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.
Single-phase refers to one phase line (coil) that connects to and runs voltage through the motor. Single phase lines are not as efficient as three-phase motors. Machine phase would commonly match the type of electrical current used in the facility.
