Product Description:

Bosch Rexroth Indramat builds the HMF01.1N-N0K1-M0480-N-690-NNNN as part of the HMF Motor Filters series. The unit is installed in the motor lead of drive systems that use HCS04.2E-W0520 or HCS04.2E-W0640 converters. It functions as a three-phase output choke that suppresses high-frequency currents and protects motor insulation from steep voltage edges in industrial automation systems.

The filter carries a continuous load of 530 A, allowing it to follow the full current envelope of large servo axes without magnetic saturation. Its terminals accept voltages up to 3 AC 0...690 V, so the same device can handle low- and medium-voltage drive families that share a common DC bus. The iron core and winding design maintain low impedance across the 0...100 Hz range, which helps prevent unwanted voltage drop during operation. Short-term overload tolerances of 150%/60 s per 10 min; 165%/2 s let the filter absorb regenerative peaks produced during rapid deceleration. An ingress rating of IP00 means the assembly must be mounted inside a switch cabinet; it stands vertically on a back-panel rail, operates at sites up to 1000 m above sea level, and dissipates 530 W of heat that must be removed by forced airflow.

For its current rating, the unit remains compact: the stack depth is 250 mm, the overall width is 200 mm, and the height reaches 245 mm, permitting placement beside contactors or harmonic traps on the same plate. Transport and installation are supported by a mass of 58 kg, and the frame includes a single hoist eye for lifting. Copper and laminated steel components withstand ambient storage between -40...+70 °C; outside that range, insulation aging accelerates. Three single-phase chokes share a common yoke to minimize stray flux without introducing mechanical resonance into the cabinet structure.
