly that regulates an infinite speed range change by the turn of a dial.
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.
