EcoTorque-Fan Motor Series 260-25
Available from stock
The Direct Drive Fan motor 260-25 achieves a high capacity while being very compact. It produces over 4kW of mechanical power at 1200 RPM, while only having a building volume of ø261 mm by 116 mm (~10.3 x 4.7 inch).
Opposed to the bulky AC motors that weigh up to 4-times more, take up a lot of space and can block the airflow, the compact design of the EC Fan Motor saves valuable operating space.
In addition, the EC Fan motor is very silent, improving the working environment.

Why Choose a Direct Drive Motor?
The EcoTorque-Fan motor series harnesses direct drive technology to deliver high performance and reliability. Direct drive motors eliminate intermediate components like gearboxes or belt systems, offering several key advantages:
- Reduced Maintenance: Fewer moving parts mean less wear and tear.
- Improved Efficiency: Direct transmission of torque minimizes energy loss.
- Compact Design: Saves valuable space while maximizing performance.
What is PMSM Technology?
PMSM technology is at the heart of our Direct Drive Fan Motors. By leveraging permanent magnets and synchronous operation, these motors achieve higher torque and efficiency compared to traditional AC motors. The outrunner design positions the rotor outside the stator, enabling a compact yet powerful system. This innovation enhances performance while reducing size and weight.
