LEMD-AB112X2L1

The LEMD-AB112X2L1 cooling module is produced by Bosch Rexroth Indramat within the Cables And Accessories series. Designed as an axial fan assembly, it is installed in drive cabinets or motor housings to direct airflow across power electronics and prevent thermal accumulation that could trigger derating or shutdown. By maintaining a stable internal temperature, the unit supports consistent performance of servo drives, inverters, and other automation hardware operating in confined enclosures.

The fan is intended for single-phase mains supplies at a nominal 230 V AC. Under this voltage it draws 0.25 A, so control engineers can allocate a modest circuit breaker while still supplying the necessary torque to the rotor. Electrical input is converted into roughly 43 W of mechanical air movement when the network frequency is 60 Hz. That energy drives an impeller with an Axial orientation, allowing a relatively unobstructed path that produces a mean flow of 390 m³/h. This throughput is sufficient to flush the heat-sink channels of medium-frame converters or servo amplifiers during continuous duty.

Further integration factors relate to environment and mechanical layout. Air exits from the B side toward the A side, so component placement must respect this predefined direction. The acoustic emission is limited to 52 dB(A) at the nominal point, helping machine builders meet enclosure sound targets without extra damping. With a mass of only 1.2 kg, the module mounts on sheet-metal doors or rail brackets without exceeding typical load limits. Operation is standardized for a 60 Hz grid but remains stable within a supply window of ±15%, simplifying deployment in facilities with fluctuating voltage.
