Vacuum Pump Motor Retrofit – Energy Saving Case Study
In this energy-saving project, a vacuum pump originally driven by an asynchronous motor was retrofitted with a Ciitto Servo permanent magnet synchronous motor. The objective was to reduce operating power consumption while maintaining consistent load performance.

Performance Comparison
| Condition | Loading Capacity (KG) | Operating Time (Min) | Pre-operation Data (kWh) | Post-operation Data (kWh) | Cycle Energy Consumption (kWh) | Energy Saving Rate per Unit Time (%) | Energy Saving Rate per Unit Output (%) |
|---|---|---|---|---|---|---|---|
| Before | 642 | 1691 | 5141.04 | 5233.87 | 92.83 | — | — |
| After | 642 | 1698 | 3925.75 | 4001.09 | 75.34 | 19.17% | 18.84% |
Summary
Before: Asynchronous motor average power: 3.4 kW
After: Synchronous motor average power: 2.9 kW
This retrofit achieved an average operating power reduction of approximately 14.7%, while improving energy efficiency and performance consistency.
