2150W Direct-Drive EC Motor for 72-Inch Heavy-Duty Ventilation with IP55 Protection

This EC motor is a high-performance external rotor electronically commutated permanent magnet synchronous motor, specially designed for HVAC, large fans, pump systems and industrial automation. Adopting a direct-drive brushless structure with integrated intelligent drive control, it delivers high torque, compact size, ultra-low noise and long service life. It replaces traditional internal rotor motors with belts or gearboxes, providing stable and efficient power for your equipment.

• High Torque & Small Footprint: External rotor structure provides shorter axial length, stronger torque at same power with zero transmission loss
• High Efficiency & Cost Reduction: Redesigned electromagnetic circuit and high-fill-factor winding reduce copper consumption and improve efficiency
• Self-Cooling & High Reliability: Rotor exposed to airflow for self-cooling with IP44-IP67 protection for harsh environments
• Maintenance-Free & Long Lifespan: Brushless commutation eliminates mechanical wear, reducing maintenance frequency
• Precise Control & Easy Integration: Native support for PWM, 0-10V, Modbus and CANbus with pre-programmable firmware

• External rotor direct drive with zero mechanical coupling loss
• Brushless electronic commutation with noise ≤36dBA
• High power density, lightweight and compact design
• Integrated intelligent drive for precise control
• Wide voltage compatibility and multiple communication protocols
• Strong customization options for shaft extension, mounting flange, and protection level
• Compliant with international energy efficiency standards

• Fully Customized Matching: Deep customization to your housing, torque curve and communication protocol
• Full-Scenario Engineering Validation: Dedicated components for harsh environments
• Ready to Use Out of Box: Pre-calibrated drive parameters reduce commissioning time
• Quality & Delivery Assurance: ISO9001 certified with strict testing and reliable delivery
• Superior Energy Savings: Up to 30% efficiency improvement compared to conventional motors

The EC motor is an electronically commutated permanent magnet direct-drive motor, which is brushless, more efficient, quieter, more controllable and longer lasting, with up to 30% energy saving. Ordinary AC motors are mostly induction types that require transmission parts, resulting in higher loss, simpler control and more maintenance.

Yes. Shaft extension, mounting flange, cable outlet, torque curve, communication protocol and protection level (IP44-IP67) can all be customized to fit your equipment structure.

With no brush wear or mechanical abrasion, service life depends mainly on bearings and lubrication, reaching tens of thousands of hours under normal conditions. It is virtually maintenance-free with no brush replacement required.

Yes. We provide a direct EC motor replacement solution based on your current installation dimensions, power, interfaces and control mode, enabling fast energy-saving upgrades without major modifications.

Large industrial fans, HVAC systems, pump systems, ventilation equipment and industrial automation lines. It is especially ideal for quiet, high-efficiency, maintenance-free and precision-control applications.
