External Rotor Centrifugal Blower
As product design trends toward greater compactness and integration, the traditional "motor + fan" assembly becomes a bottleneck. The external rotor motor technology reinvents this architecture by making the motor part of the fan itself. WinCend's External Rotor Centrifugal Blower series leverages this integrated, space-saving design to deliver high-pressure airflow in an exceptionally compact and reliable package, making it the ideal choice for OEMs in HVAC, medical devices, electronics cooling, and automotive applications worldwide.
WinCend Engineering: Precision for Demanding Applications
We refine the core external rotor concept with precision engineering and high-quality materials to ensure reliable performance in critical applications.
High-Performance Impeller Design
The impeller is the heart of the blower. WinCend utilizes forward-curved (sirocco) or backward-inclined centrifugal wheels, precision-stamped from aluminum or steel for strength and balance. The blades are aerodynamically optimized to generate high static pressure-a key requirement for overcoming resistance in compact heat sinks, filters, or long, narrow ducts.
Advanced EC (Electronically Commutated) Motor Technology
Our blowers feature integrated brushless EC motors. This technology provides:
1.Inherent Speed Control: Speed can be smoothly and efficiently controlled via a standard 0-10V or PWM signal, allowing for dynamic thermal management.
2.High Efficiency Class: Our motors meet or exceed IE4 and IE5 efficiency standards, significantly reducing operational energy consumption.
3.Low Electromagnetic Interference (EMI): Careful design ensures compliance with EMC directives, making them safe for sensitive electronic environments.
Robust Construction & Sealed Designs
Built for durability, key features include:
1.Double-shielded or sealed bearings with long-life lubrication, suitable for continuous operation.
2.IP54-rated options are available, offering protection against dust and water splashes for challenging environments.
3.Terminal boxes or sealed connectors for reliable electrical connections.
