Product Description

EC outer rotor fan motors have many advantages compared to traditional AC fan motors:

Compact & Space-Saving

Direct integration of rotor and load reduces volume by 30%-50% and weight by 20%-30% compared to same-power internal rotor motors. Suitable for embedded installation (e.g., equipment interiors, narrow enclosures) with no need for transmission space.

High Energy Efficiency & Low Operating Costs

Motor efficiency reaches 85%-95%, meeting IE4-IE5 high-efficiency standards—saving 30%-60% more electricity than traditional AC motors. During variable-speed operation, energy consumption decreases linearly with load demand, eliminating “overcapacity waste.”

Stable Operation & Ultra-Low Noise

No friction noise from transmission parts. Coaxial rotation of rotor and load ensures high dynamic balance precision (usually ≤0.5g), with operating noise 3-8dB lower than internal rotor motors. Some models achieve noise levels below 50dB.

Flexible Speed Regulation & Strong Adaptability

Built-in EC control unit (ECU) supports 0-100% stepless speed regulation. Compatible with 0-10V/4-20mA analog control and RS485/MODBUS digital control, enabling integration with PLCs and IoT systems for diverse load requirements.

Photovoltaic

The high-voltage motor can be combined with the photovoltaic unit and storage battery through a unique High-voltage solar energizer which makes solar energy,battery power and grid power complement each other to supply power to multiple motors 24/7. These solution form a high-efficiency conversion unit to optimize solar energy utilization and reduce electricity costs significantly.
