Product Overview


The Efficient EC Motors with Inverter for Industrial represent a breakthrough in industrial drive technology, combining premium motor efficiency with integrated variable speed control. These IE4 ultra-premium efficiency motors deliver up to 75% energy savings compared to conventional induction motors, with power ratings ranging from 0.75 kW to 15 kW . The integrated inverter eliminates the need for external variable frequency drives (VFDs), reducing installation complexity and electromagnetic interference . With Class F insulation and IP55 protection, these motors withstand harsh industrial environments including dust, vibration, and temperature fluctuations from -15°C to 60°C . Compliance with IEC 60034-30-1 and UL 1004 standards ensures global acceptance across manufacturing sectors.


Product Features


Inverter-Driven Precision

The integrated inverter provides 0.1-50 Hz speed control with vector control technology, enabling precise torque regulation down to 1% of rated load . This makes the motor ideal for applications requiring accurate speed or tension control, such as conveyor systems and pumps.


Energy Optimization

Advanced power factor correction maintains >0.95 PF across 25-100% load, eliminating reactive power penalties common with traditional motors . The motor’s efficiency exceeds 94% at full load and remains above 89% even at 50% load, outperforming IE3 motors by 8-12% in partial load conditions.


Industrial Connectivity & Protection

Offers PROFINET, EtherCAT, and Modbus TCP communication protocols for seamless integration into industrial automation systems . Comprehensive protection includes overcurrent, overtemperature, phase loss, and short-circuit safeguards to maximize uptime.


Applications


Conveyor Systems

Precise speed control optimizes material handling in automotive, packaging, and logistics facilities, reducing product damage and energy use.


Industrial Pumps

Variable speed operation matches flow rates to demand in water treatment, chemical processing, and HVAC circulation systems .


Machine Tools

Provides dynamic torque response for CNC machinery, improving machining precision while reducing energy consumption during idle periods.


FAQ


How does the integrated inverter simplify installation?

Eliminates the need for separate VFD wiring, enclosure cooling, and electromagnetic compatibility (EMC) filtering, reducing installation costs by 30-40% .

Can it replace existing AC motors without system modifications?

Yes, the motor features NEMA and IEC frame compatibility with standard mounting dimensions, enabling direct retrofitting with minimal mechanical changes .

What is the expected payback period for industrial applications?

Typical payback ranges from 8-14 months depending on usage patterns, with longer operating hours accelerating returns .
