Energy-Efficient Motor Retrofit For Vacuum Melting Furnace | CIITTO SERVO Case Study
Energy-Efficient Motor Retrofit for Vacuum Melting Furnace | CIITTO SERVO Case Study
Project Overview:
To address issues of high power consumption, overheating, and noise in Xiawu New Energy’s vacuum melting furnace, CIITTO SERVO implemented a motor transformation using our high-efficiency PMSM solution. The result was a significant 18.8% increase in energy efficiency.
Before Retrofit
- High current draw
- Severe motor surface heating (54°C)
- Excessive noise
- No variable frequency functionality
- High energy consumption
- Output power: 10.1 kW
After Retrofit
- Lower current and surface temperature (41°C)
- Reduced noise
- Integrated variable frequency driver
- Energy efficiency improved by 18.8%
- Output power reduced to 8.2 kW
