Resemble Ebm-past New Energy Ec Centrifugal Fans Gakvabused Sheet Steel With 250mm
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)
| Type | Nominal voltage (VAC) | Frequency (HZ) | Speed (RPM) | Power imput (w) | Current draw (A) | Sound pressure (dB) | Perm.amb.temp

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
Pressure control : A pressure sensor can be connected directly to the Electronic of the EC motor. The pressure control is made by the integrated electronics. No additional control unit is needed. (Rosenberg Versions only)
Master/Slave : This system is used when several fans are used together within a single application. The main fan (Master) is individually pressure controlled. The other fans (slaves) are then speed controlled by the Master fan : Slave Fans are always at the speed of the master fan (Rosenberg Versions only).
