3 & 4 Speed Pole-Changing Centrifuge System

A 3 & 4 Speed Pole-Changing Centrifuge is a type of centrifuge that utilizes an induction motor with multiple stator windings, allowing the motor to operate at different fixed speeds by changing the number of magnetic poles. This design enables the centrifuge drum to rotate at predefined speed levels, which can be selected based on the specific requirements of the separation process.

Centrifuges function by separating components in a mixture based on differences in density, typically by spinning the mixture at high speeds. In a pole-changing centrifuge, speed control is achieved not through variable frequency drives but by altering the motor’s pole configuration, offering a simple and robust method for stage-wise speed control.

This system is particularly effective in applications where consistent speed stages are sufficient to achieve efficient separation, such as in sugar manufacturing. It allows for precise operation during critical phases like charging, spinning, and discharging, while also minimizing complexity and maintenance. The design of PLC based contactors control system makes it a reliable and low-maintenance solution for continuous, heavy-duty industrial use.
