What is the Efficiency super premium IE4 in motors?
The term IE4 corresponds to an international standard established by the IEC (International Electrotechnical Commission) to classify the energy efficiency of electric motors. An IE4 motor is considered one of the highest efficiency categories currently available in the industry for induction and/or permanent magnet motors.

Key Benefits of a motor with IE4 efficiency.
Significant Energy Savings
An IE4 motor can be up to 30-40% more efficient than an IE1 motor of the same power. Compared to the next lower category (IE3), the additional efficiency can be around 1-3%, which translates into thousands of kWh of savings per year in heavy use.
Lower Heat Emission
By wasting less energy as heat, the motor operates at lower temperatures, prolonging its service life and reducing the need for additional cooling systems.
Reduced Operating Costs
A more efficient motor means lower electricity bills. Since compressors typically operate many hours per day, the energy savings can be highly significant, directly impacting production costs.
Reliability and Durability
With less wear and tear from heat generation and vibration, the IE4 motor offers longer life and requires less periodic maintenance.
Sustainability and Regulatory Compliance
Many countries and regions are implementing stricter regulations for energy efficiency and CO₂ emission reduction. By incorporating IE4 motors, you comply with the most stringent standards worldwide and contribute to your company's environmental responsibility.
Optimal Performance at Low and Medium Load
Thanks to permanent magnet technology and/or optimized design, these motors maintain high levels of efficiency even when not running at 100% capacity, which is ideal for compressors with variable frequency drive.
Why choose a compressor with IE4 motor
Integration with Variable Frequency Drive
The XS Series compressor features a variable frequency control system, which adjusts motor speed according to compressed air demand.
An IE4 motor with permanent magnet technology is further enhanced by this feature, allowing the compressor to operate with only the energy needed at any given time.
Constant Pressure and Stability
By responding quickly and accurately to speed changes, the IE4 motor facilitates very stable pressure control at ±0. 01 MPa.
This results in uniform compressed air quality, essential for applications requiring accuracy and consistency.
Increased Operational Availability
With lower heat-up and a reliability-focused design, the compressor can operate continuously (100% duty cycle) without incurring frequent shutdowns due to overheating.
That translates into more uptime and less downtime.
Accelerated Return on Investment (ROI)
Although an IE4 motor and its control system represent a slightly higher initial investment, the cost difference is more than compensated by the energy savings in the medium and long term.
In industrial environments where the compressor works several hours a day, ROI can be achieved in a few months.
