What is a generation 3 EC fan motor?

The Generation 3 EC fan motor drives are used to drive axial fans and backward curved impellers in environments where power, reliability and control are critical. Advanced manufacturing technology enables 40% more motor winding density creating 20% to 30% increased power in the same footprint.

Can industrial fans be used for power generation?

We can design and supply industrial fans to successfully operate in the hazardous or explosive environments of power generation. Forced draft, induced draft and dust control fans all feature in power generation applications, with industrial fans needing to be able to operate effectively at extremely high temperatures.

Are centrifugal fans better than axial fans?

When compared to axial fans, centrifugal fans can develop higher pressure airflows, although at lower volumetric flow rates. In spite of this, centrifugal fans create a steadier air flow than axial fans and can achieve high levels of efficiency, although they also require higher input power.

What are the advantages and disadvantages of axial fans?

Among the advantages of axial fans are high efficiency, low noise and lower input power requirements compared with other fan types. While axial fans create airflow with high flow rates, the airflows have low pressure. For wind turbine applications, axial fans are ideally suited for tower or nacelle cooling. Figure 3. Centrifugal fan.

What is a centrifugal fan used for?

Centrifugal fans are ideal for high pressure applications such as drying and air conditioning systems, and for wind turbine applications they may be used for generator and nacelle cooling. Figure 4. Backward curved motorized impeller.

Do wind turbines have cooling fans?

Wind turbines that are used for power generation have numerous applications for cooling fans. Although fans are fundamentally selected on the basis of volumetric air flow, static pressure and size, numerous other factors must be considered for wind turbine applications.
