Key Features of High Efficiency EC Motors with Separate Mounting Inverter


1. IEC Standard Die-Cast Aluminum Housing

The motor features a durable IEC standard die-cast aluminum housing, offering flexibility for installation in various configurations such as B3, B5, and B14. This makes it ideal for different industrial applications.


2. High Efficiency (IE5 Standard)

Our EC motors meet the IE5 efficiency standard, providing excellent energy savings. This high-efficiency performance helps reduce operational costs, making it an ideal choice for energy-conscious manufacturers and suppliers.


3. Wide Speed Range (300rpm - 3600rpm)

The motor offers an adjustable speed range from 300rpm to 3600rpm, ensuring precise control over airflow and performance. This range is suitable for diverse applications, including HVAC systems, ventilation, and other industrial systems.


4. IP55 Sealed Motor with Optional IP56

The IP55 rating ensures the motor is fully enclosed, protecting it from dust and water splashes. An optional IP56 version is available for more demanding environments, with an external fan (IC411) to enhance cooling.


5. Communication Protocol for Driver Signals

The motor supports communication protocols for driver signals, which simplifies integration into smart control systems. This feature is particularly useful for users requiring remote control and real-time adjustments in industrial or commercial systems.


6. Vector Control and PM Motor Control

The motor requires a Variable Speed Drive (VSD) to operate with vector control or permanent magnet (PM) motor control. This ensures optimal performance and precise control, making it suitable for complex industrial applications and high-performance systems.


7. Customizable Motor Parameters

These motors are designed to work with specific motor parameters, set through the VSD. For each system, motor parameters can be customized, allowing for tailored performance and operational efficiency in specialized applications.


8. VSD-Driven Motor for Optimal Control

These motors must be driven by VSDs, ensuring they cannot be connected directly to standard AC power. This setup guarantees better control over speed and torque, ideal for systems requiring fine-tuned performance and energy efficiency.


This high-efficiency EC motor with separate mounting inverter is perfect for applications requiring precise control and energy savings, such as HVAC, industrial ventilation, and automation systems. As a reliable manufacturer and supplier, we ensure these motors meet the highest industry standards.
