EC fans consume, on average, about 30% less electricity than conventional AC fans but what is an EC fan and what makes it more efficient?
Very high degree of efficiency.
Integrated controller (continuous control).
Very simple connection.
Additional functions (pressure control, etc.).
Smaller-sized motor for the same level of performance.
Less power consumption.
Permanent-magnet brushless DC motor within the rotor
The stator is driven by electronic switches (which replace the Carbon brushes), controlled by a microcontroller.
Electronic system (hall effect sensor or software is used to recognize the rotor position)
AC operated (230Volts Single phase or 380/480Volts 3phase, 50/60Hz)
Energy savings : Minimum power consumption & better efficiency than AC equivalent.
Control : 100% speed controllable, not frequency dependant. Can be set-up for constant airflow or constant pressure applications, 0-10VDC or PWM control signal.
Low motor temperature : for longer lifetime than AC equivalent
Simplicity : Electronic & power transformation are completely integrated within the motor.
High performance : Speed can be driven up to 3600rpm, one EC fan replace multiple type of motors (2, 4 and 6 pole)
Easy connection : No complicated wiring and set-up with a frequency controller EC fans have very little configuration.
Significant noise reduction.
Remote monitoring via. BMS
Typical AC motors have losses in terms of power consumption (copper + iron losses), slippage and frictional losses (mechanical power). EC motor has no slippage losses, reducing losses and increasing efficiency.
