Features and Benefits
Step pulleys are driven by a belt system that is manually changed to achieve a specific speed. They commonly feature 8 or 16 fixed speeds.
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.
