A pole-changing centrifuge system uses specially designed squirrel cage induction motors that change speed by varying the number of stator poles. The system is primarily used in industrial centrifuges where different process stages require specific, fixed speeds
Centrifuges operate in stages:
1.Charging (low speed)
2.Acceleration (medium speed)
3.Separation (high speed)
4.Discharging (low or reverse speed)
Having multiple fixed speeds enhances process control while maintaining simplicity.
1.No VFD Required: Avoids electronic complexity and harmonics.
2.Cost-Effective: More economical for applications not requiring continuous speed variation.
3.Robust and Reliable: Fewer electronic components mean reduced failure rates.
4.Good for Explosion-Proof Areas: Preferred in hazardous environments like chemical plants.
1.Fixed Speeds Only: Not suitable for processes requiring fine speed adjustments.
2.Larger Motors: More complex windings may increase motor size and weight.
3.Limited Flexibility: Less adaptable than VFD systems in dynamic environments.
1.Pharmaceutical Industry – for product separation.
2.Food Processing – for decanting and filtering.
3.Chemical Plants – where safety and rugged operation are critical.
4.Textile and Dyeing Units – for different process speeds
