HMF01.1A-N0K2-D0073-A-500-NNNN

The Bosch Rexroth Indramat HMF01.1A-N0K2-D0073-A-500-NNNN belongs to the HMF Motor Filters series and serves as a high-performance Dv/dt Filter w/ Limiter designed to reduce unwanted electrical interference in inverter-driven motors. With a rated current of 73A and a specific inductance of 3 x 100 μH, this mounted device redirects voltage pulses to their source and mitigates transient overvoltages. Its primary function is to protect motor bearings and windings by attenuating high-frequency voltages and leakage currents, thereby extending motor service life and enhancing system reliability.

Built on a robust Mounted Device design, the HMF01.1A-N0K2-D0073-A-500-NNNN features a nominal voltage rating of 3 x 500 VAC and dimensions of 270 x 315 x 225 mm (D x H x W). The integrated limiter restricts output voltage spikes, ensuring that peak voltages do not exceed 1,000 V. Power dissipation is rated at 160 W, while the unit accommodates motor frequencies up to 200 Hz. The filter is installed at the inverter or converter output and is capable of serving multiple motors in parallel over long supply runs. Its design safeguards against insulation breakdown by maintaining impedance balance across cable terminations.

In addition to core filtering, this device significantly lowers leakage currents in motor cabling when positioned at the inverter output. It is equipped with a type plate displaying part number, voltage and current ratings, and frequency limits. The HMF01.1A-N0K2-D0073-A-500-NNNN meets the IP10 protection standard under IEC 60529 and weighs 15 kg. Shipped in military-grade packaging with a one-year warranty, this filter offers industrial users enhanced durability, efficient voltage suppression, and improved motor longevity, making it an indispensable component for high-demand automation environments.
