Proven IE5 SynRM Solutions Deliver Over 34% Energy Savings in Industrial Mixing Applications
Industrial mixing equipment is widely used in industries such as chemical processing, new energy materials, mining, building materials, and manufacturing.
Because mixing systems usually operate for long hours under continuous-duty conditions, the motor system becomes one of the major sources of energy consumption.
Traditional three-phase asynchronous induction motors are commonly used in mixing equipment. However, with increasing electricity costs and stricter energy efficiency requirements, many companies are upgrading to high-efficiency motor solutions.
By replacing traditional IE3 induction motors with IE5 synchronous reluctance motor (SynRM) systems, HUIMA has successfully completed multiple energy-saving retrofit projects in the mixing industry.
The practical application results show:
Energy savings of 34%–36%
Investment payback within 1.4–1.7 years
Significant reduction in electricity consumption and carbon emissions
Improved efficiency for continuous industrial operation
These successful projects demonstrate the excellent energy-saving potential of IE5 SynRM technology in mixing applications.
Before retrofit, the mixing equipment used traditional:
IE3 Three-Phase Asynchronous Motor
Main challenges:
Rotor copper losses during operation
Higher energy consumption under long-term running conditions
Limited efficiency improvement potential
After upgrading to HUIMA IE5 SynRM system:
IE5 Synchronous Reluctance Motor + Drive System
Advantages:
IE5 ultra-high efficiency performance
No rotor copper loss
Magnet-free rotor structure
Lower operating losses
