Description
The ABB 3AUA0000088115 Internal Axial Fan circulates air inside drive housings to reduce temperature rise during continuous operation of motor-driven assemblies. It is applied in HVAC systems with variable speed drives and motor control units where electronic components generate heat during power conversion. The axial flow passes through confined spaces of the enclosure to dissipate thermal buildup from semiconductors and windings. It is positioned within compact motor casings and drive modules to maintain temperature balance across vital parts, ensuring stable electrical performance during contineous operational cycles in ventilation and air movements.
