whining noises! An EC motor under speed control is virtually silent.

 

1. How does this affect energy efficiency?

   Doubling the speed of a motor increases its power input by a factor of 8 so it’s very wasteful to run a fan faster than is required. If you can tailor the fan speed to match the demand, the potential for energy saving is huge. Even when compared to on/off operation, EC speed modulation is much more efficient.

 

   EC fans can also contribute to increasing the overall efficiency of an application. In a cooling system for example, keeping the refrigerant pressure constant rather than having it rise and fall as fans switch on and off has been found to reduce the load on the compressor resulting in even greater energy saving.

 

Advantages of EC technology

 

Very high degree of efficiency

Integrated controller (continuous control)

Very simple connection

Additional functions (pressure control, airflow, speed, temperature, air quality, etc.)

Smaller-sized motor for the same level of performance

Less power consumption

 

Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the environment, enable the direct, simple communication between the host controller and the system

 

Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation

 

 Enable the selection of different power levels thus to get the best match of price and performance according to customers’load requirements
