7. PRODUCT DESCRIPTION
The PFP is a backward curved blade fan equipped by an external permanent magnet rotor motor. The rotor magnets are made by
rare earths (NdFeB) that strongly reduce the motor dimension and, therefore, the fan obstruction. The motor shape itself has been
chosen for increasing the airflow inside the fan scroll.
The Driver is fully integrated into the motor and it is equipped with an active PFC (Power Factor > 0.95 in any state of operation)
and it drives the motor through a sensorless algorithm.
The Fans of series PFP combine high energy efficiency and low noise level. Thanks to the “EC” (electronic commutation) motors,
their electronics integrate speed control and protecting system. This reduces the number of different components required to
provide these functions, compared to fans with traditional motors.
The main feature of EC-motor is operating without slip losses, which allow consuming significantly less power than conventional
AC motors.
This occurs at all speed levels, especially with partial load operation. The EC complete drive system (i.e. the combination of the
permanent-magnet motor with its electronic driver) has a much higher energy efficiency, in comparison with a drive system based
on a conventional AC motor.
