4.3 Ventilation
Motors are cooled through outer air blow (IC 411 according to CEI EN 60034-6) and are equipped
with a plastic radial fan, which operates in both directions.
Ensure that fan cover is installed at a suitable distance from the closest wall so to allow air circulation
and servicing of motor and brake, if tted.
On request, all BX/MX, BE/ME motors and BN/M motors, starting from BN 71 or M1 size, can be sup-
plied with independently power-supplied forced ventilation system.
Motor is cooled by an axial fan with independent power supply and tted on the fan cover (IC 416
cooling system).
Brake motors of BN_BA type and all motors with rear shaft projection (PS option) are excluded.
